Wheel Speed Sensor senses vehicle speed and difference between front and rear wheel speed. Opreation for getting Rotating Speeds of front/rear wheel can be got from deviding wheel speed sensor Rotating Speeds of front/rear by 2. A 4WD ECU receives this signal from wheel speed sensor directly.
This code related to Wheel Speed Sensor is set when difference between front and rear wheel speed is above 30km/h for more than 30sec or loss of signal is occurred. If failure is detected TCCU prohibits the ITM control.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Loss of signal | ● Wheel speed sensor,TCCU connector looseness and poor terminal to wire connection. ● wheel speed circuit open or short to battery. ● wheel speed sensor airgap. ● Faulty wheel speed . ● Faulty TCCU . |
Enable Conditions | ● Fault cleared ignition cycle | |
Threshold Value | ● Speed defference 30kph | |
Diagnostic Time | ● 30 sec | |
MIL on condition | ● 0.5 Sec. | |
Fail Safe |
