A receiving module detected implausible data from the high-voltage battery pack sensor module. Cell-voltage and temperature values fail plausibility checks and are rejected; SoC and SoH calculations switch to a default model.
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
- It can trigger limp mode.
What each character of U059B means
- U: Communication network
- 0: Generic code: same on every make
- 5: Subsystem depends on the code range
- 9B: Specific fault in that system
Frequently asked questions
