2. Monitor wheel speed sensor
3. Trial run the car until the setup speed upper
limit is reached; then gradually slow down the
car to zero speed. Repeat the steps several times.
Is C0028 reset or does the rear right wheel speed
variation exceed 5km/h (3 mile/h) during driving
if compared with the speed of any other wheel?

1. The car speed sensor is still detached from the
straddling wire harness.
2. Connect the ohmmeter to the rear right wheel
speed sensor terminals A and B.
3. Select AC mV scale.
4. Rotate the rear right wheel while observing
the voltmeter.
Is the AC voltage within the range required?
