Wireless Ignition Node Receiver - Operation

OPERATION

Following are brief descriptions of the systems that the WIN controls.

IGNITION SWITCH

The Wireless Ignition Node (WIN) 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 "ON" position. The other position includes a detent "ACCESSORY" position and a detent "LOCK" position.

The WIN reads the position of the ignition switch and transmits the data via the CAN data bus. These positions include "LOCK" with ignition key-out, "LOCK" with ignition key-in, "ACCESSORY,""RUN," and "START."

SENTRY KEY IMMOBILIZER SYSTEM (SKIS)

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. Sentry Key Immobilizer System - Operation

REMOTE KEYLESS ENTRY (RKE)

The Remote Keyless Entry (RKE), transmitter uses Radio Frequency (RF) signals to communicate with the WIN, and the WIN relays the RKE requests to other modules in the vehicle over the CAN data bus. Power Locks - Operation

TIRE PRESSURE MONITORING (TPM)

The Tire Pressure Monitoring (TPM) system uses radio and sensor technology to monitor tire air pressure levels. Description and Operation.

REMOTE START WITH/EXTENDED RANGE ANTENNA

Further information concerning the Remote Start System can be located in Starting System. Description and Operation

BRAKE TRANSMISSION SHIFTER INTERLOCK (BTSI)

The Brake Transmission Shifter/Ignition Interlock (BTSI) is controlled by the WIN. The BTSI prevents the transmission gear shifter from being moved out of PARK without a driver in place. For more information view the Brake Transmission Shift Interlock Mechanism for the related transmission.

PARK SHIFT INTERLOCK

The key removal inhibit solenoid internal to the WIN prevents the FOB with Integrated KEY (FOBIK) from being rotated in the ignition switch to the LOCK position for all vehicles with an automatic transmission unless the transmission shift lever is in the PARK position. The WIN module monitors a hard wired input from a switch integral to the automatic transmission shifter module to control this feature. The key removal inhibit solenoid is electronically disabled internally by the WIN on vehicles with a manual transmission.
