Wireless Ignition Node (WIN)

B2205-ORIGINAL VIN MISSING/MISMATCH



Theory of Operation

When a valid Fob-Integrated-Key (FOBIK) is used and the ignition is rotated to the RUN position, the Wireless Ignition Node (WIN) "listens" to the CAN C bus for the broadcast of the Vehicle Identification Number (VIN) by the Powertrain Control Module (PCM).

- When Monitored:
The WIN monitors the VIN broadcast on the CAN C bus three times, when the ignition is turned to the RUN position. When the full VIN has been received by the WIN, all further broadcasts of the VIN are ignored for that ignition cycle.

- Set Condition:
When the VIN received from the CAN C bus does not match the VIN stored in the memory of the Wireless Ignition Node, the WIN will send the command to flash the Security warning lamp and set this DTC as active and the vehicle will immobilize. The DTC will remain active until a VIN matching the one stored in WIN memory is received by the module from the bus.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Wireless Ignition Node (WIN) Pre-Diagnostic Procedure

1. DETERMINE ACTIVE OR STORED DIAGNOSTIC TROUBLE CODE (DTC)

Is the DTC active or stored?

WIN - ACTIVE DTC

- Go To 2

WIN - STORED DTC

- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

2. CHECK THE VIN STORED IN THE PCM
1. Using the scan tool, compare the VIN that is stored in the PCM to the VIN of the vehicle's VIN plate.

Does the VIN stored in the PCM match the vehicle's VIN?

Yes

- Replace the Wireless Ignition Node. NOTE: Technicians must use the scan tool to perform the WIN Programming procedure after a module replacement.

- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.

No

- Replace and configure the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.
