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.
