THEFT DETERRENT SYSTEM FUEL ENABLE CIRCUIT
Vehicle operation is disabled if incorrect key or starting
procedure is used. Theft deterrent 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 40-60 Hz and is measured using DVOM in
Engine will not run
- PCM detects incorrect signal on Theft Deterrent System (TDS)
fuel enable circuit.
- Check for faulty connection at TDS module.
