DTC

C1413

Front Speed Sensor RH Circuit Output

DTC

C1414

Front Speed Sensor LH Circuit Output

DESCRIPTION

Each speed sensor detects the wheel speed and sends the signals to the skid control ECU (brake booster with master cylinder assembly). These signals are used for ABS control.

HINT:

The output voltage values shown below are for when the vehicle wire harnesses are connected to the skid control ECU (brake booster with master cylinder assembly) and the speed sensors.

DTC No.

MONITOR DESCRIPTION

The skid control ECU (brake booster with master cylinder assembly) monitors the output value of the speed sensors. When the vehicle is being driven and a sudden irregular change in acceleration due to iron particles being attached to the speed sensor is detected repeatedly, or periodic sudden changes in acceleration due to iron particles being attached to the speed sensor rotor is detected, the skid control ECU (brake booster with master cylinder assembly) judges that speed sensor noise is occurring and illuminates the MIL and stores a DTC.

Also, when the vehicle is being driven and the output value of the speed sensor is momentarily interrupted repeatedly, the skid control ECU (brake booster with master cylinder assembly) judges that there is a momentary interruption in the speed sensor circuit and illuminates the MIL and stores a DTC.
