1. GENERAL INFORMATION

This section provides a description of the instrument clusters fitted to the MY 2003 VY and V2 Series vehicles.

1.1 GENERAL DESCRIPTION

Two versions of instrument cluster assemblies are used on VY Series Models, one with a single window

Multi-function Display (MFD) and the other with a triple window display, the centre window being the MFD. A trip

computer is standard equipment on all VY Series Models. Refer to 1.4 TRIP COMPUTER — SINGLE WINDOW

TYPE or 1.5 TRIP COMPUTER — TRIPLE WINDOW TYPE in this Section for an explanation of trip computer

functions.

The instrum ent cluster assem bly on VY Series Models consists of specific style analogue type instrument gauges.

An electr onic s peedometer is situated to the r ight of centr e, with the odom eter and tr ip/odometer r eadings s tor ed on

the trip computer and displayed on the MFD. A tachometer is located to the left of centre, a tem perature gauge to

the left of the tachometer and a fuel gauge to the right of the speedometer. The speedometer indicates up to

250 km/h on all models except the SS, which indicates up to 260 km/h.

Instrument cluster illumination is by Light Emitting Diodes (LEDs) within the instrument cluster. The LEDs are not

serviceable.

A switch assembly located in the instrument facia operates the trip computer on both instrument cluster assemblies.

NOTE: If installing a new instrument cluster, the original odometer reading, together with other important

parameters, must be transferred into the replacement instrument cluster. This can be done by an authorised Holden

Retailer using TECH 2.

Figure 12C-1 illustrates the instrument cluster fitted to Level 1 vehicles.

NOTE: Should it be necessary to electric weld on any vehicle at any time, removal of the instrument cluster is

mandatory. Failure to do so will result in damage to the instrument gauge circuitry.

If the battery is disconnected for any reason, the following accumulative values are reset:

• Trip Time

• Trip Distance

• Fuel Used

• Average Fuel

• Average Speed

• Stop Watch (if enabled and display ing a non-zero figure).

On all VY Series Models the clock is incorporated into the audio system LCD window.

1.2 INSTRUMENT FACIA SWITCHES

Details on the trip com puter switch are pr ovided in this Section. For inform ation on other instrum ent f acia switches,

refer to Section 12B, LIGHTING SYSTEM.

For vehicles with an adjustable height power antenna, the antenna up and down control switches are loc ated in the

radio control panel.

1.3 INSTRUMENT ILLUMINATION

The headlamp switch incorporates a variable intensity instrument cluster illumination control (slider), and a four-

position switch for off, parking, headlamps on and an auto headlamps on switch mode. In auto headlamps on mode,

cluster illumination is dependant upon whether the lights are on or off.

With the headlamp switch in the OFF position, the MFD illumination (or the side LCD on triple-window instrument

cluster) is set to maximum backlighting. In any of the other positions, the MFD illumination (or side LCD) is

controlled by the position of the slider.

The dial, pointer and MFD illumination is controlled by the slider on the headlamp switch. Moving the slider varies an

input voltage to the Body Control Module (BCM), which in turn sends an illumination level signal to the Instrument

Cluster via the serial data communications bus. The Instrument Cluster interprets the illumination level signal and

controls the illumination level accordingly. For further details, refer to Section 12J, BODY CONTROL MODULE.

1.4 TRIP COMPUTE R — S I NGLE WINDOW CLUSTE R

OPERATION

The buttons for the trip com puter are loc ated to the

left of the instrument cluster. The four buttons in

the switch assembly are MODE (1), SET (2), UP

(3) and DOWN (4).

All the trip computer screens are displayed on the

MFD, which is located in the centre of the

instrument cluster below the gauges.

When the ignition is turned on, the MFD initially

displays the start up sequence, then displays the

same trip computer functions as when the ignition

was last turned off.

To res et the trip com puter func tions, pres s the SET

button. This will reset all functions, with the

exception of Distance to Empty, Overspeed

Warning, Odometer, Time to Go and Distance to

Go.

