WysokiABS brake system error – solenoid valve or ABS control module circuit fault. The code signals incorrect operation of hydraulic or electrical components of the anti-lock braking system.
OBD-II (EN): ABS Hydraulic Control Unit Circuit Fault
Code C0375 indicates a fault in the ABS system – most often related to the hydraulic unit solenoid valve or the EBCM control module. Causes can include a short circuit in the wiring harness, connector corrosion, or a faulty actuator component. Due to the direct impact on braking effectiveness, diagnosis at a workshop with a bi-directional control scanner is recommended as soon as possible.
Symptoms
ABS or ESP/ESC warning light on the dashboard. Deactivation of the anti-lock braking system (ABS) and traction control (TCS). Possible increased braking distance on slippery surfaces. No emergency braking assistance. In some vehicles, additional fault codes related to stability control may appear.
Possible causes
• Faulty solenoid valve in the ABS hydraulic pump (HCU – Hydraulic Control Unit) • Short or open circuit in the solenoid valve control electrical circuit • Faulty ABS/EBCM control module (Electronic Brake Control Module) • Contamination or corrosion of the ABS module connector • Damaged wires or wiring harness leading to the hydraulic unit

Does code C0375 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.
