Powertrain Control Module (PCM)

The powertrain control module (PCM) verifies that the password received from the theft deterrent module (TDM) 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 TDM.
• No passwords are received - there is no communication with TDM.