To scroll between the trip computer functions,

press the MODE button for less than 2 seconds.

NOTE: If the wrong buttons have been accidentally

pressed, c aus ing the dis play to show other than the

normal readings, turn the ignition off, then on again.

Personal customisation of the trip computer is also

possible. Refer to 1.8 CUSTOMISATION MODE in

this Section.

Figure 12C-4

The trip c omputer f unctional sequence for the single-window clus ter is shown in Figure 12C-5. Pressing the MODE

button steps through the screens as shown in the flowchart. The Distance to Go function must be enabled in

Customisation Mode before this screen can be accessed using the MODE button.

NOTE: If the instrument cluster is set as a Police cluster, the MFD will always default to True Speed Mode at

ignition on. The digital speedometer is the default display for Police instrument clusters.

Figure 12C-5

ODOMETER / TRIP METER

The odometer records the kilometres travelled

since the vehicle was built.

The trip meter displays the kilometres travelled

from the start of a particular trip. The trip meter

reading is res et to zero by pressing the SET button

for less than 2 seconds while the Odometer / Trip

Meter screen is displayed.

Press the MODE button to advance to the next

screen. If the Distance to Go function is enabled in

Customisation Mode then the Distance / Time to

Go screen will be the next to be displayed.

Otherwise the next screen will be the Distance to

Empty screen.

Figure 12C-6

DISTANCE / TIME TO GO

This function is enabled in Customisation Mode.

At the start of a trip, an estimate of distance to

arrival should be made. Tap the UP or DOWN

buttons on the trip com puter switch until the display

shows the estimated trip distance.

W hile the vehicle is being driven, the trip computer

constantly updates the Time to Go based on

changing driving speeds. The Time to Go value is

displayed as follows:

• In 1 minute increments if the Time to Go is

less than 10 minutes.

• In 5 minute increments if the Time to Go is

more than 10 minutes, but less than 2 hours.

• In 10 minute increments if the Time to Go is

mor e than 2 hours , but less than 99 hours and

59 minutes.

• In 1 hour inc rements if the T ime to Go is more

than 99 hours and 59 minutes.

The UP and DOW N buttons can be used to adjust

the distance (kilometres) at any time the display is

showing.

To reset the distance to a value set in

Customisation Mode or the default of 500 km,

press the SET button for less than 2 seconds while

the Distance / Time to Go screen is displayed.

Press the MODE button to advanc e to the Distance

to Empty screen.

Figure 12C-7

DISTANCE TO EMPTY

Distance to Empty is an estimate of how far the

current fuel will last. It is based on previous fuel

usage and is frequently updated. Therefore, as

conditions become suited to more economical

driving the Distance to Empty may actually

increase, for example when changing from city to

highway driving.

Press the MO DE button to advance to the Average

Speed / Fuel screen.

Figure 12C-8

3. DIAGNOSTICS

3.1 BASIC KNOWLEDGE REQUIRED

Before attempting to diagnose the instrument cluster you must have a good understanding of electrical system

basics and the use of circuit testing tools. Without this basic knowledge it will be difficult to use the diagnostic

procedures detailed in this Section.

Some electric al basics , as well as basic troubleshooting procedures and hints on the use of circuit testing tools are

covered in Section 12P, WIRING DIAGRAMS.

Basic Electrical Circuits — You should understand the basic theory of electricity, series and parallel circuits, and

voltage drops across series resistors. You should know the meaning of voltage (volts), current (amps), and

resistanc e (ohms ). You should understand what happens in a circ uit with an open or shorted wire (shorted either to

voltage or ground). You should also be able to read and understand a wiring diagram.

Additionally, a knowledge of AC theory including inductance, capacitance and impedance would be useful.

Use of Circuit Testing Tools — You should know how to use a jumper lead to test circuits. You should be familiar

with the use of a high input impedance (10 Megohm) digital type multimeter such as Tool No. 3588 (J39200) or

equivalent and be able to measure voltage, current, and resistance. You should be familiar with the proper use of

the TECH 2 Diagnostic Scan Tool.

