Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the EBCM.
  2. Ignition OFF, test for less than 1.0 ohm between ground circuit terminal 31 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 terminal 46 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ fuse is open, replace the BPMV.
  4. If all circuits test normal, replace the BPMV and verify DTC does not reset. If DTC reset, replace the EBCM.
