| Subject: | Backlighting on Driver and Passenger Door Switches Remains On, High Parasitic Current Draw Occurs (Replace HTR & A/C Programmer Asm [Instrument Panel Module]) |
| Models: | 2000-2002 Buick LeSabre Limited (Built Prior to VIN Breakpoint 2U132314 -- Hamtramck Plant) |
| 2001-2002 Oldsmobile Aurora (Built Prior to VIN Breakpoint 24130554) |
| 2000-2002 Pontiac Bonneville (Built Prior to VIN Breakpoint 24130554) |
| With RPO CJ2 |
Condition
Some customers may comment on the following:
| • | The vehicle is parked and locked and sits for a minimum of 3.5 minutes. Current draw on the battery is approximately 20 milliamperes. |
| • | The Remote Keyless Entry (RKE) trunk unlock button is depressed and the trunk is opened and closed again within 10 seconds. |
| • | The door panel backlighting for the power door locks, power windows, O/S mirror control, passenger temperature control, memory and heated seat switches remains on. Current draw on the battery is now approximately 720 milliamperes. |
| • | The backlighting remains on until the RKE door lock or unlock button is activated. |
Cause
This high parasitic current draw on the battery may be due to a unique software issue within the Instrument Panel Module (IPM), also referred to as the HTR & A/C Programmer Assembly.
Correction
Modifications have been made to the IPM software.
- Replace the IPM, described as the HTR & A/C Programmer Assembly in Parts Information. Refer to the Body Control System sub-section in the Service Manual for replacement procedures. Refer to the following chart for replacement procedures within SI2000.
