Ignition Node Module - Operation

OPERATION

Following are brief descriptions of the systems that the Ignition Node Module (IGNM) controls.

08-0057-00610-31-IGNITION-SWITCH

IGNITION SWITCH

The Ignition Node Module (IGNM) incorporates an integral ignition switch that consists of four rotary positions with three detent positions and one spring-loaded position. The one extreme clockwise position is a spring-loaded momentary contact "START" position. When released from the "START" position, the switch will automatically return to the detent "RUN" position. The other position includes a detent "ACCESSORY" position and a detent "OFF" position.

SENTRY KEY IMMOBILIZER SYSTEM (SKIS)

All modules of the IGNM have transponder chips in all keys and FOBiK's. Upon failure of proper Sentry Key Immobilizer (SKIS) communication to the Powertrain Control Module, (PCM), the PCM will not allow the vehicle to crank. The engine will not re-crank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again. .

REMOTE KEYLESS ENTRY (RKE)

The midline model of the IGNM has the Remote Keyless Entry (RKE) feature. The FOBIK uses Radio Frequency (RF) signals to communicate with the Radio Frequency Hub (RF-Hub) and the RF-Hub relays the RKE requests to other modules in the vehicle over the CAN data bus. Power Locks - Operation

KEY REMOVAL INHIBIT SOLENOID

The Key Removal Inhibit Solenoid is internal to the IGNM. This prevents the key from going past accessory (to off) if the gear shifter is not in Park.
