Instruments - Gauge Needles Sweep When Using OnStar(R)

Bulletin No.: 07-08-49-026

Date: December 04, 2007

TECHNICAL

Subject:
Instrument Panel Cluster (IPC) Performs A Running Reset/WOW During OnStar Usage (Reprogram IPC)

Models:
2008 HUMMER H2

Attention:
This service bulletin applies to IPC part numbers 25862694 and 25862695 only.

Condition

Some customers may comment that the Instrument Panel Cluster performs a running reset or WOW display during OnStar(R) usage. The customer may notice that the IPC will momentarily sweep the gauge pointers to zero (home position) and illuminate all the telltales as if they had started their vehicle. The IPC does return to normal operation after the WOW.

Correction





A revised calibration has been developed to address this condition. Technicians are to reprogram the IPC using SPS with the latest software available on TIS2WEB. Refer to the Service Programming System procedures in SI. As always, make sure your Tech 2(R) is updated with the latest software version.
