1. Turn the ignition switch to ON (II).
2. Turn the steering wheel left and right 90 degrees or
more. Check the STEERING ANGLE in the VSA
DATA LIST with the HDS.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the
steering angle sensor 5P connector and the VSA
modulator-control unit 37P connector. Refer to
intermittent failures troubleshooting (see page
19-98).

3. Turn the ignition switch to LOCK (0).
4. Disconnect the steering angle sensor 5P connector.
5. Disconnect the VSA modulator-control unit 37P connector (see step 2 on page 19- 171).6. Check for continuity between body ground and
steering angle sensor 5P connector terminals No. 2
and No. 4 individually.
Repair short to body ground in the wire
between the steering angle sensor and the VSA

Go to step 3.
3. Check that the appropriate wheel speed sensor is properly mounted (see page 19-173).
Go to step 4.
Reinstall the wheel speed sensor, and check
the mounting position (see page 19- 173).
4. Turn the ignition switch to ON (II).
5. Clear the DTC with the HDS.
6. Test-drive the vehicle at 10 km/h (7 mph) for 20 seconds or more.
NOTE: Drive the vehicle on a straight section of
road, not on a lift. 7. Check for DTCs with the HDS.
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.
If any other DTCs are indicated, go to the
indicated DTCs troubleshooting. If DTCs are not
indicated, intermittent failure, the system is OK at
this time.
