Intermittent Operation of RKE System (Replace I/P Cluster)

This bulletin is being revised to update the parts information. Please discard Corporate Bulletin Number 00-08-52-004 (Section 8- Body and Accessories).

Some customers may comment that the remote keyless entry system fails to unlock all of the passenger doors when the key fob is pressed the second time.

This condition is intermittent.

Conflicting radio frequencies may cause a temporary logic lock-up of the remote keyless entry system.

1. Turn the ignition to the OFF position and remove the key from the lock.
2. Exit the vehicle and lock all the doors.
3. Wait at least 10 seconds.
4. From a distance greater than 3 m (10 ft) but less than 9 m (30 ft), press the unlock tab on the remote keyless entry transmitter. The driver's door will unlock. After waiting 1-2 seconds, depress the unlock tab the second time. The other doors should unlock.

If there is no response to the second key press, wait 30 seconds and depress the unlock tab again. If the doors unlock after the 30 second wait, disconnect the instrument cluster class 2 serial data wiring from the splice pack by completing the following additional steps:

4.1.	Remove the driver's side instrument panel sound insulator panel.





4.2.

Adjacent to the park brake assembly is a wiring harness approximately 24 mm (1 in) in diameter. The wiring harness will have a piece of white tape identifying the location of the splice pack. Remove enough of the wiring harness tape to separate the splice pack and remove the gray wire from cavity "G" of the splice pack.

5. Exit the vehicle and lock all of the doors.
6. Wait at least 10 seconds.
7. From a distance greater than 3 m (10 ft) but less than 9 m (30 ft), press the unlock tab on the remote keyless entry transmitter. The driver's door will unlock. After waiting 1-2 seconds, depress the unlock tab the second time. The other doors should unlock.
8. If the doors unlock at the command of the remote transmitter correctly, exchange the Instrument Panel Cluster with one obtained from an ACDelco® Service Center.
9. Place the gray wire back into cavity "G" and retape the wiring harness.
10. If the exchange cluster is not available for replacement at this time, reinstall the sound insulator panel.
11. Return the vehicle to the customer with the request to return the vehicle once the part is available.
12. When the exchange cluster becomes available, replace the Instrument Panel Cluster.

Refer to the Instrument Panel, Gauges and Console sub-section of the Service Manual for replacement procedures.

The following parts are available by contacting an ACDelco® Service Center.
