Vehicle Stability Control System

DTC C1236/36 Foreign Object is Attached on Tip of Front Speed Sensor LH

DESCRIPTION

DTC Detecting Condition:

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system. The speed sensor detects changes in the magnetic field generated by the magnetic rotor which has the north and south poles evenly located in circumferential direction and generates the vehicle speed pulse. The skid control ECU detects each wheel speed based on the vehicle speed pulse.

DTCs C1275/75 to C1278/78 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1275/75 to C1278/78 are output only in the test mode.

HINT:
- DTC C1235/35 is for the right front speed sensor.
- DTC C1236/36 is for the left front speed sensor.
- DTC C1238/38 is for the right rear speed sensor.
- DTC C1239/39 is for the left rear speed sensor.
