Solution

1. Preparation

Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check BCM Connections

Locate the Body Control Module, typically found under the dashboard or behind the glove box.
Remove any panels obstructing access to the BCM.
Disconnect the BCM connector and inspect for any bent pins, corrosion, or dirt.
Clean the connector with electrical contact cleaner and reconnect securely.

3. Inspect Wiring Harness

Follow the wiring harness from the BCM to the affected components (e.g., lights, locks).
Look for abrasions, frays, or breaks in the wiring.
Repair any damaged wiring using solder and heat-shrink tubing or electrical tape.

4. Test Power and Ground

Use a multimeter to check for proper voltage at the power feed to the BCM.
Test the ground connection for continuity.
If either is faulty, trace back to the source and repair as necessary.

5. Reprogram or Replace BCM (if necessary)

If the BCM is determined to be faulty, use a compatible scan tool to reprogram the new BCM according to the manufacturer's specifications.
Follow the installation instructions for the new BCM, ensuring all connections are secure.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and monitor for the return of the B10 code.
Check all previously affected systems (lights, windows, locks) to ensure proper operation.
