1 General Description

1.1 General Information

There are a number of reasons for including this Section in the MY 2005 range of vehicles:

1 There are now three means of serial data communication available between the various electronic control modules

in the vehicle range;

• Universal Asynchronous Receive and Transmit (UART) protocol.

• Class II.

• General Motors Local Area Network (GM LAN) for the Alloytec range of V6 engines.

2 Alloytec engines have separate engine and transmissi on co ntrol modules, depen ding on engine and transmission

configuration.

Figure 0D – 1 – V6 Serial Data Communications

Vehicle Diagnostics 0D – 3

0D – 3

3 A Powertrain Interface Module (PIM) is also required as the hard ware and serial communications interfac e for both

the V6 and GEN III V8 engines. The PIM acts as a transparent bi-directional translation device that allows data to

flow between modules with GM LAN protocol and modules with UART protocol, as shown in Figures 0D-1 and

0D-2.

4 With the communication necessary between the engine and transmission modules, there are instances where the

engine control module (ECM) could set a diagnostic trouble code (DTC) that would also be detected by the

transmission control module (TCM).

Therefore, to ensure that the most efficient and effective diagnostic process is followed, a ‘tiered approach’ to the

diagnostic process for electric al systems within the vehicle is now more important than ever.

Figure 0A – 2 – GEN III V8 Serial Data Communications

Vehicle Diagnostics 0D – 4

0D – 4

As shown in the previous two circuit diagrams, the Body Control Module (BCM) remains as the ‘Bus Master’ that

periodically polls (or surveys) each of the following devices on the serial data bus (including the BCM itself), requesting

status data:

• V6 Engine Control Module (ECM) and Transmission Control Module (TCM), via the Powertrain Interface Module

(PIM).

• GEN III V8 Powertrain Control Module (PCM) and Audio Interface Module (AIM) if fitted, via the Powertrain

Interface Module (PIM).

• Antilock Braking System / Traction Control System (ABS / TCS) module (GEN III V8 Engine) or Antilock Braking

System / Traction Control System (ABS / TCS) module, via the PIM (V6 Engines).

• Electronic Stability Program (ESP) and the Steering Angle Sensor (SAS), via the PIM (V6 Engines).

• Instrument cluster (INS).

• Telematics Control Module.

• Supplemental Restraint System (SRS) Sensing Diagnostic Module (SDM).

• Audio System Head Unit (AHU).

• Premium Sound Amplifier (PSA)

• Occupant Climate Control (OCC) Module.

• Memory Seat and Mirror Module (MSM).

• Multi Function Display (MFD) via the AHU.

• Body Control Module (BCM)

• Tech 2 diagnostic scan tool.

From this list it will be apparent that only those modules fitted to a specific vehicle, will be polled.

The BCM polls each device for a status report every 300 milliseconds, with the exception of the ECM, TCM, and the

AHU, which are polled every 150 millisecon ds.

1.2 A Tiered Approach to Diagnostics

Resulting from the increased compl exity and communication s systems utilised in MY 2005 range of vehicles, this three

stage approach to the diagnostic process must be un dertaken in the specified manner, if misdiagnosis and the

unnecessary replacement of soun d components is to be avoided.

Step 1 Diagnostic System Check – Vehicle

All vehicle diagnostic procedures are organised in a logical structure that begins with the Diagnostic S ys tem Check –

Vehicle, detailed in this Section. The Diagnostic System Check – Vehicle must always be referred to first, as you will be

directed through the logical steps nec essary to diagnose any ve hicle electrical fault condition.

When working through the Di agnostic System Check – Vehicle, you will be directed to a specific system or diagnostic

system check (e.g. automatic transmission, BCM, etc). Activating the hyperlink provided will then take you to the system

check required.

Step 2 Diagnostic System Check – System

By working through this specific system diagnostic system check, you will be directed to either a Diagnostic Trouble

Code (DTC) table or to other sections within the service information to assist in the solutio n of a vehicl e related problem.

This referral may be to the Symptoms section included for all systems or to intermittent electrical circuit problems.

Through the process of completing the i ndividual system diagnostic system check, you will be directed to the Diagnostic

Trouble Code (DTC) Tables, assuming that there is a DTC currently stored.

Step 3 Diagnostic Trouble Code (DTC) Tables

All diagnostic tables are developed with the following assumptions:

• The vehicle functioned correctly at the time of assembly,

• There are no multiple faults, and

• The problem currently exists.

