Brake System Warning Light Comes on Intermittently (Reprogram IPC)
| Subject: | Brake System Warning Light Comes On Intermittently (Reprogram IPC) |
| Models: | 2005 Chevrolet Cobalt |
| 2005 Pontiac Pursuit (Canada Only) |
Condition
Some customers may comment that the brake system warning light comes on intermittently. The brake light will illuminate for 2 to 3 seconds, then will turn off and may never illuminate again. The vehicle should exhibit no braking concerns at all.
Correction
Important: Programming the IPC must be done PASS-THRU ONLY.
Inspect the brake fluid level and the operation of the parking brake signal switch. If normal, technicians are to reprogram the IPC with an updated software calibration. This new service calibration was released with TIS satellite data update version 6.5 available June 13, 2005. As always, make sure your Tech 2® is updated with the latest software version.
The customer should be thoroughly questioned to determine if a warning chime accompanies the brake system warning light, and if the BRAKE FLUID or PARKING BRAKE messages are displayed on the DIC when the condition occurs. The condition being discussed does not include any DIC message or warning chime. If the customer reports hearing the warning chime or the DIC messages, then further diagnosis is needed, searching for unwanted inputs from the parking brake switch signal or brake fluid switch signal.
