When the tone wheel rotates, adjacent to the sensor pole component, an alternating current signal is generated in the coil with a frequency proportional to the wheel speed.
Wheel Speed Sensor generates a signal which is sent to TCCU.
This failure code is related to the Wheel Speed Sensor and is set if no signal is received by TCCU.
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 |
