Passlock(tm) Module
The Passlock(tm) module contains the theft deterrent system logic. The Passlock(tm) module reads the Passlock(tm) data from the Passlock(tm) sensor. The Passlock(tm) module will determine the validity of the Passlock(tm) data. If the Passlock(tm) data is correct, the Passlock(tm) module will pass theft. The Passlock(tm) module will then transmit the code password to the VCM/PCM. (Scheme 32) When the VCM/PCM receives the correct code the VCM/PCM allows the fuel injectors to operate normally.
During the tamper mode the vehicle may start. The vehicle will quickly stall. If the Passlock(tm) module receives the wrong Passlock(tm) data, the anti-theft will immediately go into the tamper mode. The tamper mode will lock-out the vehicle fuel injectors for 10 minutes. The SECURITY indicator will flash while the anti-theft is in the tamper mode.
If the Passlock(tm) sensor sends a correct password to the Passlock(tm) module when the ignition is in the ON position, the Passlock(tm) module will send a fuel enable signal to the VCM/PCM. The VCM/PCM will not disable the fuel due to any Passlock(tm) module message for the remainder of the ignition cycle.
