Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Test for less than 5 ohms of resistance between the ground circuit terminals 11 and 28 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminals 1 and 18 and ground.
    • If the test lamp does not illuminate, test the B+ circuits for a short to ground or an open/high resistance. If the circuits test normal and the B+ circuit fuses are open, test or replace the BPMV.
  4. Ignition ON, use the scan tool to perform the solenoid test.
    • If solenoid test failed, replace the EBCM.
  5. If all circuits test normal, replace the BPMV.
