Powertrain Control Module (PCM)

The PCM verifies that the password received from the theft deterrent control module. The theft deterrent control module can learn only one fuel enable password. If the fuel enable password is correct, the PCM enables the fuel delivery systems.

The PCM disables the fuel delivery systems if any of the following conditions occur:
- The enable password is incorrect.
- The system disable password is sent by the theft deterrent control module.
- No passwords are received - there is no communication with the theft deterrent control module.
