  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
  1. 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 ABS modulator-control unit 25P connector. Refer to intermittent failures troubleshooting.
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the wheel speed sensor 2P connector.
  1. Check for continuity between the appropriate ABS modulator-control unit 25P connector wheel speed sensor +B and GND terminals (see table).

NO -
Go to Step 14 .
  1. Turn the ignition switch to LOCK (0).
  1. Substitute the appropriate sensor with oppsite wheel speed sensor, or with a known-good wheel speed sensor.
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
  1. Check for DTCs with the HDS.
Is DTC indicated that is indicated in Step 4 ?
