Passlock (TM) Module

The Passlock TM/EVO module contains the theft deterrent system logic. The Passlock TM/EVO module reads the Passlock(TM) data from the Passlock(TM) sensor. If the Passlock(TM) data is correct, the PASSLOCK TM/EVO module will pass theft. The Passlock(TM)/EVO module will then transmit the code password to the VCM.

During the tamper mode the vehicle may start. The vehicle will quickly stall. If the Passlock(TM)/EVO module receives the wrong Passlock(TM) data, the VTD 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 VTD is in the tamper mode.

If the passlock sensor sends a correct password to the passlock/EVO module when the ignition is in the ON position, the passlock/EVO module will send a fuel enable signal to the VCM. The VCM will not disable the fuel due to any passlock module message for the remainder of the ignition cycle.
