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) for20 seconds or more.
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.
5. Operate any one of the four solenoids, as listed, in the ABS FUNCTION TEST five times with the HDS.
