VTD Fuel Disable

The scan tool displays Active/Inactive. The PCM receives a 40-60 Hertz signal from the Body Control Module (BCM) when the proper starting procedure occurs. When the PCM receives this 40-60 Hertz signal the fuel system is enabled and the engine starts. The scan tool displays Active once the hertz signal is received by the PCM. If an improper starting procedure occurs, the BCM will not send the 40-60 Hertz signal to the PCM and the PCM disables the fuel system. The scan tool displays Inactive.
