7. Troubleshooting
7.1 Common Issues and Solutions
- Door Lock Malfunction: If the remote door lock/unlock feature is not working correctly, it is crucial to verify all wiring connections. Incorrect identification or connection of vehicle wiring for door locks can lead to system malfunction. Consult your vehicle's specific wiring diagram and cross-reference with the provided MPC instructions.
- Remote Start Failure: Ensure your vehicle's battery is adequately charged. Confirm that the hood is closed, and the parking brake is engaged (if required by your vehicle's setup). Check all primary power and ground connections.
- Module Not Programming: Confirm that you are using two original factory keys for the programming process. Cloned or copied keys will not be recognized by the system for this step.
- General Electrical Issues: Always ensure all connections are secure, properly crimped, and insulated to prevent short circuits or intermittent functionality.
