B2205 - Original VIN Missing/Mismatch

For a complete wiring diagram, refer to.

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 WIN Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Pre-Diagnostic Procedure

Test Step 1 - DETERMINE ACTIVE OR STORED DIAGNOSTIC TROUBLE CODE (DTC)

Is the DTC active or stored?

WIN - ACTIVE DTC

• Go to Test Step 2

WIN - STORED DTC

• Perform the WIN Intermittent Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Intermittent Test

Test Step 2 - CHECK THE VIN STORED IN THE PCM

• 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 (WIN) in accordance with the Service Information. If this vehicle is equipped with a Steering Column Lock Module (BUX), it must also be replaced in accordance with the Service Information. When replacing the WIN and the Steering Column Lock Module, the Win MUST be programmed BEFORE the Steering Column Lock Module (ELV) is programmed.

• Replace and program the Wireless Ignition Node (WIN).

• Replace and program the Steering Column Lock Module (ELV).

• Perform the WIN Verification Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Verification Test

No

• Replace the Powertrain Control Module.

• Perform the Powertrain Verification Test. Refer to => Non-DTC Based Diagnostics. PCM Verification Test
