Circuit Description

Vehicle Theft Deterrent (VTD) module produces a theft deterrent fuel enable signal when ignition is on and proper key resistor pellet is sensed by VTD module. Powertrain Control Module (PCM) monitors fuel enable signal during cranking.

Conditions for setting DTC:

• Engine running.
• PCM detects fuel enable signal is not present or incorrect.
• Conditions present longer than 2 seconds.
