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 VIN 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 message center displays internal data that can be cycled through. All other functions will continue to operate normally, unless otherwise noted.

ETM text is not language configurable and will be displayed in English.

NOTE:
The information provided in this bulletin utilizes the ETM messages displayed in conjunction with IDS to diagnose IC concerns. The information provided in this bulletin does not supersede or replace the IDS facility.

NOTE:
ETM can be exited by pressing the stalk trip cycle button for more than 3 seconds. ETM can also be deactivated when the ignition switch is placed in 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 XK 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:

NOTE:
There is no display to initially indicate that the IC has entered ETM. Access to ENGINEERING TEST MODE is confirmed only after the stalk trip cycle button has been released and the message ENGINEERING TEST MODE then displays in the message center.

^ Press and hold the stalk trip cycle button for more than 5 seconds but less than 8 seconds while briefly pressing the START button.

^ Release the stalk trip cycle button before 8 seconds has elapsed.

^ Verify ENGINEERING TEST MODE is displayed in the message center after the stalk trip cycle button has been released.

4. If ENGINEERING TEST MODE does not display in the message center, re-attempt access to ETM by repeating step 3 paying particular attention to sequence timing.

NOTE:
It is not possible to move backward through the ETM test sequence. Each push of the stalk trip cycle button will advance one step through the ETM sequence.

5. Navigate forward through the IC ETM test sequence by pressing the stalk trip cycle button.

6. After all tests have been completed, exit ETM by pressing the stalk trip cycle button for more than 3 seconds or by placing the ignition in the OFF position.
