1 General Description
1.1 General Information
There are a number of reasons for including this Section in the MY 2005 Service Information:
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 (GMLAN) for HFV6 V6 and GEN IV V8 engines.
Vehicle Diagnostics Page 0D – 3
Page 0D – 3
Figure 0D – 1 – V6 Serial Data Communications
2 A Powertrain Interface Module (PIM) is required as the hardware and serial communications interface for both the
V6 and GEN IV V8 engines. With V6 engines, the GMLAN PIM acts as a transparent bi-d irectional translation
device that allows data to flow between modules with GMLAN protocol and modules with UART protocol (see
Figure 0D-1). With GEN IV V8 engines, the GMLAN PIM also acts as a transparent bi-directional translation device
that allows data to flo w bet ween mod ules with GMLAN protocol and modules with UART protocol (see Figure 0D-2)
3 With the communication necessary between the V6 engine and transmissi on 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 structured approach to the diagno stic process for electrical systems within the vehicle is most important.
Vehicle Diagnostics Page 0D – 4
Page 0D – 4
Figure 0A – 2 – GEN IV V8 Serial Data Communications
The Body Control Module (BCM) is the UART ‘Bus Master’ that periodically polls (or surveys) each of the following
devices on the serial data bus every 300 milliseconds (incl uding the BCM itself), requesting status data. Exceptions are
the PIM and the Audio Head Unit (AHU), which are polled every 150 milliseconds:
• V6 Engine Control Module (ECM) and Transmission Control Modu le (TCM), via the GMLAN PIM.
• GEN IV V8 Engine Control Module (ECM) and AWD ABS / TCS, via the GMLAN PIM.
• V6 ABS/TC/ESP via the GMLAN PIM.
• GEN IV V8 RWD ABS/TCS via the GMLAN PIM.
• Instrument cluster (INS).
• Occupant Climate Control (OCC) Module.
• Audio System Head Unit (AHU).
• Supplemental Restraint System (SRS) Sensing Diagnostic Module (SDM).
• Body Control Module (BCM)
• Tech 2 diagnostic scan tool.
Vehicle Diagnostics Page 0D – 5
Page 0D – 5
While there are other modules and devices connected to the serial data bus, they only monitor the bus for applicable
data that affects their functionality. These devices are:
• Telematics Control Module.
• Audio Interface Module (AIM).
• Digital Video Disc (DVD).
• Premium Sound Amplifier (PSA).
• Memory Seat and Mirror Module (MSM).
• Multi Function Display (MFD) via the AHU.
• Tyre Pressure Monitor.

1.2 The Diagnostic Strategy
Resulting from the increased compl exity and communication s systems utilised in MY 2005 range of vehicles, this three
staged approach to the diagnostic process must be undertaken in the specified ma nner, 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.
Vehicle Diagnostics Page 0D – 7
Page 0D – 7
Symptom Diagnostics
Should all of the following conditions exist, refer to the Symptom Tables, that may be provided for a particular system:
• A 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.
Vehicle Diagnostics Page 0D – 8
Page 0D – 8
2 Diagnostic Skills Required
2.1 Basic Knowledge Required
A lack of basic understanding regarding
electronics, electrical wiring circuits and use
of electrical circuit testing tools when
performing any diagnostic procedure, could
result in incorrect diagnostic results or
damage to system components.
Understanding of the following is required to perform any of the dia gn ostic procedures detailed in this Service
Information:
• Basic electronics,
• Electrical wiring circuits,
• Electrical circuits testing, and
• Correct use of basic system diagnostic tools.
Refer to Section 12P Wiring Diagrams and to 2.2 Basic Diagnostic Tools Required, as required.
In addition, a complete under standing of the affected vehicle system is essential to prevent misdiagnosis and component
damage. Refer to 1.1 General Information in any specific Section.
Vehicle Diagnostics Page 0D – 9
Page 0D – 9
2.2 Basic Diagnostic Tools Required
Use of incorrect electrical circuit diagnostic
tools when performing any diagnostic
procedures could result in incorrect
diagnostic results or damage to system
components.
The following electrical circuit testing tools are required to perform the diagnostic procedu r es detailed in this Section.
• Tech 2, refer to Section 0C Tech 2.
• Unpowered test lamp, refer to Section 12P Wiring Diagrams.
• Digital multimeter with a minimum 10 Megohm impedance, refer to Section 12P Wiring Diagrams.
Vehicle Diagnostics Page 0D – 10
Page 0D – 10
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, Cautions and Notes
before disconnecting the batter y.
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 Harness, Connectors.
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 possib ility of electrostatic discharge damage. Refer to Hand ling ESD Sensitive Parts, 4 Safety
and Service Guidelines, in Section 00 Warni ngs, 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.
Vehicle Diagnostics Page 0D – 11
Page 0D – 11
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 nstallation.
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’ has to be completed, using
Tech 2. This must always be the first stage in any diagnostic process before proceeding with a vehicle s ystem 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 ond level in the diagnostics strategy.
The order the control modules are listed in this Diagnostic System Check, is intentio nal.
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.
8/24 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.

