WARNINGS: Cleaning

Do not carry out any repairs to the fuel system with the engine running. Failure to follow this instruction may result in
personal injury.


Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


If fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek immediate medical attention.


Place the vehicle in a well ventilated, quarantined area and arrange ' No Smoking/Petrol Fumes' signs about the vehicle.


Wash hands thoroughly after fuel handling, as prolonged contact may cause irritation. Should irritation develop, seek
medical attention.


Do not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors
are always present and may ignite. Failure to follow these instructions may result in personal injury.
CAUTIONS:


Before using the cleaning fluid, protect all electrical components and connectors with lint-free non-flocking material.
Make sure that all parts removed from the vehicle are placed on the lint-free non-flocking material.
Make sure that any protective clothing worn is clean and made from lint-free non-flocking material.


Make sure that clean non-plated tools are used. Clean tools using a new brush that will not lose its bristles, prior to
starting work on the vehicle.


Use a steel topped workbench and cover it with clean, lint-free non-flocking material.


Make sure the workshop area in which the vehicle is being worked on is as clean and as dust free as possible. Foreign
matter from work on clutches, brakes or from machining or welding operations can contaminate the fuel system and may result
in later malfunction.

1. Using a new brush that will not lose its bristles, brush the components
being removed and the surrounding area.

2. Using a pneumatic vacuum gun, remove all traces of foreign material.

Symptom Possible Cause Action No throttle response
Electronic engine controls
Read DTCs and refer to DTC Index in this
section for electronic engine control tests Speed control inhibited or disabled
Default mode enabled
Speed control, brake switch
Electronic engine controls
CAN fault
Check message center for default message,
read DTCs and refer to DTC Index
Refer to the relevant section of the
workshop manual for speed control, and
brake switch tests.
Read DTCs and refer to DTC Index in this
section for electronic engine control tests
Refer to the relevant section of the
workshop manual and the electrical wiring
diagrams to perform CAN network tests. Poor throttle response
Breather system
disconnected/restricted
Electronic engine controls
Transmission malfunction
Traction control event
Air leakage
Ensure engine breather system is free from
restriction and is correctly installed
Read DTCs and refer to DTC Index in this
section for electronic engine control tests
Refer to the workshop manual or
transmission troubleshooting guide for
transmission system tests.
Check for leakage in air intake system Engine defaults, warning light and
messages. Refer to the owner
handbook
Electronic engine controls
Read DTCs and refer to DTC Index in this
section for electronic engine control tests DTC Index


WARNING: Fuel injector voltage will reach 65Volts during operation and have a high current requirement.


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the module/component is suspect and the vehicle remains under the Manufacturers warranty, refer to the Warranty
Policy and Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer-approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

DTC Description Possible Causes Action B10A2-31 Crash Input - No signal
Loss of communication between
Restraints Control Module (RCM)
and Engine Control Module
(ECM) Refer to the electrical circuit diagrams and
check Restraints Control Module (RCM) Pulse
Width Modulated (PWM) SRS signal line circuit,
hard wired connection between Engine Control
Module (ECM) and Restraints Control Module
(RCM) for short to ground, short to power, open
circuit. Repair circuit as required, clear DTC and
retest system to confirm repair.

Refer to: Catalytic Converter LH (309-00C Exhaust System - V8 5.0L Petrol/V8 S/C 5.0L Petrol, Removal and Installation).

25. Refer to: Catalytic Converter RH (309-00C Exhaust System - V8 5.0L Petrol/V8 S/C 5.0L Petrol, Removal and Installation).

26. Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

27. Check and top up the cooling system as required.

28. Set the heater controls to HOT.


29. CAUTION: Observe the engine temperature warning light. If the
warning light is displayed, switch off immediately and allow to cool.
Failure to follow this instruction may cause damage to the vehicle.

Start the engine and allow to idle until hot air is emited at the face
registers.

30. CAUTION: Observe the engine temperature warning light. If the
warning light is displayed, switch off immediately and allow to cool.
Failure to follow this instruction may cause damage to the vehicle.

Raise the engine speed to 2000 RPM and maintain at 2000 RPM until the
engine cooling fan operates.


31. CAUTION: Switch off the engine and allow the coolant temperature
to go cold.
Switch the engine off and allow to cool.

32. Visually check the engine and cooling system for signs of coolant
leakage.

33. WARNINGS:


When releasing the cooling system pressure, cover the coolant
expansion tank cap with a thick cloth.


Since injury such as scalding could be caused by escaping steam or
coolant, make sure the vehicle cooling system is cool prior to carrying
out this procedure.
CAUTIONS:


Make sure the coolant level remains above the "COLD FILL RANGE"
lower level mark.


Anti-freeze concentration must be maintained at 50%.


NOTE: When the cooling system is warm, the coolant will be
approximately 10mm above the upper level mark on the expansion tank
with the cap removed.
Check and top-up the coolant if required.

34. Refer to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L
Petrol, General Procedures).
