    • A11 Radio terminal 13 X3
    • A11 Radio terminal 14 X3
    • A11 Radio terminal 7 X3
    • A11 Radio terminal 17 X3
    • If 1 V or greater. 

      Repair the short to voltage on the circuit.

    • If less than 1 V. 
  3. Ignition OFF.
  4. Test for infinite resistance between the signal circuit terminals listed below and ground:

    • A11 Radio terminal 17 X3 and the X82 Audio/Video Input Adapter terminal 1
    • If 2 Ω or greater. 

      Repair the open/high resistance in the circuit.

    • If less then 2 Ω. 
  6. Replace the X82 Audio/Video Input Adapter.
  7. Connect all harness connectors. Ignition ON, radio ON.
  8. Verify the entertainment system displays video playing from a device connected to the X82 Audio/Video Input Adapter.
