Check for loose terminals in the VSA
modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.
Reinstall the wheel speed sensor, and check
the mounting position (see page 19- 173).1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle. Drive the vehicle at 20 km/h
(13 mph) or more, and go a distance of 100 m
(328 ft) or more.
NOTE: Drive the vehicle on the road, not on a lift.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the wheel
speed sensor 2P connector and the VSA modulator-
control unit 37P connector. Refer to intermittent
failures troubleshooting (see page 19-98).
5. Turn the ignition switch to LOCK (0).
6. Disconnect the VSA modulator-control unit 37P connector (see step 2 on page 19-171).

NOTE: While doing this troubleshooting, avoid
vibrations or shaking the vehicle.
1. Park the vehicle on a flat and level surface.
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
5. Wait 60 seconds or more.
6. Check for DTCs with the HDS.

2. Clear the DTC with the HDS.
3. Test-drive the vehicle at 10 km/h (7 mph) or more.
NOTE: Drive the vehicle on the road, not on a lift.
4. Check for DTCs with the HDS.
Go to step 5.
If any other DTCs are indicated, go to the
indicated DTCs troubleshooting. If DTCs are not
indicated, there was an intermittent failure, the
system is OK at this time.
5. Test-drive the vehicle. Check the LATERAL ACCELERATION SENSOR in the VSA DATA LIST
with the HDS while driving in corners.
Intermittent failure, the system is OK at this
time.
Replace the yaw rate-lateral acceleration
sensor (see page 19-169).
