1. Turn the ignition switch to ON (II).

2. Clear the DTC with the HDS.

3. Test-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. Inspect the appropriate magnetic encoder for

damage, debris, and correct installation.

21-11

Right-front

Remove the
driveshaft outboard
joint from the
appropriate wheel
hub (see page 18-15).

22-11

Left-front

23-11

Right-rear

Remove the hub
bearing unit
(see page 18-32).

24-11

Left-rear

Remove the debris from the magnetic

encoder, or replace the wheel bearing (front) or the
hub bearing unit (rear):

• Front: Replace the front wheel bearing (see page

18-18).

• Rear: Replace the rear hub bearing unit (see page

18-32).

Clean off debris from the appropriate

magnetic encoder surface on the wheel bearing or
the hub bearing unit, then go to step 1, and recheck.
If the DTC is still present, replace the appropriate
wheel bearing or hub bearing unit.

Is DT C 21-11, 22-11, 23-11, and/ or 24-11
indicated?

Is the magnetic encoder sur f ace OK ?

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. Check for DTCs with the HDS.

If DTC 61-01, 61-21, 61-22, 61-23, and/or

62-21 is indicated at the same time, check the
battery performance (see page 22-67), and do the
alternator and regulator circuit troubleshooting first
(see page 4-28). If DTC 61-01, 61-21, 61-22, 61-23,
and/or 62-21 is not indicated at the same time,
replace the yaw rate-lateral acceleration sensor
(see page 19-169).

Intermittent failure, the system is OK at this

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 60 seconds or more.

5. Check for DTCs with the HDS.

Replace the yaw rate-lateral acceleration

sensor (see page 19-169).

Intermittent failure, the system is OK at this

time.

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).