NOTE: The vehicle’s battery must be removed before performing any ground resistance checks with a high

impedance multimeter. Refer to Section 00, 5. BATTERY DISCONNECTION PROCEDURES.

Techline

3.2 PRELIMINARY SYSTEM DIAGNOSIS

When investigating any complaint of an instrument cluster problem or malfunction, always begin diagnosis with a

circuit check, refer to 3.8 INSTRUMENT DIAGNOSTIC PROCEDURES, DIAGNOSTIC CIRCUIT CHECK chart in

this Section.

The diagnostic circuit check is a preliminary procedure that checks to ensure the instrument cluster is

communicating on the serial data line as well as helping to identify the problem.

3.3 INSTRUME NT CLUS TER DIAGNOSTICS

Fault diagnosis for the instrument cluster is divided into two areas; faults which can be remedied by checking the

operation of components connected to the instrument cluster, and those which can be checked by using the

TECH 2 Diagnostic Tool.

The instrum ent cluster can provide a preliminary indication that there is a fault either on the serial data bus, within

the instrument cluster or the BCM. When the instrument cluster does not receive a valid or complete serial data

message for 10 seconds, the MFD shows the message 'Service Error – Contact Dealer'. This error message

indicates a short circuit on the serial data bus, an open circuit to the instrument cluster or a fault within the

instrument cluster. Pressing the MODE button on the trip computer switch clears the error message. In this

instance, the icon N is shown in the left-hand side of the MFD. If the fault is associated with the fuel sender, the

mes sage displayed is 'Fuel Sender Error – Contact Dealer ', and the appropriate Petrol/LPG symbol is displayed on

the left-hand side of the MFD.

Additionally, when a fault is detected, the instrum ent cluster sets a Diagnos tic Trouble Code (DT C) that represents

that particular problem or failure.

DIAGNOSTIC TROUBLE CODES

There are two types of DTC, current and history.

• A Current DT C is active only for the per iod that the f ault is pres ent and is indicated by the icon/me ssage on the

instrument cluster. When the fault is cleared, the Current DTC and the icon / message are also cleared.

• The History DTC is set at the same time as the Current DTC, and is stored in memory within the instrument

cluster to provide information on vehicle system operation over a period of time. History DTC are read and

cleared from memory by TECH 2.

Each DTC is allocated a number from 0 to 31. The following table provides details on each of the DTC.

DTC 0 Not Used DTC 16 Petrol Level Sender Stuck

DTC 1 Petrol Level Sender Signal Voltage Too Low DTC 17 LPG Level Sender Stuck

DTC 2 Petrol Level Sender Signal Voltage Intermittent DTC 18 Not Used

The Diagnostic Mode also has a self-test function (Full Test) to verify correct instrument cluster operation. When

activated, the following occurs:

• The temperature gauge and the fuel gauge are set to the half-way mark (50%).

• The tachometer is set to 3000 rpm.

• The speedometer is set to 100 km/h.

• The chime is activated at 1 kHz.

• The telltale LEDs that are driven by either the internal microprocessor or from the serial data line are

illuminated. These are SRS, Brake Park/Fail, Seat Belt and Shift Up (HSV only).

• All segments of the MFD and the side LCDs (triple-window cluster only) are illuminated.

Press the MODE button to return to the GM Part Number screen, or the SET button to exit the instrument cluster

Diagnostic Mode.

Faults can be identified by using TECH 2 to test instruments and force values and conditions into the instrument

cluster. The results of thes e test s c an be us ed to diagnose pr oblems in the instrument cluster such as faulty gauges

and switches.

Faults within other components can be identified after using TECH 2 to confirm correct operation of the instruments.

For example, if there was a reported fault with the speedometer gauge and TECH 2 diagnosed the gauge as

working c orrectly, then the fault would lie in the Powertrain Control Module (PCM) or in the har ness from the speed

sensor to the PCM, both of which would then require further testing.

