CAUTION: 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 checked and/or the donor vehicle.
NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.

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

To place the cluster in engineering test mode (ETM) carry out the following steps
1. Press and hold the stalk trip cycle button, for more than five seconds but less than eight seconds, whilst briefly pressing the
vehicle START button. There is no initial display indication that the instrument cluster has entered ETM. If ETM has successfully
been entered then 'ENGINEERING TEST MODE' will be displayed in the Message Centre when the stalk trip button is released .
2. To navigate forward through the instrument cluster Self-Diagnostic Mode tests, press the stalk trip cycle button.
3. Each push of the stalk trip cycle button will advance one step through the ETM sequence. It is not possible to move
backward through the test sequence.
4. To exit the Self-Diagnostic Mode press and hold the stalk trip cycle button for more than three seconds.
5. The Self-Diagnostic Mode is also deactivated when the ignigition switch is turned to the 'OFF' position or low battery voltage
is detected.
