VTD Fuel Disable

Scan Tool Displays ACTIVE or INACTIVE. (if applicable) The Theft Deterrent Fuel Enable circuit is an input from the Vehicle Theft Deterrent Control Module that signals the PCM to enable the injectors if the proper signal is received. The scan tool will normally display INACTIVE. If the Vehicle Theft Deterrent 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 Vehicle Theft Deterrent (VTD) Description in Theft Deterrent for further information.
