DTC 11: Right-Front Wheel Speed Sensor Circuit Malfunction; DTC 13: Left-Front Wheel Speed Sensor Circuit Malfunction; DTC 15: Right-Rear Wheel Speed Sensor Circuit Malfunction; DTC 17: Left-Rear Wheel Speed Sensor Circuit Malfunction

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)  ).
  1. Turn the ignition switch to ON (II).
  2. Clear the DTC with the HDS.
  3. Turn the ignition switch to LOCK (0).
  4. Test-drive the vehicle at 19 mph (30 km/h) or more.
    NOTE: Drive the vehicle on the road, not on a lift.
  5. Check for DTCs with the HDS.

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

    YES  -Go to step 6.

    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 47P connector. Refer to intermittent failures troubleshooting (see DIAGNOSTIC TROUBLE CODE (DTC)  ).

  6. Turn the ignition switch to LOCK (0).
  7. Disconnect the VSA modulator-control unit 47P connector (see step  2).
  8. Check for continuity between body ground and the appropriate wheel speed sensor +B and GND terminals of the VSA modulator-control unit 47P connector individually (see table).

If the VSA modulator-control unit was updated, substitute a known-good VSA modulator-control unit, (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ) then retest. If the VSA modulator-control unit was substituted, Go to step  1.

    NO  -If the VSA modulator-control unit was updated, troubleshooting is complete. If the VSA modulator-control unit was substituted, replace the original VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ). If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
