Co oznacza ten kod błędu?

The right front wheel speed sensor is sending a signal, but its value does not match the other wheels. The ABS control module sees the wheel apparently stopping, turning too slowly or changing speed in an unnatural way. Because the circuit itself is intact, the cause is more often mechanical around the sensor, such as the brakes or the bearing. The equivalent code for the left front wheel is ABS-0011.

Możliwe przyczyny

The wheel has locked or stuck, for example from a sticking brake caliper
Loose wheel speed sensor or dirt between the sensor and its mounting
Damaged or dirty tone ring that the sensor reads
Play in the wheel bearing or vibrations from the driveshaft
Faulty wheel speed sensor or a faulty outlet valve in the ABS unit

Co możesz zrobić

1Check that the brake caliper on the right front wheel is not sticking and the wheel spins freely
2Check the wheel bearing for play and noise
3Remove the wheel and check that the sensor sits flush against its mounting with no dirt or rust underneath
4Check that the tone ring is secure, complete, clean and undamaged
5Clear the code and road test; if it remains, have the sensor and ABS unit checked by a workshop
6ABS is safety-critical – avoid hard braking until the fault is fixed and do not let anyone unqualified work on the brake system
