Causes
- Incorrect or incomplete module coding/variant settings
- Corrupted or interrupted software/calibration reflash
- Installed module with incompatible software or part number
- Low battery voltage or power interruption during programming
- Faulty module memory (EEPROM/Flash) or internal failure
- CAN/LIN network communication errors or bus wiring/connectors faults
Symptoms
- Warning messages or lamp illumination related to affected systems
- Certain vehicle features disabled or defaulted to reduced functionality
- Related control module(s) not responding or reporting errors
- Multiple U-codes or other communication DTCs present
- Vehicle may enter limp or reduced-function mode for affected systems
What to check
- Read all stored DTCs and freeze frame data from all modules (use factory-capable diagnostic tool)
- Check battery voltage and charge state (should be within manufacturer specs before programming)
- Query module part number, software/calibration ID and coding/variant values
- Check for recent repair, module replacement, or software update history
- Inspect CAN/LIN bus wiring, connectors and grounds for damage, corrosion or loose connections
- Look for other network-related DTCs (U0401, U0100, U1000, etc.) that indicate broader communication faults
Signal parameters
- Module source address (CAN ID)
- Message ID and message frequency for configuration frames
- Data length and payload bytes of the configuration message
- Coding/Calibration ID (CAL ID) or software part number (S/W ver)
- Checksum or CRC value where applicable
- Timestamp of when configuration was received
Diagnostic algorithm
- Record the exact U2202 event: timestamp, freeze frame and any concurrent DTCs from all modules
- Confirm battery voltage and charge—restore proper battery condition before further testing or programming
- Use Land Rover factory diagnostic tool (SDD/Pathfinder/JLR approved tool) to read module(s) full info: part numbers, software/coding IDs and any stored configuration logs
- Compare the module software/coding to vehicle build data (VO) and to other identical modules on the vehicle if applicable
- Check physical layer: inspect CAN/LIN connectors, wiring, grounds and gateway connections for damage, corrosion or poor contact
- If message corruption suspected, check for noise or bus errors with an oscilloscope or CAN diagnostic tool
- If a recent reflash/programming failed or was interrupted, reattempt programming with correct, manufacturer-approved files and procedures; follow battery/ignition requirements
- If the module reports incompatible part number or corrupted memory, reflash or replace the module per manufacturer instructions and re-code to vehicle order
- After repair or reprogramming, clear DTCs, perform required adaptations or config procedures, then cycle ignition and test drive to confirm issue does not return
- If recurring after correct programming and good network health, consider replacing the affected module and retest
Likely causes
- Incorrect module coding after repair or replacement
- Interrupted or failed software update/flash
- Installed module with incompatible part number or calibration
- Network communication error (CAN bus) during transfer
Fault status
Status
Invalid configuration data received by a control module — configuration, coding or calibration data is missing, corrupted, or incompatible; module may require reprogramming or replacement.
Repair difficulty: Medium
Diagnostic time: 1.0-3.0 hours
