Powertrain Control Module
Powertrain Control Module (PCM) contains the remainder of the logic of theft deterrent system. If a class 2 message containing a valid password is received from Passlock(tm) module, PCM will continue to allow fuel injectors to operate. PCM will allow fuel injectors to operate until it decides there is no valid password coming from Passlock(tm) module. If PCM does not receive a class 2 message, or receives a class 2 message with an incorrect password, engine will crank and will not run or will start and stall immediately.