3.2 DTC Symptom Description
A DTC symptom code is a 2-digit number which adds a dditional detail to a DTC. The DTC symptom provides additi onal
information without requiring a large increase in the number of new DTCs.
DTC Symptom Categories
The DTC symptom code is made up of 2 alphanumeric digits. The first digit following the DTC indicates the DTC
symptom category. There are 16 possible categories available in the range of 0 throug h the letter F . Currently there are
8 categories in use, 0 through 7. These 8 categories together with their de f initions are given below.
Category
Number Category Name Category Description
0 General Electrical Failures This category includes standard wiring failure modes, direct current
quantities related by Ohm's Law and quantities related to amplitude,
frequency or rate of change, and wave shape.
1 Additional General Electrical
Failures This category includes the overflo w from the previous category.
2 FM/PWM (Frequency/Puls e
Width Modulated) Failures
This category includes faults related to frequency modulated and pulse width
modulated inputs and outputs of the electronic control module (ECU). This
category also includes faults where position is determined by counts.
3 ECU Internal Failures This category includes faults related to memory, software, and internal
electrical circuitry; requiring ECU replacement.
4 ECU Programming F ailures This category includes faults related to operational software, calibrations,
and options, remedied by programming the ECU.
5 Algorithm Based Failures This category includes faults based on com paring two or more input
parameters for plausibility or comparing a single paramet er to itself with
respect to time.
6 Mechanical Failures This category includes faults detected b y inappropriate motion in response to
an ECU controlled output.
7 Bus Signal/Message Failures This category includes faults related to bus hardware and signal integrity.
This category is also used when the ph ysical input for a signal is located in
one ECU and another ECU diagnoses th e circuit.
8-F Reserved by Document Not in use at this time.
DTC Symptom Sub-types
The second digit of the DT C symptom code is the subtype of the DTC symptom. These subtypes and t heir categories,
together with their definitions, are give n in the following table, except for DTC symptom ‘00’, which is a special case. If
‘00’ is displayed, only the base DTC code nu mber and its description apply. Information regarding the fault will be
provided in the code setting criteria.
Example
The DTC symptoms associated with each DTC provide more information about the fault that caused that DTC. An
example of a DTC displa yed can be C0050 05, where the ‘C0050’ is the DTC, and ‘05’ after the space represents the
DTC symptom. While this DTC indicates that the fault is in the Right Rear W heel Speed Sensor, the DTC symptom ‘05’
indicates the circuit is shorted to battery or open. Another possible symptom for this code is C0050 0F, where ‘C0050’ is
the DTC for the Right Rear Wheel Spee d Sensor, and ‘0F’ indicates that the sensor signal is erratic.

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 Cs 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 of the
same number, that are set by the same
module. In these instances, the symptom
code is also listed. Tech 2 will identify both
the DTC, the individual symptom code and a
description 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
