  3. Test for B+ between the B+ circuit terminal 1 and the signal circuit terminal 2.
    • If less than the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  4. Ignition OFF, disconnect the X1 harness connector at the K9 BCM.
  5. Test for infinite resistance between the signal circuit terminal 3 and ground.
