  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the ground circuit terminals listed below and ground:
    • Terminal 11 (JL4)
    • Terminal 38 (w/o JL4)
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Verify that a test lamp illuminates between the B+ circuit terminals listed below and ground:
    • Terminal 1 (JL4)
    • Terminal 25 (w/o JL4)
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the EBCM.
