CHECK WHEEL SENSOR HARNESS

1.

Turn the ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) harness connector.

3.

Disconnect wheel sensor harness connector.

4.

Check the continuity between ABS actuator and electric unit (control unit) harness connector and wheel
sensor harness connector. (Check the continuity when steering wheel is steered to RH and LH, or center
harness in wheel housing is moved.) 

Measurement connector and terminal for power supply circuit

Measurement connector and terminal for signal circuit

5.

Check the continuity between ABS actuator and electric unit (control unit) harness connector and the
ground.

Is the inspection result normal?

YES

>> GO TO 15.

NO

>> Repair or replace error-detected parts and GO TO 15.

15.

CHECK DATA MONITOR (4)

1.

Connect ABS actuator and electric unit (control unit) harness connector.

2.

Connect wheel sensor harness connector.

3.

Erase self-diagnosis result for “ABS” with CONSULT.

4.

5.

Start the engine.

6.

Select “ABS” and “DATA MONITOR”, check the “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”.

7.

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
