  1. Ignition OFF, disconnect the harness connector at the S70L Steering Wheel Controls Switch - Left.
  2. Ignition ON, test for B+ between the voltage reference circuit and ground.
    • If less than the specified value, test the voltage reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.
  3. Test for B+ between the voltage reference circuit and the signal circuit.
    • 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 Body Control Module.
  4. Ignition OFF, disconnect the X3 harness connector at the K9 Body Control Module.
  5. Test for infinite resistance between the signal circuit terminal 9 and ground.
    • If less than the specified value, test the signal circuit for a short to ground.
