C1010
WysokiABS system / wheel speed sensor failure — damage to the circuit or signal of the left front wheel sensor (or ABS module relay, depending on the manufacturer).
OBD-II (EN): Left Front Wheel Speed Sensor Circuit Malfunction
Code C1010 signals an abnormality in the ABS system — most often related to the wheel speed sensor or the ABS module relay circuit. The anti-lock braking and traction control systems may be disabled, reducing driving safety, especially on wet or icy surfaces. Prompt diagnosis at a workshop equipped with a professional scanner that handles chassis codes is recommended.
Symptoms
ABS and/or ESP/TCS warning light is permanently on. Deactivation of the anti-lock braking system and traction control. Possible deactivation of the electronic stability control system (ESC). Extended stopping distance on slippery surfaces. Lack of Hill Start Assist function (if available). In some vehicles: warning message on the display.
Possible causes
• Damaged wheel speed sensor (short circuit, open circuit, or contamination). • Broken or damaged ABS sensor signal wire (connector corrosion, harness chafing). • Worn or damaged tone ring (phonic ring / tone ring) on the wheel hub. • Failure of the ABS pump/module relay or the ABS controller module itself. • Excessive play in the wheel bearing causing irregular sensor readings.
