Dodge Journey: Description, Operation

DESCRIPTION

This vehicle is equipped with a Wireless Ignition Node (WIN) (1). The WIN and the FOB with Integrated Key (FOBIK) are the primary components of the keyless ignition system. The only visible component of the WIN is the ignition switch (5) located on the face of the instrument panel just to the inboard side of the steering column.

The WIN housing is constructed of molded black plastic and it includes four integral mounting bosses (4), which are secured to the instrument panel structure with screws. Two connector receptacles are integral to the back of the switch housing. One (3) connects the WIN to the vehicle electrical system through a dedicated takeout and connector of the instrument panel wire harness. The other (2) is a dedicated connector for the coaxial cable input from the optional remote start system external antenna module.

The WIN is an integrated electronic receiver that replaces the ignition switch. It communicates with other electronic modules in the vehicle over the Controller Area Network (CAN) data bus.

The WIN interfaces with the Remote Keyless Entry (RKE) FOBIK and the Tire Pressure Monitor (TPM) sensors (if equipped) using Radio Frequency (RF) communication, with the Sentry Key Immobilizer System (SKIS) transponder within the FOBIK using Low Frequency (LF) communication. It also communicates with the TPM trigger transponders (if equipped) and steering column lock module (if equipped) using a Local Interface Network (LIN) data bus connection.

The WIN provides a switched 12-volt source through an isolated switch for the steering column lock module required for certain export market vehicles. It also contains a key removal inhibit solenoid, an electronic Brake Transmission Shift Interlock (BTSI) solenoid, a key-in warning contact and it serves as the real time vehicle clock by transmitting the clock information to other electronic modules over the CAN data bus.

The WIN cannot be adjusted or repaired, but is flash update capable. If ineffective or damaged, the entire WIN must be replaced. When replacing the WIN, you must also replace the steering column lock module (if equipped).

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.

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.

TIRE PRESSURE MONITORING (TPM)

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

REMOTE START WITH/EXTENDED RANGE ANTENNA

Further information concerning the Remote Start System can be located in , Starting System.

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.

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.
