AFFECTED VEHICLE RANGE:

CONDITION SUMMARY:

ADDITIONAL DIAGNOSTIC PROCEDURES TO RESOLVE INSTRUMENT CLUSTER CONCERNS

Situation:
This information only bulletin is being issued to provide additional diagnostic procedures to resolve Instrument Cluster (IC) concerns. The additional diagnostic information is intended to reduce the number of components being returned under Warranty with no fault found (NFF).

Action:
Should a customer express an Instrument Cluster concern, refer to the Repair Procedures detailed in this bulletin to diagnose and resolve the concern.

PARTS:

No parts required. Diagnostic information only.

TOOLS:

Integrated Diagnostic System (IDS)

WARRANTY:

Diagnostic information only. Normal warranty policy and procedures apply.

REPAIR PROCEDURE

DIAGNOSE INSTRUMENT CLUSTER CONCERNS USING ENGINEERING TEST MODE (ETM) AND

INTEGRATED DIAGNOSTIC SYSTEM (IDS)

NOTE:
The Instrument Cluster (IC) installed from the start VINs listed above contains a self- diagnostic feature known as Engineering Test Mode or ETM. The ETM can display the status of IC inputs as well as providing a number of other useful features.

When in ETM, the right-hand message center or the single LCD displays internal data that can be cycled through; the left-hand message center functionality remains unaffected, with some exceptions, during ETM.

NOTE:
The information provided in this bulletin utilizes the ETM messages displayed for a specific model in conjunction with IDS to diagnose IC concerns. The information provided in this bulletin does not supersede or replace the IDS facility. If ETM is not available, IDS alone is to be used to diagnose the Instrument Cluster concerns.

NOTE:
When activating ETM, the stalk trip cycle button must be released within 3 seconds after "ENGINEERING TEST MODE" has been displayed or the IC will automatically exit ETM. ETM will also be deactivated when the ignition switch is turned to the "OFF" position or low battery voltage is detected.

1. Refer to the "Area of Issue" and "Notes" listed in Table 1 that identify each of the customer concerns.

2. Perform each of the "Actions" listed for the identified "Area of Issue", in succession, referring to the relevant model's ETM Table, as required, to complete the "ETM Test No." specified.

3. Before performing an ETM test, place the vehicle cluster in the self-diagnostic Engineering Test Mode (ETM) as follows:

^ Press and hold the stalk trip cycle button while turning the ignition from position "0" to position "II" until "ENGINEERING TEST MODE" is displayed on the RH message centre.

^ Release the stalk trip cycle button before 3 seconds has elapsed.

4. If ETM can not be accessed, repeat step 3 paying particular attention to sequence timing.

5. If ETM still can not be accessed, check for correct function of the stalk buttons.

6. If ETM still can not be accessed, use IDS to diagnose the IC.

7. Navigate forward through the ETM tests by pressing the trip computer "MLS/KMS" button.

8. Navigate backward through the ETM tests by pressing the trip computer "A/B" button.

9. After all tests have been completed, exit ETM by pressing the stalk trip cycle button for more than 3 seconds or by turning the ignition switch to the OFF position.