USE OF TECH 2 DIA GNOSTIC TOOL WITH INTERMITTENT FAULTS

The TECH 2 Diagnostic Tool allows m anipulation of wiring harnesses , while observing the TECH 2 Diagnostic Tool

readout. If the pr oblem seem s to be related to certain param eters that can be check ed on the TECH 2 Diagnostic

Tool, they should be checked while driving the vehicle. If there does not seem to be any connection between the

problem and any specif ic circuit, the T ECH 2 Diagnostic Tool can be us ed to monitor eac h param eter, watching for

a period of time to see if there is any change in the readings that indicates intermittent operation.

The TECH 2 Diagnostic T ool saves time in diagnos is and helps to prevent the replacem ent of good parts . The key

to using the TECH 2 Diagnostic Tool successfully is the TECHnicians ability to understand the system being

diagnosed, as well as under standing the TECH 2 Diagnostic T ool oper ation and limitations. The T ECHnician s hould

read the TECH 2 User’s Guide to become familiar with the TECH 2 Diagnostic Tool operation.

With an understanding of the data which the tool displays, and knowledge of the circuits involved, the tool can be

very useful in obtaining information which would be more difficult or impossible to obtain with other equipment.

The TECH 2 Diagnostic Tool does not make the use of diagnostic charts unnecessary, nor can it indicate exactly

where a problem is in a particular circuit. Diagnostic charts incorporate diagnostic procedures that require the use of

a TECH 2 Diagnostic Tool.

Throughout the diagnostic procedures are references to various module or component connectors. These

connectors are illustrated in the following figures.

3.4 DIAGNOSING FAULTS NOT COVERED BY DIAGNOSTIC TROUBLE CODES

The instrument cluster telltales and MFD are triggered by information or signals which can be either internally

generated, or be input to the cluster via the serial data bus from an external module or component, or hard-wired

from a module or switch. Some of these components do not set a DTC in the event of a component failure. The

following diagnostic procedures are devised to assist in these cases:

• Diagnosis for Hard-wired Input Signals • Low Traction Control Display

• Diagnosis for Internally Generated Signals • Generator Warning

• Diagnosis for Serial Data Input Signals • Trip Computer Switch

• Front Fog Lamps On • Instrument Illumination

• Turn Signal Indicator Lamps • Brake Fail / Park Brake Warning

INSTRUMENT ILLUMINATION

Figure 12C-298

CIRCUIT DESCRIPTION

The headlamp switch incorporates a variable intensity instrument cluster illumination control (slider) and a four-

position switch for Off, Park, Headlamps and Auto Headlamps On switch mode.

With the switch in the Off position (open circuit), the MFD (and side LCDs for triple-window cluster) are set at

maximum backlighting. W hen the switch is in the Park , Headlamp or Auto positions, a 12 volt signal is supplied to

the instrum ent cluster f rom the park lam p relay, and the MFD (and side LCDs for triple-window cluster) are s et to a

reduced level of backlighting.

The dial and pointer illumination are controlled by the slider control on the headlamp switch. The slider varies an

input voltage to the BCM, which in turn transmits an illumination level to the instrument cluster via the Serial

Communications Bus. The instrument cluster interprets this illumination level and controls the illumination

accordingly .

SPEEDOMETER DIAGNOSIS

Figure 12C-300

CIRCUIT DESCRIPTION

The instrument cluster receives vehicle speed information from the Powertrain Control Module (PCM) via circuit

5197. The PCM pulses this circuit to ground. The number of pulses varies with tyre size.

The PCM receives vehicle speed inform ation from the vehicle speed sensor located in the transmission assem bly.

A voltage is produced by the speed sensor and is fed to the PCM, which filters and shapes the signal. The PCM

then counts the number of pulses received in a given time to determine the vehicle speed.

Once the PCM has calculated the vehicle speed, it then pulses circuit 5197 to ground. This causes the 12 volts at

instrum ent cluster ter minal X 1-5 to be pulled down to less than 0.5 volt. The instr ument cluster then determ ines the

vehicle speed and the kilometres travelled from the number of pulses it receives.

