* Right front sensor circuit terminal 6

* Left rear sensor circuit terminal 5

* Right rear sensor circuit terminal 2

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 28 at the EBCM harness connector, and terminal 2 at the wheel speed sensor harness connector

* Right front sensor circuit terminal 17 at the EBCM harness connector, and terminal 2 at the wheel speed sensor harness connector

* Left rear sensor circuit terminal 4 at the EBCM harness connector, and terminal B at the wheel speed sensor harness connector

* Right rear sensor circuit terminal 3 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 29 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 5 at the EBCM harness connector, and terminal A at the wheel speed sensor harness connector

* Right rear sensor circuit terminal 2 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.
