2. Replace the BCM (if necessary)

   • Remove any components obstructing access to the BCM.
   • Unscrew the BCM from its mounting location and disconnect the wiring harness.
   • Install the new BCM by reversing the removal steps, ensuring all connections are secure.

4. Reprogramming (if applicable)
