VTD Fuel Disable

The scan tool displays ACTIVE or INACTIVE. The Theft Deterrent Fuel Enable circuit is an input from the vehicle theft deterrent system 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 system does not sent the correct theft deterrent fuel enable signal to the PCM, the display will switch to ACTIVE and the fuel system may be disabled.
