  3. Disconnect the 20P connector (B) from the roof console (C)
  4. Inspect the connector and socket terminals to be sure they are all making good contact
    • If the terminals are bent, loose or corroded, repair them as necessary and recheck the system
    • If the terminals look OK, go to step 5
  5. With the connector still disconnected, do these input tests at the following connector
    • If any test indicates a problem, find and correct the cause, then recheck the system
    • If all the input tests prove OK, go to step 6
