Theft Deterrent System

POWERTRAIN CONTROL MODULE (PCM)

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

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