OBD-II (EN): ABS Solenoid Relay Circuit Fault
Code C0270 indicates a fault in the ABS solenoid valve relay circuit, causing the wheel anti-lock braking system to deactivate. The most common causes are: a damaged relay, a blown fuse, or a wiring problem. Due to driving safety, diagnosis at an authorized service center or an automotive electrician is recommended as soon as possible.
Symptoms
• ABS warning light is on the dashboard • ABS system is disabled – no anti-lock braking assistance • Possible illumination of the ESP/DSC/TCS warning light (stability systems linked to ABS) • Brake pedal may behave differently during hard braking • In some vehicles, possible deactivation of the entire brake assist system (EBD)
Possible causes
• Faulty ABS solenoid valve relay (wear, burned coil or contacts) • Open or short circuit in the wiring harness between the ABS module and the relay • Corrosion or oxidized electrical connectors in the relay circuit • Faulty ABS control module (EBCM/EBCM) – less common • Blown fuse in the ABS relay circuit