An understanding of and the correct use of the diagnostic tables is essential if the diagnostic time is to be minimised

and/or to prevent poor diagnosis.

Multiple DTCs Fault Condition

In any given electronic system, some fault conditions trigger multiple component DTCs even if the fault cond ition exists

only in a single component. If there are multiple DTCs stored, the Technician must view and record all DTCs logged.

The relationship between the logged DTCs can then be reviewed to determine the so urce of the fault condition. Always

begin the diagnostic process by compl eting the Diagnostic Table for the fault condition that may trigger other DTCs to

set.

The following fault conditions ma y trigger multiple DTCs:

• A system voltage that is too low may cause incorrect system management operation or a component to

malfunction.

• A system voltage that is too high may damage the system control module and/or other sensitive electronic

components.

• A fault condition in the system control module Read Only Memory (ROM) or Random Access Memory (RAM).

• A fault condition in the system control module internal circuitry or programming.

• An improperly connected sen sor or component wiring harness connector.

• An electrical fault condition in shared system electrical circuits may trigger DTCs for components or sensors that

are connected to the same faulty circuit (e.g. an open in one of the GMLAN circuits). Test the electrical circuit of the

appropriate sensor or components to isolate the fault condition. Each Section contains detailed electrical circuits

relating to that system.

If there are no obvious faults to begin a multiple set DTC fault condition, always start with the lowest number, then work

progressively through each.

Symptom Diagnostics

Should all of the following conditions exist, refer to the Symptom Tables, that may be provided in the particular system:

• An system fault condition exists,

• There is no Current Diagnostic Trouble Code presently stored in the control module, and

• All the Tech 2 data parameters for that system, are within the normal operating range.

2.3 Diagnostic Precautions

The following precautions must be observed when performing all diagn osti c procedures. Otherwise, incorrect diagnostic

results or damage to system components will occur:

1 Disconnection of the battery affects certain vehicle electronic systems.

Refer to Section 00 Warnings, Cautio ns and Notes before disconnecting the battery.

2 Disconnect the battery negative lead when performing the following procedures:

• Disconnecting the electronic c ontrol module wiring harness conn ector/s or

• Charging the battery.

3 Disconnect the battery terminal ground lea d and the electronic control module wiring harness conn ector before

attempting any electric arc welding on the vehicle.

4 Do not start the engine if the battery terminal is not properly secured to the battery.

5 Do not disconnect or reconnect any of the following while the ignition is switched on or when the engine is running:

• Any electronic control module or system component el ectrical wiring connector, or

• Battery terminal leads.

6 Ensure that the correct procedure for disconnecting and co n necting system electrical wiring harness connectors is

always followed. For information on the correct procedure for disconnecting and connecting specific wiring

connectors, refer to Section 12P Wiring Diagrams .

7 Ensure that all wiring harness connectors are fitted correctly and secure.

8 When steam or pressure cleanin g vehicle components, such as engines, transmissions, etc., do not direct the

cleaning nozzle at any system electrical wiring harness connectors or compon ents.

9 Do not clear any DTCs unless instructed.

10 The fault must be present when usi ng the Diagnostic Trouble Code (DTC) Diagnostic Tables. Otherwise,

misdiagnosis or replacement of good parts may occur.

11 Do not touch any electronic control mo dule connector pins or soldered compon ents on the circuit board. This is

required to avoid the possibility of electrostati c discharge damage. Refer to Handling ESD Sensitive Parts,

4 Safety and Service Guidelines, in Section 00 Warnings, Cautions and Notes.

12 Use only the test equipment specified in the diagnostic tables, as other test equipment may give incorrect results or

damage good components.

13 Electronic control modules are designed to withstand normal curre nt draws associated with vehicle oper ation.

However, the following fault conditions or incorrect test procedure may overload internal control module circuits and

irreparably damage the control module:

• A short to voltage fault condition in any of the control module low reference circuits may cause i ntern al and/or

sensor damage. Therefore, any short to voltage fault condition in the control module low reference circuits

must be rectified before replacing a fau lty component.

• A short to ground fault condition in any of the control module 5 volts reference circuits may cause internal

control module and/or sensor damage. Therefore, any short to ground fault condition i n the control module 5

volt reference circuits must be rectified before replacing a faulty component.

• When using a test light to test an electrical circuit, do not use any of the control module low reference circuits

or 5 volts reference circuits as a reference point. Otherwise, excessive current draw from the test light may

damage the control module.

14 Disregard DTCs that set while performing the following diagnostic Steps:

• Using the Tech 2 output control function, or

• Disconnecting a control modu le system sensor connector then switching the ignition ON.

