Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Ignition ON, test for less than 1 volt between the 12-volt reference circuit terminal of the appropriate sensor listed below and ground:
    • LF Sensor circuit terminal 26
    • RF Sensor circuit terminal 9
    • LR Sensor circuit terminal 6
    • RR Sensor circuit terminal 7
    • If greater than the specified range, test the 12-volt reference circuit for a short to voltage.
  3. Test for less than 1 volt between the signal circuit terminal of the appropriate sensor listed below and ground:
    • LF Sensor circuit terminal 5
    • RF Sensor circuit terminal 10
    • LR Sensor circuit terminal 27
    • RR Sensor circuit terminal 8
    • If greater than the specified range, test the signal circuit for a short to voltage.
  4. Ignition OFF, test for infinite resistance between the 12- volt reference terminal of the appropriate sensor circuit listed below and ground:
    • LF Sensor circuit terminal 26
    • RF Sensor circuit terminal 9
    • LR Sensor circuit terminal 6
    • RR Sensor circuit terminal 7
    • If less than the specified value, test the 12-volt 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:
    • LF Sensor circuit terminal 5
    • RF Sensor circuit terminal 10
    • LR Sensor circuit terminal 27
    • RR Sensor circuit terminal 8
    • If less than the specified value, test the signal circuit for a short to ground.
  6. Ignition OFF, disconnect the harness connector at the appropriate WSS.
  7. Test for less than 2 ohms between the appropriate 12-volt reference circuit terminals listed below:
    • LF Sensor circuit terminal 26 at the EBCM harness connector, and terminal 2 at the WSS harness connector
    • RF Sensor circuit terminal 9 at the EBCM harness connector, and terminal 2 at the WSS harness connector
    • LR Sensor circuit terminal 6 at the EBCM harness connector, and terminal 2 at the WSS harness connector
    • RR Sensor circuit terminal 7 at the EBCM harness connector, and terminal 2 at the WSS harness connector
    • If greater than the specified range, test the 12-volt reference circuit for an open or high resistance.
  8. Test for less than 2 ohms between the appropriate signal circuit terminals listed below:
    • LF Sensor circuit terminal 5 at the EBCM harness connector, and terminal 1 at the WSS harness connector
    • RF Sensor circuit terminal 10 at the EBCM harness connector, and terminal 1 at the WSS harness connector
    • LR Sensor circuit terminal 27 at the EBCM harness connector, and terminal 1 at the WSS harness connector
    • RR Sensor circuit terminal 8 at the EBCM harness connector, and terminal 1 at the WSS harness connector
    • If 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.