3.5 SERIAL DATA COMMUNICATION

GENERAL INFORMATION

The VY Series m odel uses a BUS MASTER com munication system, where the BCM is the bus m aster. The serial

data bus comprises:

• the primary serial data bus, circuit 800,

• the secondary serial data bus, circuit 1061, and

• the tertiary serial data bus, circuit 774.

The BCM periodically polls (surveys) each device on the bus and requests status data.

The devices connected are:

• Body Control Module (BCM).

• Powertrain Control Module (PCM) for V6 and V6 supercharged engines.

• Powertrain Interface Module (PIM) for GEN III V8 engines only.

• Occupant Climate Control (OCC).

• Instrument Cluster (INS).

• Anti-lock Brake (ABS) or Anti-lock Brake / Traction Control System (ABS / TCS).

• Supplementary Restraint System (SRS).

• Entertainment Sy stem.

• External diagnostic tool (TECH 2).

The data provided by each device may be utilised by any device connected to the bus.

Each device has a unique response Message Identifier Word (MIW) for ease of identification.

The bus mas ter (BCM) polls eac h device with a serial data m essage which includes that device’s MIW. T he device

responds by putting a serial data message onto the bus which includes its MIW and data, which is retrieved and

utilised by any device requiring it.

The BCM polls each device for a st atus update, once every 300 m illiseconds. The exception to this being the PCM

(V6), the PIM (GEN III V8) and the Entertainment System which are polled twice every 300 milliseconds.

The TECH 2 diagnostic tool can be used to read serial data on the data bus and analyse faults in the instrument

cluster and its related components.

3.8 INSTRUMENT DIAGNOSTIC PROCEDURES

INTRODUCTION

The following charts are designed to provide fast and efficient fault location of the instruments. Each diagnostic

chart consists of a diagnostic chart and pertinent information including Diagnostic Trouble Code (DTC) setting

parameters and, in most charts, circuit diagrams.

W hen carrying out wiring checks as directed by the diagnostic charts, rather than probe terminals and connectors

with incorrect sized multimeter connections, use the adaptors contained in connector test adaptor kit J35616-A (KM-

609), as shown in the f ollowing illustration. T his will prevent any possibility of spreading or dam aging wiring harness

terminals, which may later cause a system intermittent failure.

Figure 12C-313

Figure 12C-314

DIAGNOSTIC CIRCUIT CHECK

W hen investigating any com plaint of an instrum ent cluster problem or malf unction, always begin diagnos is with the

following diagnostic circuit check. This check is a preliminary procedure that ensures that the instrument cluster is

powered up, communicating on the serial data line, helping to identify a problem or malfunction, and directing the

reader to the appropriate diagnostic chart in this Section.

With TECH 2 connected to the DLC and the ignition switched on, TECH 2 should display serial data

communication. If TECH 2 does not display serial data, the serial data circuit may be open or shorted.

The entertainment system and several other control modules are connected to the serial data line. The control

modules are the PCM, PIM (GEN III V8 only) BCM, ABS or ABS / T CS, OCC and SRS. The enter tainment system

or ANY one of the control m odules could caus e a fault on the serial data line. T his fault could result in T ECH 2 not

being able to display serial data.

DTC 1 — PETROL LEVEL SENDER SIGNAL VOLTAGE TOO LOW

Figure 12C-315

CIRCUIT DESCRIPTION

The instrument cluster supplies a 12 volt reference voltage and a ground circuit to the fuel gauge sender unit. The

fuel sender provides a resistanc e value to the instrument c luster based on its position relative to the f uel level. The

fuel sender resistance will vary between 40 ± 5 ohms and 250 ± 5 ohms from no fuel in the tank to full tank.

DTC 1 will set if the fuel sender resistance is less than 12.9 ohms for a period of 30 seconds. The DTC is reset

when the fuel sender resistance returns to its normal operating range for a period of 60 seconds. The DTC is

logged as a History DTC.

