Subject: Instrument Panel Cluster (IPC) Backlighting Inoperative During Daylight Hours (Reprogram BCM) #06-08-49-016B - (09/12/2006)
2005-2006 Pontiac G6
Condition
Some customers may comment that the backlighting on the IPC does not illuminate in the daylight hours with headlamps manually turned on. They may further state that the backlighting does function at night, but not in the day time.
Cause
On these vehicles, backlighting for the IPC is not enabled unless the vehicle's lighting photocell determines that there is a nighttime ambient condition. Backlighting is not controlled through the use of the park lamp or headlamp switch. The conditions under which the photocell activates the backlighting may not satisfy each particular customer’s personal expectations, or the customer may simply prefer to have the backlighting always illuminated on the IPC when headlamps are manually turned on.
Correction
Important: Module reprogramming must be done using the Pass-Thru method. Select "Instrument Panel (Backlight Dimming Fix ONLY)" from the Supported Controllers list.
For customers who wish to have the IPC backlighting illuminated, a new service calibration is now available that will activate the backlighting to full intensity during daytime hours with headlamps manually turned on. Reprogram the BCM using SPS. The new calibrations are currently available on TIS2WEB.
