Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the ignition is turned off.
• Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Wiring and Connectors

• Remove any components obstructing access to the BCM wiring harness.
• Visually inspect the wiring harness and connectors for signs of wear, corrosion, or damage.
• Use a multimeter to check the voltage on the BCM connectors (should be around 12V with ignition on).

3. Test the Body Control Module

• If wiring is intact, reconnect the battery terminal and turn the ignition to the ON position without starting the engine.
• Use a scan tool to check the BCM for any stored codes or malfunctions.
• If the BCM is unresponsive, consider replacing the BCM with a compatible module.

4. Replace Key Fob Battery

• Open the key fob using a small flathead screwdriver.
• Replace the old battery with a new one (ensure the correct type, typically CR2032).
• Reassemble the key fob and test its functionality.

5. Check and Replace Fuses

• Locate the fuse box and check the fuses related to the BCM and security system.
• Replace any blown fuses with new ones of the same amperage.
