WysokiConfiguration Incompatibility – CAN bus recovery after 'bus off' state. The vehicle communication network node has disconnected from the bus due to an excessive number of transmission errors.
OBD-II (EN): CAN Bus Configuration Inconsistency - Bus Off Recovery
Code U0375 means that one of the vehicle's electronic modules has disconnected from the CAN bus due to configuration incompatibility or an excessive number of communication errors. This can lead to improper operation of many systems simultaneously – from ABS to the transmission. We recommend prompt diagnostics at a professional workshop, as self-repair requires specialized equipment for CAN network analysis.
Symptoms
MIL (Check Engine) light or warning lights for systems supported by the CAN network illuminated. Random or persistent errors from other modules (ABS, ESP, transmission, HVAC). No communication with one or more controllers during diagnostic scanning. Possible engine power limitation (limp mode). Non-functional electrical equipment controlled by the network (e.g., power seats, cruise control, door module).
Possible causes
• Damage or corrosion of the CAN bus wiring harness (short circuit, open circuit, excessive resistance) • Faulty controller (ECU/TCU/BCM or other network module) generating excessive errors and disconnecting from the bus • Software or configuration version incompatibility between modules (e.g., after controller replacement without programming) • Poor ground or power potential of the module – leads to unstable communication • Electromagnetic interference (EMI) caused by a faulty alternator, glow plugs, or other sources • Damaged or missing CAN bus terminating resistor (120 Ω)

Does code U0375 require professional diagnostics?
The code alone is not enough. To find the cause, you need to read live data, check freeze frame conditions, and compare with vehicle behavior. Book a diagnostic session.
