Theft Deterrent

POWERTRAIN CONTROL MODULE (PCM)

The PCM verifies that the password received from the theft deterrent control module via the serial data circuit is correct. The PCM can learn only one fuel continue password. If the fuel continue password is correct, the PCM enables the starting and fuel delivery systems.

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