C0265
WysokiEBCM (Electronic Brake Control Module) motor relay circuit damage. The code indicates a fault in the relay powering the ABS system pump motor.
OBD-II (EN): EBCM Engine Relay Circuit Malfunction
Code C0265 signals a fault in the EBCM module motor relay circuit, responsible for operating the ABS hydraulic pump. The cause could be a damaged relay, blown fuse, connector corrosion, or a fault in the ABS controller itself. Due to the direct impact on braking effectiveness, we recommend immediate diagnosis at a service center with a professional scanner.
Symptoms
ABS warning light on the dashboard. ESP/VSC or traction control warning light on. Deactivation of the ABS and stability control systems. Possible increased braking distance on slippery surfaces. In some vehicles, activation of the Check Engine light. No operation of the ABS hydraulic pump during simulated wheel slip.
Possible causes
• Faulty EBCM motor relay or blown ABS module fuse • Short or open circuit in the power/ground circuit of the EBCM module • Corroded or loose connectors on the ABS module • Faulty EBCM module (electronic brake control unit) • Faulty ABS hydraulic pump causing relay overload
Affected systems
Does code C0265 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.
