Condition

Some customers may comment that the backlighting on the IPC does not illuminate in the daylight hours. 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.

Correction

For customers who wish to have the IPC backlighting always illuminated, a new service calibration is now available that will activate the backlighting to full intensity during daytime hours. Reprogram the BCM using SPS.



GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

It cannot. However, take a copy of the bulletin to the dealer where you bought the car. It's a warranty item.
