C0265: EBCM Relay Circuit
Standardized SAE J2012 code · C02xx codes
Safety-critical system. Faults in airbags, brakes, steering or high-voltage components can put people at risk. Follow the manufacturer's service information and safety procedures, or have the vehicle checked by a qualified workshop.
What does C0265 mean?
The Electronic Brake Control Module has detected a fault in its main supply relay circuit. Without proper relay supply the EBCM cannot operate the hydraulic unit and ABS as well as stability control are disabled.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
Common causes
- High EBCM relay failed
- Medium Internal EBCM fault (relay integrated)
- Low Power supply wiring or fuse fault
