For 1990-2009 cars only
Auto Learn Timer: The scan tool displays the seconds used by
the body control module (BCM) to learn valid code from the Passlock sensor. The learn
procedure consists of 3 consecutive periods.
Battery Voltage: The scan tool displays the battery system voltage.
Content Theft Lamp: The scan tool displays the state of the SECURITY lamp. The scan tool displays ON when activated by an unauthorized entry.
Content Theft State: The scan tool displays the state of the content theft feature. The scan tool displays ON when activated by an unauthorized entry.
Door Key Unlock: The scan tool displays the state of the drivers door lock cylinder. The scan tool displays ACTIVE when the cylinder is in the UNLOCK position.
Door Lock Switch: The scan tool displays the state of the power door lock switch. The scan tool displays ACTIVE when the switch is in the LOCK position.
Door Ajar Switch: The scan tool displays the position of the drivers door. The scan tool displays ACTIVE when the drivers door is ajar.
Ignition 1: 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 0: The scan tool displays the state of the ignition switch. The scan tool displays ACTIVE when the ignition switch is in the RUN position.
GM Part Number: The scan tool displays the part number assigned to the BCM that is currently in the vehicle.
Left Rear/Cargo Door Ajar Switch: The scan tool displays the position of the left rear door and the cargo door. The scan tool displays ACTIVE when the left rear or cargo door is ajar.
Passenger Door Ajar Switch: The scan tool displays the position of the passenger door. The scan tool displays ACTIVE when the passenger door is ajar.
Passlock Code: The scan tool displays the validity of the Passlock code received by the BCM. The scan tool displays OPEN, SHORTED, TAMPER and a valid code as a numeric value (1-10).
Passlock Data Voltage: The scan tool displays the voltage code from the Passlock sensor to the 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 Ignition Cycles: The scan tool displays the amount of times the ignition switch has been cycled.
Passlock Power: The scan tool displays the state of the Passlock 12-volt power supply from the BCM.
Passlock State: The scan tool displays the state of the Passlock system.
Right Rear Door Ajar Switch: The scan tool displays the position of the right rear door. The scan tool displays ACTIVE when the right rear door is ajar.
Seed and Key Timer: The scan tool displays 0-2550 seconds. The scan tool displays the current state of the Seed and Key Timer, which must time out in order for the relearn procedure to be complete.
PCM/VCM in VTD Fail Enable: The scan tool displays which state the powertrain control module (PCM) is currently in for the vehicle theft deterrent (VTD).
Security Calibration Number: The scan tool displays the security calibration part number in the BCM.
Security Lamp: The scan tool displays the state of the SECURITY lamp. The scan tool displays ON, OFF or FLASHING.
Security Suffix: The scan tool displays the security identification number in the BCM.
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.
VTD Auto Learn Timer: The scan tool displays which state the learn timer for the VTD is currently in.
VTD Fuel Disable: The scan tool displays the state of which the fuel delivery system is in.
VTD Fuel Disable Until Ign. OFF: The scan tool display the state of which the fuel delivery system is in according to the ignition switch position.
Battery Voltage: The scan tool displays the battery system voltage.
