A receiving module detected implausible data from the inductive (wireless) HV battery charging module. Coil power, alignment or temperature values fail plausibility checks and are rejected, halting the wireless charge session.
High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.
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
Most likely causes
- Module internal fault or sensor input drift
- Software version mismatch after replacement
- Gateway module routing CAN messages incorrectly
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: hard
What each character of U044C means
- U: Communication network
- 0: Generic code: same on every make
- 4: Subsystem depends on the code range
- 4C: Specific fault in that system
