Passlock™ Data Voltage : The scan tool displays the voltage code from the Passlock sensor to the Body Control module (BCM). A valid Passlock sensor voltage of 5 volts will be displayed on the scan tool when the ignition cylinder is turned to the on position. Once the ignition cylinder has been rotated to the crank position the Passlock voltage will drop from 5 to 0.86-4.28 volts depending on which of the 10 possible Passlock sensors the vehicle is equipped with. The (BCM) then determines if the voltage received is a valid or invalid code. The scan tool will continue to display the Passlock voltage code (0.86-4.28 volts) received by the (BCM) when the ignition cylinder returns to the on/run position.

Tamper Timer : The scan tool displays the time remaining when in the tamper mode. The timer starts when the ignition switch is turned to the RUN position and the BCM receives a Passlock™ data voltage different from the last learned voltage. The timer has a delay of 10 minutes and will stay active even if the ignition switch is cycled from the RUN to the OFF position.

VCM/PCM in Fail Enable : The scan tool displays the state of the VCM/PCM fail enable mode. The scan tool displays YES when the Passlock™ system transitions from the Monitor Passlock™ Data state to the VCM/PCM Fail Enable state.

VTD Auto. Learn Timer : The scan tool displays Active/Inactive. The scan tool displays the current state of the Auto. Learn Timer, which must time out three times in order for the relearn procedure to be complete.

VTD Fuel Disable : The scan tool displays the state of the VTD fuel disable mode. The scan tool displays INACTIVE when the Passlock™ system verifies a valid password.

VTD Fuel Disable Until Ignition Off : The scan tool displays the state of the VTD fuel disable until Ignition off mode. The scan tool displays NO when the Passlock™ system verifies a valid password.

VTD Password : The scan tool displays OK/Incorrect. The scan tool displays OK when the PCM has received a learned fuel continue password from the VTD system. The scan tool displays Incorrect when the PCM has received a unlearned fuel continue password from the VTD system.
