B2204-ECU CONFIGURATION MISMATCH



Theory of Operation

The Wireless Ignition Node (WIN) must be configured for various parameters such as model year and vehicle line, after a service replacement. The WIN checks for the proper configuration by comparing the values stored to those sent out on the serial data bus. The repair of this fault does not involve any external circuitry and centers on verifying the module is configured correctly.

- When Monitored:
The WIN checks the feature configuration at power up during the initialization process, and continuously through the ignition cycle.

- Set Condition:
This DTC sets when the WIN detects a mismatch between the current configuration of the module and information sent out on the serial data bus. Once set, this DTC is latched for the entire ignition cycle.





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

1. DETERMINE ACTIVE OR STORED 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. RESET/RECONFIGURE THE TOTALLY INTEGRATED POWER MODULE (TIPM)
1. Turn the ignition on.
2. Using the scan tool, select ECU View. This will list the modules on the vehicle. Read and record the listed modules.

3. Using the scan tool, select the the Totally Integrated Power Module (TIPM) and then press Miscellaneous Functions.
4. Press Reset ECU.
5. Cycle the ignition from on to off three times and read the active WIN DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 3

No

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

3. RESET/RECONFIGURE THE WIN
1. Using the scan tool, select the the WIN and then press Miscellaneous Functions.
2. Press Reset ECU.
3. Cycle the ignition from on to off three times and read the active WIN DTCs.

Does the scan tool display this DTC as active?

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
