B2204-ECU CONFIGURATION MISMATCH

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

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.
