If one or more of the wheel speed is out of the range of the specified value, the DTC of the relevant wheel speed sensor is set.
PROBABLE CAUSES
- Malfunction of wheel speed sensor
- Damaged harness wires and connectors
- Malfunction of encoder for wheel speed detection
- Malfunction of ASC-ECU
- Malfunction of AWC-ECU
DIAGNOSIS
