Lumina V6-3.1L VIN J (2000)
Antitheft Relay: Description and Operation
The theft deterrent module enables the theft deterrent relay by grounding the start enable circuit. When the theft deterrent relay is ON, it completes the
circuit between the ignition switch and the starter. This allows the engine to crank when the ignition switch is in the RUN position. The transaxle must be
in either PARK or NEUTRAL in order for this to happen.
When the theft deterrent relay is disabled, the circuit between the ignition switch and the starter is opened. This prevents the engine from cranking when
the ignition switch is in the RUN position.
