WysokiOpen ABS pump motor circuit — hydraulic anti-lock brake system fault. The ABS control module detected an open or short circuit in the hydraulic pump electrical circuit.
OBD-II (EN): ABS Pump Motor Circuit Open
Code C0260 signals a fault in the ABS hydraulic pump motor circuit — the system detected an open or short circuit preventing proper anti-lock system operation. The cause may be a worn pump, damaged wiring, or a faulty relay. Due to driving safety, a quick diagnosis at a workshop with a professional ABS scanner is recommended.
Symptoms
Illuminated ABS or ESP/ESC warning light on the dashboard. Possible deactivation of ABS and traction control (TCS). Lack of typical ABS brake pedal pulsation during emergency braking. Standard braking system remains functional, but without anti-lock assistance.
Possible causes
• Faulty ABS module hydraulic pump electric motor (burned winding or mechanical lock) • Open or short circuit in wiring between EBCM module and ABS pump (corrosion, chafed harness) • Blown or faulty ABS pump relay • Faulty brake control module (EBCM/ABS ECU) — internal driver defect • Low supply voltage or poor ABS module ground connection causing false fault detection
