  1. Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
  2. Use the OBD-II scanner to access BCM data and check for any active or pending codes.
  3. If B1000 persists, perform a BCM test using the multimeter to check for proper voltage and ground connections.
  4. If malfunctioning, replace the BCM according to manufacturer specifications.

5. Clear Codes and Test Drive
