  3. Inspect the BCM for Damage: Physically check the BCM for any signs of damage, such as corrosion, water intrusion, or burnt components.
  4. Test the BCM: Use a multimeter or specialized diagnostic tools to test the BCM’s inputs and outputs. This will help verify whether the module is functioning correctly.
  5. Consult a Professional: If you’re unsure about any of these steps, consult a qualified automotive technician specializing in electrical systems.

Why is it important to check the fuses first? A simple blown fuse can cause similar symptoms to a faulty BCM and is a much cheaper and easier fix.
