What Does the B2204 Jeep Code Mean?

The Radio Frequency Hub (RF-Hub) must be configured for various parameters such as model year and vehicle line, after a service replacement. The RF-Hub 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. The RF-Hub checks the feature configuration at power up during the initialization process, and continuously through the ignition cycle.
This Diagnostic Trouble Code (DTC) sets when the RF-Hub detects a mismatch of Model Year, vehicle line, body style or market country between the current vehicle configuration of the module and the information sent out on the CAN bus. Once set, this DTC is latched for the entire ignition cycle.
