Select “ABS” and “DATA MONITOR”, check “FR LH SENSOR”, “FR RH SENSOR”, “RR LH SENSOR”
and “RR RH SENSOR” with CONSULT.
NOTE:
Set the “DATA MONITOR” recording speed to “10 msec”.
6.
Read a value (wheel speed) of both normal wheel sensors and error-detecting wheel sensor.
Regarding the deference at 30 km/h (19 MPH) between the wheel speed detected by the error detecting
wheel sensor and the maximum/minimum wheel speed detected by the normal wheel sensors, is the differ-
ence within 5%, respectively?
YES
>> GO TO 18.
NO
>> GO TO 19.

>> Repair or replace error-detected parts.
2.
CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY CIRCUIT AND
GROUND CIRCUIT
1.
Check the voltage between ABS actuator and electric unit (control unit) harness connector and ground.
2.
Turn the ignition switch ON.
CAUTION:
Never start the engine.
3.
Check the voltage between ABS actuator and electric unit (control unit) harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair or replace error-detected parts.
3.
CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
1.
Turn the ignition switch OFF.
2.
Check the continuity between ABS actuator and electric unit (control unit) harness connector and ground.
