What it means
A receiving module detected implausible data from comfort and convenience display A. Display state or input values fail plausibility checks and are rejected.
How it works
Comfort and convenience display A provides display-state or user-input information to other vehicle modules, such as information used by cabin convenience features. This code sets when a receiving module considers those reported values implausible and rejects them; the affected functions depend on which information they use.
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 the display and receiving modules for communication or display-related codes, and note which comfort or convenience functions are affected.
- Review available live display state and input data to see whether values from display A are missing, stuck, or inconsistent.
- Inspect display A's connector, power, ground, and CAN wiring for loose pins, corrosion, damage, or signs of a recent dash repair.
- Check whether other modules show network faults that could interrupt or misroute display messages.
- Verify compatible software and configuration for display A, the receiving module, and gateway, especially after a display or module replacement.
- If wiring and configuration are sound, use manufacturer-approved network diagnostics to isolate display A, the receiving module, or gateway.
Common fixes
- Reconnect or repair damaged display A wiring, power, ground, or CAN connections.
- Correct related network faults in the gateway or receiving module.
- Install compatible software or configuration after display or module replacement.
- Replace display A or a confirmed faulty receiving or gateway module.
Can I keep driving?
This fault usually affects display-related or convenience functions rather than basic engine operation, so driving may be possible if there are no safety warnings. Do not drive if the display loss hides critical warnings or if any brake, steering, or restraint warning also appears.
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.