15 After completing the required diagnostics an d service operations, road test the vehicle to ensure correct system

operation.

2.4 Preliminary Checks

The Preliminary Checks is a set of visual and physical checks or inspections that may quickly identify a control module

system fault condition:

1 Refer to relevant Service Techlines for information regarding the fault condition.

2 Ensure that the battery is fully charged.

3 Inspect the battery connections for corrosion or a loose terminal.

4 Ensure that all relevant control module system related fuses are serviceable.

5 Inspect for incorrect aftermarket theft deterrent devices, lights or mobile phone i nstall atio n.

6 Ensure that there is no speaker magnet positi oned too close to any electronic module that contains relays.

7 Inspect the system wiring harness for proper connections, pinches or cuts.

8 Ensure that all control module related electrical wiring connectors are fitted correctl y.

9 Inspect the control module ground conn ections for corrosion, loose terminal or incorr ect position.

10 Ensure that the resistance between the control module housing and the b attery ground cable is less than 0.5 ohms.

11 Check that the control module and its mounting bracket is secure.

12 Check all control module relat ed components for correct installation.

13 Check the control module and related wiring harness routing to ensure that no rubbing or cutting of the wiring

harness by sharp body compo nents can occur.

3 Vehicle Diagnostics

3.1 Diagnostic System Check – Vehicle

Purpose of Test

When a vehicle system test is carried out, the following ‘Diagnostic System Check – Vehicle’ must be completed, using

Tech 2. This must always be the first stage in any diagnostic process before proceeding with a vehicle system specific,

diagnostic system check. Failure to complete this process, may lead to an incorrect or incompl ete dia gn osis of the

system fault or faults present in the vehicle.

When a vehicle system develops a fault, the source of the fault may not necessarily be located within the confines of the

system displaying a DTC. Accordingly, the follo wing ‘Diagnostic System Check – Vehicle’ table is provided to ensure that

any faults outside of a vehicle system that cause it to display a DTC, are id entified prior to any system specific diagnosis

being carried out.

When working through the Di agnostic System Check – Vehicle, once a referral is made, then that must be foll owed

through to its conclusion. It is not necessary to work through the complete Diagnostic Syst em Check – Vehicle table

before addressing the sec on d tiered level in the diagnostics strategy.

The order of control modules listed in this Diagnostic System Check is intent ional.

Test Description

The numbers below refer to the step numbers on the diagnostic table:

1 This step ensures that the battery, the vehicle primary power, and ground systems are functioning c orre ctly.

2 This test ensures that Tech 2 is being p owered up.

3 This step ensures that all mandatory Mo dules/ECU’s are present. Lack of communication with a mandator y

Module/ECU may be due to a particular malfunction of a serial data circuit.

4 Lack of communication may be due to a parti cular malfunction of a serial data circuit. You must be aware of the

vehicle options to determine if Tech 2 should be able to communicate with a Module/ECU or not.

5 This test step determines if the engine will crank.

6 This test step determines if the engine will start and idle.

7 This test step determines if any DTCs are present.

8/23 These steps ensure that DTCs are diagn osed in a specific order. With each step being linked to a unique

Diagnostic System Check, this appro ach provides quick access to the appropri ate Section.

NOTE

Not all the systems listed in this procedure are

fitted to all vehicles.

24 For specific symptoms complaints you shoul d refer to the associated system symptom diagnostics.

4 Diagnostic Trouble Code List –

Vehicle

Introduction

This master DTC list includes all applicable DTCs in numeric and alphanumeric order with descriptors. There will be

times when working through a diagnostic table, that you will be required to check for additi onal Diagnostic Trouble C od es

(DTCs). This list is intended to be used to identify those additional DT C/s and to provide a link to the appropriate

Diagnostic System Check table.

NOTES

• There are instances where the same

numerical DTC number is set by different

modules. Where this occurs, the DTCs are

listed in the same module order as listed in

the Diagnostic System Check – Vehicle.

• There are also multiple DTC listings that are

set by the same module. In these instances,

Tech 2 will identify the individual condition for

that item.

• Yet again, there are a number of DTCs with

the same descriptors that relate to different

vehicle systems; e.g. engines, transmissions

and braking system. Therefore, for this DTC

list to be of any value, you must be aware of

the vehicle equipment level and specification,

before activating the appropriate hyperlink.

Where a DTC has a letter prefix, it provides an indication of the system within the vehicle, that ‘owns’ that device. For
