5. Check sensor output voltage while shaking wiring harness by turn-

ing wheel 1/2 to 1 revolution per second (Voltage should be over
70mV when checked by multimeter and over 120mV/P-P when
checked by oscilloscope).

6. If there is no defect on above, replace sensor.

1. This code will appear if a wheel rotor teeth of four wheels is defective.

2. Check the teeth number of wheel rotor and condition.

1. If this code appear together with the items related with valve relay

failure, check the items related with valve failure first and repair de-
fective causes.

2. Check each valve using a over-riding function of tester on sole noid

valve diagnosis function.

3. Replace hydraulic modulator.
