^ The EVO/PASSLOCK module is reading a tamper code form the PASSLOCK sensor for longer than 1.0 second.

ACTION TAKEN WHEN THE DTC SETS
^ The vehicle will not run. The security telltale will be flashing.
^ The PASSLOCK state is Tamper.

CONDITIONS FOR CLEARING THE DTC
^ The DTC will clear after an ignition cycle has occurred without the fault.
^ EVO/PASSLOCK module history codes will be cleared after 100 ignition cycles with no current codes active.
^ Using a scan tool.