When a DTC 1 is set the fuel gauge will display the fuel tank level as empty irrespective of actual fuel level.

DIAGNOSTIC AIDS

The TECH 2 diagnostic tool reads fuel sender position as a voltage between 0 and 5 volts. The fuel sender signal

resistanc e should be between 40 ± 5 ohm s and 250 ± 5 ohms when the fuel sender is functioning correctly. The fuel

sender voltage should increase at a steady rate as the fuel level increases.

The multimeter allows continuity of the wiring harness to be checked. Harness voltage can also be confirmed at

connector locations.

Check for any damage to the harness which could cause an intermittent open or short to ground or backed-out

terminals at the instrument cluster connectors, broken connector locks, improperly formed or damaged terminals.

DTC 5 — LPG LEVEL SENDER SIGNAL VOLTAGE TOO LOW

Figure 12C-319

CIRCUIT DESCRIPTION

The instrument cluster supplies a 12 volt reference voltage to the LPG gauge sender unit. The LPG sender provides

a resistance value to the instrument cluster based on its position relative to the LPG level. The LPG sender

resistance will vary between 40 ± 5 ohms and 250 ± 5 ohms from no LPG in the tank to full tank.

NOTE: If a vehicle is not fitted with LPG and DTC 5 is set, verify the instrument c lus ter configuration progr amm ing

with TECH 2. Refer to 3.15 PROGRAM in this Section.

DTC 5 will set if the LPG sender resistance is less than 12.9 ohms for a period of 30 seconds. The DTC is reset

when the LPG sender resistance returns to its normal operating range for a period of 60 seconds. The DTC is

logged as a History DTC.

When a DTC 5 is set the LPG gauge will display the LPG tank level as empty when LPG mode is selected

irrespective of actual fuel level.

DIAGNOSTIC AIDS

The TECH 2 diagnos tic tool reads LPG sender pos ition as a voltage between 0 and 5 volts. The LPG sender signal

resistance should be between 40 ± 5 ohms and 250 ± 5 ohms when the LPG sender is functioning correctly. The

LPG sender voltage should increase at a steady rate as the LPG level increases.

The multimeter allows continuity of the wiring harness to be checked. Harness voltage can also be confirmed at

connector locations.

Check for any damage to the harness which could cause an intermittent open or short to ground or backed out

terminals at the instrument cluster connectors, broken connector locks, improperly formed or damaged terminals.

DTC 11 — NO SERIAL DATA FROM PCM

Figure 12C-324

CIRCUIT DESCRIPTION

The PCM s ends s erial data to the BCM along the prim ar y s erial data bus, c ircuit 800. Serial data is then s ent to the

instrument cluster along the secondary serial data bus, circuit 1061. The following data is read by the instrument

cluster, which then indicates the status as appropriate on the MFD and/or cluster telltales:

• Oil pressure

• High temperature

• Power Mode

• Check engine (powertrain)

• Engine oil life

• Transmission oil life

As the PCM used in conjunction with the GEN III V8 engine is different to that used with the V6 engine, a Powertrain

Interface Module (PIM) is required to convert the serial data generated by the PCM into serial data that is

compatible with the BCM.

DTC 11 will set if there is no PCM data m ess age on the bus for m ore than 10 seconds. In prac tice the trouble c ode

is set somewhere between 10 and 20 seconds after the last PCM data message is received by the instrument

DTC 12 — NO SERIAL DATA FROM SDM

Figure 12C-325

CIRCUIT DESCRIPTION

The SRS Sensing and Diagnostic Module ( SDM) sends serial data along the tertiary serial data bus, cir cuit 774, to

the BCM and then on to the instrument cluster on the secondary serial data bus, circuit 1061. This is read by the

instrument cluster, which displays the status of the SDM on the MFD and cluster telltale.

NOTE: There are two versions of SDM used by the SRS. Version 8.0 is used on vehicles with either 2-loop (left-

hand drive only), 3-loop or 4-loop systems, while version 8.1 is used on vehicles with a 6-loop system. For more

information, refer to Section 12M, OCCUPANT PROTECTION SYSTEM.

