DTC C1466 RR wheel speed sensor signal

DTC C1467 RL wheel speed sensor signal

Description of functions


The speed sensor detects the wheel speed and sends the signal to the skid control computer. These signals are used for ABS control.
The speed sensor detects magnetic field changes in the magnetic rotor, where the N and S poles are evenly allocated in a circumferential direction, and generates a vehicle speed pulse.
With this vehicle speed pulse, the skid control computer detects each wheel's speed.

NOTE:
The following voltage outputs are the values when the vehicle harness connectors are connected to the skid control computer (brake actuator ASSY) and the speed sensor.

CAUTION:
When the skid control computer (brake actuator ASSY) has been replaced, make sure to perform VSC centering.
