Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a safe working environment and the engine is off.

2. Battery Check

Tools Required: Multimeter
Disconnect the negative battery terminal.
Measure the battery voltage; it should be above 12.4 volts.
If the voltage is low, charge or replace the battery as necessary.

3. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the BCM.
Look for frayed wires, broken connections, or signs of corrosion.
Repair or replace any damaged wiring or connectors.

4. Fuse Inspection

Tools Required: Fuse puller or flathead screwdriver
Open the fuse panel and check the fuses associated with the BCM.
Replace any blown fuses with the correct amperage rating.

5. BCM Testing

Tools Required: Multimeter, scan tool
Reconnect the battery terminal.
Use a multimeter to test the power and ground circuits to the BCM.
If power is present, but the BCM is non-responsive, it may need replacement.

6. Replace BCM (if necessary)

Tools Required: Socket set, trim removal tools
Disconnect the battery again.
Remove the BCM from its mounting location.
Install the new BCM and reconnect all wiring harnesses.
Reconnect the battery.
