VTD Fuel Disable

Scan Tool Displays ACTIVE or INACTIVE. The PCM enables the fuel injectors if the the proper Theft Deterrent Fuel Enable signal from the Vehicle Theft Deterrent (VTD) Control Module is received. The scan tool normally displays INACTIVE. If the VTD Control Module does not send the correct Theft Deterrent Fuel Enable Signal to the PCM, the display will switch to ACTIVE and the fuel system may be disabled. Refer to DTCs P1626, P1629, or the Vehicle Theft Deterrent System for further diagnosis.
