Circuit Description
WARNING: This page is about a different variant/trim than selected.
Vehicle operation is disabled if incorrect key or starting procedure is used. Vehicle Theft Deterrent (VTD) module enables crank circuit to starter and sends a signal to PCM if correct key is being used. If proper signal does not reach PCM fuel enable signal circuit, PCM will not pulse injectors on, disabling vehicle, even if crank circuit is by-passed. Signal should be between 40-60 Hz and is measured using DC scale on DVOM.
Conditions required to set DTC are:
- DTC P1626 is not set.
- An attempt is made to start engine.
- PCM detects incorrect signal on theft deterrent fuel enable circuit.
- Conditions present for longer than 2 seconds.
