For 1990-2009 cars only
Auto Learn Timer: The scan tool displays the seconds used by
the BCM to learn valid code from the Passlock™ sensor. The learn procedure consists
of 3 consecutive periods.
Battery 1: The scan tool displays the battery system voltage.
Drivers Door Switch: The scan tool displays the position of the drivers door switch. The scan tool displays ACTIVE when the drivers door is open and INACTIVE when the drivers door is closed.
Horn Relay Command: The scan tool displays the horn relay command input. The scan tool displays ACTIVE when the horn relay is commadded on.
Horn Relay Feedback: The scann tool displays the status of the horn relay feedback circuit. The scann tool displays ACTIVE when a feedback signal is present during a horn relay on condition.
Ignition 1 Input: The scan tool displays the state of the ignition switch. The scan tool displays ACTIVE when the ignition switch is in the RUN or CRANK position.
Ignition 2 Input: The scan tool displays the state of the ignition switch. The scan tool displays ACTIVE when the ignition switch is in the RUN position.
Key Learned: The scan tool displays the number of learned keys.
Key Learn Enable: The scan too displays the key learn enable status. The scan tool displays ACTIVE during key learn.
Passlock Input: 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.
Passlock Power Feedback: The scan tool displays the state of the Passlock™ system.
Passlock 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.
Security LED: The scan tool displays the state of the SECURITY lamp. The scan tool displays ON, OFF or FLASHING.
VTD Auto Learn Timer: The scan tool displays the state of the VTD learn timer. The scan tool displays INACTIVE when the BCM is not in a learn mode.
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: 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 Learn Enable: The scan tool displays the state of the VTD password learn mode. The scan tool displays NO when the Passlock™ system is not in a learn mode.
Battery 1: The scan tool displays the battery system voltage.
Drivers Door Switch: The scan tool displays the position of the drivers door switch. The scan tool displays ACTIVE when the drivers door is open and INACTIVE when the drivers door is closed.
