1. Test-drive the vehicle between 1 km/h (1 mph) and
15 km/h (9 mph).
NOTE: Drive the vehicle on the road, not on a lift.
2. Check the RF, LF, RR, LR WHEEL SPEED in the ABS DATA LIST with the HDS.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the wheel
speed sensor 2P connector and the ABS modulator-
control unit 25P connector. Refer to intermittent
failures troubleshooting (see page 19-50).
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Check that the appropriate wheel speed sensor is properly mounted (see page 19-92).

(see page 19-90).
Intermittent failure, the system is OK at this
time. The DTCs may be indicated under these conditions:
 The vehicle goes into a spin.
 The ABS continues to operate for a long time.
 Snow, dirt, or debris build-up on the wheel speed sensor or magnetic encoder.
 Misadjusted brake pedal position switch.
 Contaminated brake fluid.
1. Raise the vehicle, and support it with safety stands in the proper locations (see page 1-11).
2. Turn the appropriate wheel by hand.

NOTE: Drive the vehicle on the road, not on a lift.
7. Check for DTCs with the HDS.
Check for loose terminals between the wheel
speed sensor 2P connector and the ABS modulator-
control unit 25P connector. If necessary, substitute
a known-good ABS modulator-control unit
(see page 19-90), and retest.
If any other DTCs are indicated, go to the
indicated DTCs troubleshooting. If DTCs are not
indicated, intermittent failure, the system is OK at
the time. 1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to
ON (II) again.
4. Wait 5 seconds.

1. Turn the ignition switch to LOCK (0).
2. Release the connector clamp (A), then disconnect the wheel speed sensor connector (B).
3. Remove the clips, the bolt, and the wheel speed sensor (C).
4. Install the wheel speed sensor in the reverse order of removal, and note these items:  Install the sensor carefully to avoid twisting the wires.
 If the wheel speed sensor comes in contact with the wheel bearing, it is faulty. Investigate the cause beforereplacing the sensor.
5. Start the engine, and make sure the ABS indicator goes off.
6. Test-drive the vehicle, and make sure the ABS indicator does not come on.

4. Apply multi-purpose grease to the wheel speedsensor O-ring (A) and the sensor hole in the knuckle
(B).
5. Insert the guide pin tool (A) into the wheel speed sensor bolt hole until the shoulder of the tool
contacts the wheel speed sensor bracket.
NOTE: To prevent O-ring damage, the wheel speed
sensor must be installed with the guide pin tool. 6. Insert the wheel speed sensor (A) and the guide pin
tool (B) into the bolt hole on the knuckle.
NOTE: To ensure proper alignment when pushing
the wheel speed sensor into the knuckle housing,
do not hold the sensor bracket during installation,
hold the sensor wire.
7. Gently push and pull the wheel speed sensor in and out to make sure the O-ring is sliding properly in its
housing. While you are doing this, make sure the
sensor doesn’t come out of the knuckle assembly. If
the sliding effort is too high, remove the wheel
speed sensor, inspect the O-ring for damage, and
start the installation process again.
8. Remove the guide pin tool, then install the bolt, and tighten it to specified torque.
9. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the front
wheel.
10. Start the engine, and make sure the ABS indicators go off.
11. Test-drive the vehicle, and make sure the ABS indicators do not come on.
