B2205-ORIGINAL VIN MISSING/MISMATCH

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


When a valid fobik is used and the ignition rotated to the RUN position, the WIN "listens" to the serial data bus for the broadcast of the Vehicle Identification Number (VIN) by the Powertrain Control Module (PCM). When the vehicle is assembled or if the WIN is replaced, the VIN of the vehicle the part has been installed in is hard coded to the module after 10 ignition cycles. This self test prevents modules from being swapped from vehicle to vehicle.


- When Monitored:
The WIN monitors the VIN broadcast on the serial data bus once, 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 serial data 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. 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.Initial Inspection and Diagnostic Overview


Diagnostic Test


1. DETERMINE ACTIVE OR STORED DTC
Is the DTC active or stored?

WIN - ACTIVE DTC


- Go To 2


WIN - STORED DTC


- Perform the THEFT AND SECURITY SYSTEMS VERIFICATION TEST.Theft and Security System Verification Test


2. CHECK THE VIN STORED IN THE PCM
With 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

NOTE: Technicians must use the scan tool to perform the WIN Programming procedure after a module replacement.
Replace the Wireless Ignition Node.
- Perform the THEFT AND SECURITY SYSTEMS VERIFICATION TEST.Theft and Security System Verification Test


No


- Replace and Configure the Powertrain Control Module.
- Perform the PCM Verification Test.Powertrain Verification Test
