瀚慖f less than the specified value, test the 12 V reference circuit for a short to ground.

5. Test for infinite resistance between the following signal circuit terminal of the appropriate sensor circuit listed below and ground.

* Left Front Sensor circuit terminal 34

* Right Front Sensor circuit terminal 6

* Left Rear Sensor circuit terminal 20

* Right Rear Sensor circuit terminal 31

瀚慖f less than the specified value, test the signal circuit for a short to ground.

6. Ignition OFF, disconnect the harness connector at the appropriate wheel speed sensor.

7. Test for less than 2 ohm between the appropriate 12 V reference circuit terminals listed below.

* Left Front Sensor circuit terminal 21 at the EBCM harness connector, and terminal 2 at the wheel speed sensor harness connector

* Right Front Sensor circuit terminal 18 at the EBCM harness connector, and terminal 2 at the wheel speed sensor harness connector

* Left Rear Sensor circuit terminal 33 at the EBCM harness connector, and terminal B at the wheel speed sensor harness connector

* Right Rear Sensor circuit terminal 19 at the EBCM harness connector, and terminal B at the wheel speed sensor harness connector

瀚慖f greater than the specified range, test the 12 V reference circuit for an open or high resistance.

8. Test for less than 2 ohm between the appropriate signal circuit terminals listed below.

* Left Front Sensor circuit terminal 34 at the EBCM harness connector, and terminal 1 at the wheel speed sensor harness connector

* Right Front Sensor circuit terminal 6 at the EBCM harness connector, and terminal 1 at the wheel speed sensor harness connector

* Left Rear Sensor circuit terminal 20 at the EBCM harness connector, and terminal A at the wheel speed sensor harness connector

* Right Rear Sensor circuit terminal 31 at the EBCM harness connector, and terminal A at the wheel speed sensor harness connector

瀚慖f greater than the specified range, test the signal circuit for an open or high resistance.

9. If all circuits test normal, replace the appropriate wheel speed sensor. If the DTC resets replace the EBCM.
