What it means
A receiving module detected implausible data from comfort and convenience display B. Display state or input values fail plausibility checks and are rejected.
How it works
Comfort and convenience display B sends display and input information over the vehicle network to other modules. This code sets when a receiving module judges that information implausible and rejects it.
Common causes
Most likely first.
- Module internal fault or sensor input drift
- Software version mismatch after replacement
- Gateway module routing CAN messages incorrectly
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Scan all modules for codes and review freeze-frame data to identify which module reported the fault and when it occurred.
- Check whether display B and related comfort functions work, and note any warnings or functions that stopped responding.
- Inspect display B connectors and accessible wiring for looseness, damage, corrosion, or signs of water intrusion.
- Use a scan tool to compare display B status and input values with the vehicle's actual display state and user inputs.
- Check for related network or gateway faults and verify that CAN messages from display B are reaching the receiving module correctly.
- If the display or another module was recently replaced, verify software compatibility and configuration before condemning a module.
Common fixes
- Repair a loose, damaged, or corroded connector or wire at display B.
- Correct gateway routing or network configuration if diagnostics show messages are being misrouted.
- Update or configure a replacement module to the vehicle's required software version.
- Replace display B if its internal fault or drifting input is confirmed.
Can I keep driving?
This code does not by itself indicate an engine or emissions problem, but comfort functions that rely on display B data may be unavailable. Drive attentively if any related controls or warnings are affected, and avoid relying on a disabled feature.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
