Starting System - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Starting
System Vehicles With: Smart Key
Diagnosis and Testing

Principles of Operation Published: 06-Apr-2013

For a detailed description of the starting system, refer to the relevant Description and Operation section in the workshop
manual.

Inspection and Verification

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection
Mechanical Electrical
Steering column
Brake pedal
Smart key
Steering Wheel
Fuses
Harnesses and connectors
Warning lamp operation
Smart key operation
Engine start operation
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTC's) and refer to the DTC Index.

5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSM's which may be valid for the specific
customer complaint and carry out the recommendations as needed.
CAUTIONS:


Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle


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 control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures 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 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


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


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes 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

Symptom Chart
Symptom - Message Displayed Symptom - Possible Cause Action Smart key not found - Refer to handbook Ignition mode fails to switch on GO to Pinpoint Test A.

Symptom - Message Displayed Symptom - Possible Cause Action NOTE: Back up start - 10MY onwards
Smart key not found - Refer to handbook Ignition mode fails to switch on GO to Pinpoint Test B. Press start and brake Engine fails to crank GO to Pinpoint Test C. Steering column locked Ignition switches off after 3 seconds GO to Pinpoint Test D. NOTE: For diesel engines Engine still not cranking Ambient temperatures below zero GO to Pinpoint Test E.
Pin Point Test

PINPOINT TEST A : SMART KEY NOT FOUND - REFER TO HANDBOOK TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: IGNITION MODE FAILS TO SWITCH ON NOTES:


In normal operation, pressing the start button for one second will cause the vehicle to enter the ignition mode. If the
procedures below are followed the engine should crank
For automatic transmission vehicles, ensure the brake pedal is depressed and the park or neutral selected 1 Ensure the smart Key is within the cabin area. Check the smart key is not close to any electrical devices e.g. Smart phones, laptops, laptop cases, games consoles and game console bags, briefcases, metal
objects etc. All can affect the system performance and may block its communication with the vehicle. If
the smart key battery low warning message has been displayed it is likely that the smart key battery has
insufficient charge. Refer to section 'Back Up Start' for 10MY onwards Has the vehicle started? Yes
No further action required
No
Check and install a new battery as required. Clear the DTC and retest. If the problem persists, contact
dealer technical support
PINPOINT TEST B : BACK UP START - 10MY ONWARDS - SMART KEY NOT FOUND - REFER TO HANDBOOK TEST
CONDITIONS DETAILS/RESULTS/ACTIONS B1: IGNITION MODE FAILS TO SWITCH ON NOTES:


In normal operation, pressing the start button for one second will cause the vehicle to enter the ignition mode. If the
procedures below are followed the engine should crank
For automatic transmission vehicles, ensure the brake pedal is depressed and the park or neutral selected 1 On pressing the start button, smart key not found. When this warning is displayed the smart key should be brought into close proximity with the immobilize antenna unit. Hold the key in the location and press
the start button again. If this process fails the first time, try repositioning the key around the immobilize
antenna unit location, repeat the sequence again Has the vehicle started? Yes
No further action required
No
Contact dealer technical support
PINPOINT TEST C : PRESS START AND BRAKE - (MESSAGE DISPLAYED) TEST
CONDITIONS DETAILS/RESULTS/ACTIONS C1: ENGINE FAILS TO CRANK NOTES:


Conditions for starting in addition to pressing the start button are

PINPOINT TEST D : STEERING COLUMN LOCKED - (MESSAGE DISPLAYED) TEST
CONDITIONS DETAILS/RESULTS/ACTIONS D1: IGNITION SWITCHES OFF AFTER 3 SECONDS NOTES:


Conditions for starting in addition to pressing the start button are
For automatic transmission vehicles, ensure the brake pedal is depressed and the park or neutral selected
If the engine can be heard to crank there is no fault with the smart key
If the locking pin is still engaged, turn the steering wheel to overcome the side load
Start authorisation defined as Ignition functions, Steering column lock engagement, Engine immobilize and smart key
authorisation 1 Unlock the vehicle using the key fob, within 3 minutes of unlocking ensure the steering wheel can rotate freely. Perform a further lock and unlock check and attempt to start vehicle. If the steering 'column locked'
message is still displayed, Lock the vehicle with the key fob and ensure the column is locked (If
installed) by turning the steering wheel. Then unlock the vehicle ensuring the column Steering wheel can
turn freely. Now perform another start attempt Did the engine start?
Yes
No further action required
No
Contact dealer technical support
PINPOINT TEST E : ENGINE STILL NOT CRANKING TEST
CONDITIONS DETAILS/RESULTS/ACTIONS E1: AMBIENT TEMPERATURES BELOW ZERO 1 Hold the start button down for at least 4 seconds while starting the vehicle 2 Switch the ignition on, the passive anti theft system (PATS) LED should now be illuminated. Start the engine, the PATS LED should switch off after 3 seconds Did the engine start? Yes
No further action required
No
