- The code can be triggered by issues such as a faulty anti-theft module, wiring problems, a disconnected or damaged anti-theft module, or a communication error.

- Diagnosing the code typically involves using an OBDII scanner to retrieve the code, checking the wiring and connections to the anti-theft module, and testing the module itself for proper functioning.