DTC 12 will set if there is no serial data being received from the SDM. The DTC is reset within 10 seconds of the

arrival of a SDM data message on the bus. The DTC is logged as a History DTC.

DIAGNOSTIC AIDS

By manipulating the harnesses at the various connectors it is often possible to isolate the cause of the circuit

interruption. This harness can then be removed and repaired.

Check for any damage to the harness which could cause an intermittent open or short to ground or backed out

terminals at the instrument cluster connectors, broken connector locks, improperly formed or damaged terminals.

The multimeter allows continuity of the wiring harness circuit 774 to be checked.

If the fault cannot be found in the harness then the fault may lie in the SDM or the BCM. Refer to

CIRCUIT DESCRIPTION

W hen investigating any com plaint of an Instrum ent cluster problem or malfunction, always begin diagnosis with the

diagnostic circuit check. This check is a preliminary procedure that checks that the Instrument cluster is powered

up, communicating on the serial data line, helping to identify a problem or malfunction and directing the reader to

the appropriate diagnostic chart in this section.

W ith TECH 2 c onnected to the DLC and ignition switched on, TECH 2 should display serial data comm unication. If

TECH 2 does not display serial data, the serial data circuit maybe open or shorted.

There are several other control modules that are connected to the serial data line (PCM, PIM (GEN III V8 only),

BCM, OCC, ABS or ABS / TCS, instrum ent cluster, Radio and SDM). Any of these control m odules could cause a

fault on the serial data line. This fault could result in TECH 2 not being able to display serial data.

DTC 14 will set if there is no serial data m essage on the serial data bus for more than 10 seconds. In practice, the

trouble code is set somewhere between 10 and 20 seconds after the last serial data message is received by the

instrument cluster. The trouble code is reset within 10 seconds of the arrival of an instrument cluster poll from the

BCM. The DTC is logged as a History DTC.

DTC 16 — PETROL LEVEL SENDER STUCK

Figure 12C-329

CIRCUIT DESCRIPTION

The instrument cluster supplies a 12 volt reference voltage and a ground circuit to the fuel gauge sender unit. The

fuel sender provides a resistanc e value to the instrument c luster based on its position relative to the f uel level. The

fuel sender resistance will vary between 40 ± 5 ohms and 250 ± 5 ohms from no fuel in the tank to full tank.

DTC 16 will set if the f uel s ender r es istanc e does not change dur ing a period that the PCM indic ates the usage of at

least 15 litres of f uel. The DTC is reset when the fuel sender resistance returns to its normal operating range for a

period of 60 seconds. The DTC is logged as a History DTC.

When a DTC 16 is set the fuel gauge will display the fuel tank level as empty irrespective of actual fuel level.

DIAGNOSTIC AIDS

The TECH 2 diagnostic tool reads fuel sender position as a voltage between 0 and 5 volts. The fuel sender signal

resistanc e should be between 40 ± 5 ohm s and 250 ± 5 ohms when the fuel sender is functioning correctly. The fuel

sender voltage should increase at a steady rate as the fuel level increases.

The multimeter allows continuity of the wiring harness to be checked. Harness voltage can also be confirmed at

connector locations.

DTC 24 — EE CHECKSUM = FAILURE

CIRCUIT DESCRIPTION

The EEPROM (Electrically Erasable Programm able Read Only Mem ory) is part of the printed circuit board housed

within the instrument cluster. It stores variables required in the operation of the instrument cluster and in the

interpretation of the inc oming data and can be progr amm ed for dif f er ent instr ument levels. If a DTC 24 was set as a

result of interrupted instrument programming then the following diagnostic table will need to be followed.

DTC 24 will set if the EEPROM checksum is incorrect. The testing of the EEPROM checksum occurs every time the

ignition is turned on. T he DT C is res et when the EEPROM check sum is tested as being correct. The DTC is logged

as a History DTC.
