14. Turn the ignition switch to LOCK (0).
15. Substitute the appropriate wheel speed sensor with
opposite wheel speed sensor, or with a known-
good wheel speed sensor.
16. Reconnect all connectors.
17. Turn the ignition switch to ON (II).
18. Clear the DTC with the HDS.
19. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
20. 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.
Replace the original wheel speed sensor
(see page 19-173). NOTE: These DTCs may be caused by electrical
interference. Check for aftermarket devices installed in
the vehicle when these DTCs are indicated.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle. NOTE: Drive the vehicle on the road, not on a lift.
4. Check for DTCs with the HDS.
If DTC 12-12, 14-12, 16-12, or 18-12 is
indicated at the same time, do the DTC 12-12,
14-12, 16-12, or 18-12 troubleshooting first
(see page 19-121). If DTC 12-12, 14-12, 16-12, or
18-12 is not indicated, go to step 5.
If any other DTCs are indicated, go to the
indicated DTCs troubleshooting. If DTCs are not
indicated, there is an 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).Right-front Wheel Speed Sensor
