RAM 2500 Truck 2WD L6-6.7L DSL Turbo (2010)
Ignition Switch: Description and Operation
Wireless Ignition Node Receiver - Description
DESCRIPTION
This vehicle is equipped with a Wireless Ignition Node (WIN). 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 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, which are secured to the instrument panel
structure with screws. Two connector receptacles are integral to the back of the switch housing. One connects the WIN to the vehicle electrical system
through a dedicated takeout and connector of the instrument panel wire harness. The other 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. The WIN 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. 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).
