2000 Chevrolet S10/T10 P/U 2WD V6-4.3L VIN WSECTION Scan Tool Data Definitions
Auto Learn Timer: The scan tool displays the seconds used by the BCM to learn valid code from the PASSLOCK(TM) 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 Handle Switch: The scan tool displays the position of the door handle. The scan tool displays ACTIVE when a door handle is raised and INACTIVE with all doors closed and the door handles at rest.
Door Key Switch: The scan tool displays the state of the door key switch. The scan tool displays ACTIVE when the switch is activated in either door key cylinder.
Drivers Door Jamb Switch: The scan tool displays the position of the drivers door. The scan tool displays ACTIVE when the drivers door is open.
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 3: The scan tool displays the state of the ignition switch. The scan tool displays ACTIVE when the ignition switch is in the RUN position.
Manufacture Enable Counter (MEC): The scan tool displays the actual value for the MEC in the BCM. This information is for the assembly plant only.
Module Part Number: The scan tool displays the part number assigned to the BCM that is currently in the vehicle.
Passlock(TM) Code: The scan tool displays the validity of the PASSLOCK(TM) code received by the BCM. The scan tool displays OPEN, SHORTED. TAMPER and a valid code as a numeric value (1-10).
Passlock(TM) Data Voltage: The scan tool displays the voltage code from the PASSLOCK(TM) sensor to the BCM. The BCM determines if the voltage received is a valid or invalid code voltage.
Passlock(TM) State: The scan tool displays the state of the PASSLOCK(TM) system.
Security Calibration Number: The scan tool displays the security calibration part number in the BCM.
Security Lamp State: 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(TM) 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 Fail Enable: The scan tool displays the state of the VCM/PCM fail enable mode. The scan tool displays YES when the PASSLOCK(TM) system transitions from the Monitor PASSLOCK(TM) Data state to the VCM/PCM Fail Enable state.
VCM/PCM Fuel Continue: The scan tool displays the state of the VCM/PCM fuel continue mode. The scan tool displays YES when the PASSLOCK(TM) system verifies a valid password to the BCM.
VCM/PCM Learn Timer: The scan tool displays the state of the VCM/PCM 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(TM) 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(TM) system verifies a valid password.
VTD Password Learn Mode: The scan tool displays the state of the VTD password learn mode. The scan tool displays INACTIVE when the PASSLOCK(TM) system is not in a learn mode.
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 Handle Switch: The scan tool displays the position of the door handle. The scan tool displays ACTIVE when a door handle is raised and INACTIVE with all doors closed and the door handles at rest.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
