Subject:
Various Electrical Concerns - Hood Open Message Displayed, Systems Inoperative: Door Locks, Windshield Wiper/Washer, Trunk Release, Courtesy Lamps, (Replace BCM and Install Connector Service Kit)
Models:
2006 Chevrolet Impala, Monte Carlo
Condition
Some customers may comment on various electrical concerns. Some of the conditions that may be present are:
Hood Open Message Displayed in DIC When Hood Is Closed
Door Locks Inoperative
Windshield Wiper/Washer Inoperative
Trunk Release Inoperative
Dome and Courtesy Lamps Inoperative
Cause
These conditions may be due to the engine cooling fans inducing a voltage spike that causes internal damage to the BCM.
Correction
Replace the BCM and install connector service kit, P/N 25777448, at the BCM to prevent these conditions from reoccurring.
Remove the push pin retainers and the left side closeout/insulator panel.
Remove the retaining screws and the steering column opening filler panel.
Remove the retaining bolts and the driver knee bolster.
Disconnect the BCM connectors.
Remove the BCM from its mounting bracket.
Install the new BCM to its mounting bracket.
Remove the BCM wiring harness clip to allow for slack.
Install diode # 1.
Locate BCM connector C4 (black). Open the harness by removing the tape.
Locate the pink/black wire, circuit 109, connector pin 17.
Cut the wire approximately 25 mm (1 in) up from the connector end.
Splice in the diode using the supplied duraseal splice sleeves. Red lead wire (+) goes toward the BCM.
Shrink the insulation around the splice using a heat torch.
Tape the diode to the harness using electrical tape. Install diode # 2.
Locate BCM connector C5 (brown).
Open the harness by removing the tape.
Locate the purple wire, circuit 5531, connector pin 15.
Cut the wire approximately 25 mm (1 in) up from the connector end.

Tighten
Tighten the bolts to 2 N.m (18 lb in).
Install the steering column opening filler panel and retaining screws.
Tighten
Tighten the bolts to 2 N.m (18 lb in).
Install the left side closeout/insulator panel and push pin retainers.
Program the BCM. Refer to the Body Control Module (BCM) Programming/RPO Configuration in SI.
