C0105
WysokiError in the Rear ABS Solenoid Valve/Motor Circuit (Both Wheels) – Circuit No. 2 Fault. The code indicates incorrect operation of the rear anti-lock braking system actuators.
OBD-II (EN): Rear ABS Solenoid/Motor Circuit Malfunction (Both Wheels) - Circuit 2 Fault
Code C0105 signals a fault in the solenoid valve or hydraulic motor circuit of the rear ABS system – a system crucial for braking safety. This may be caused by damaged wiring, connector corrosion, or failure of the ABS module itself. Due to the direct impact on braking effectiveness, prompt diagnosis at an authorized service center or workshop equipped with a professional ABS scanner is recommended.
Symptoms
ABS or ESP/ESC warning light illuminated on the dashboard; possible CHECK ENGINE light illumination; ABS system disabled or operating incorrectly (lack of braking modulation in emergency situations); in some cases, noticeable brake pedal pulsation or incorrect behavior during hard braking; possible warning messages about the vehicle stability control system.
Possible causes
• Damaged ABS solenoid valve or hydraulic module (HCU) pump motor for the rear ABS circuit • Open or short circuit in the power/control wiring harness for the ABS solenoid valve • Corrosion or oxidation of the ABS module electrical connectors • Damaged ABS control module (EBCM/ABS ECU) • Interference or fault on the CAN bus connecting the ABS module to other vehicle controllers

Does code C0105 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.
