Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, electrical tape.
Disconnect the negative battery terminal to prevent any electrical shorts or shocks.

2. Inspect and Replace Fuses

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the fuse related to the BCM and lighting system using a fuse puller.
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinstall the new fuse and ensure it is seated properly.

3. Check Wiring and Connectors

Visually inspect the wiring harness connected to the BCM and lighting system for signs of wear, fraying, or corrosion.
Use a wire brush to clean corroded connectors and ensure a good electrical connection.
Reseat any loose connectors and secure them with electrical tape if necessary.

4. Test BCM Functionality

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the B1630 code.
Start the vehicle and monitor the BCM operation and lights.
Use a multimeter to verify the voltage at the BCM connectors; it should match the specifications listed in the service manual.

5. Reprogram BCM (if necessary)

If the issue persists, the BCM may need to be reprogrammed or replaced.
Follow the manufacturer’s instructions for BCM reprogramming, which may require a special diagnostic tool or software.
