1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it ON (II) again.
4. Check for DTCs with the HDS.

Is DTC 11-13, 13-13, 15-13, and/or 17-13 indicated?

YES -Go to step 5.

NO -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 ).

5. Turn the ignition switch to LOCK (0).
6. Disconnect the VSA modulator-control unit 37P connector.
7. Check for continuity between the appropriate VSA modulator-control unit 37P

connector wheel speed sensor +B and GND terminals (see table), then check
for continuity between the same terminals and reverse the positive and negative
tester probes.

Control Unit 37P Connector Wheel Speed Sensor +B

Is there continuity in both directions?

YES -Go to step 8.

NO -If there is no continuity in either direction, go to step 10. If there is
continuity in only one direction, go to step 12.

8. Disconnect the appropriate wheel speed sensor 2P connector.
9. On the sensor side, check for continuity between appropriate wheel speed

sensor 2P connector terminals No. 1 and No. 2, then check for continuity
between the same terminals and reverse the positive and negative tester probes.
