  1. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down
  2. Disconnect the harness connectors at both of the P22 seatback video displays.
  3. Test for less than 10 Ω between the signal (-) circuits terminal 13 and ground at each display.
    • If 10 Ω or greater 
    1. Ignition OFF, disconnect the X3 connector at the A11 radio.
    2. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the A11 radio.
    • If less than 10 Ω 
  4. Ignition ON, radio ON, DVD playing.
  5. Test for 1-4 V between the signal (+) circuit terminal 12 and ground at each display.
    • If less than 1 V 
    1. Ignition OFF, disconnect the X3 harness connector at the A11 radio.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the A11 radio.
    • If greater than 4 V 
    1. Ignition OFF, disconnect the X3 harness connector at the A11 radio. Ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the A11 radio.
    • If between 1-4 V 
  6. Ignition OFF. Connect the harness connector at the P22E driver seatback video display.
  7. Ignition ON, radio ON, DVD playing.
  8. Test for 1-4 V between the signal (+) circuit terminal 12 and ground at the P22F passenger seatback video display.
    • If less than 1 V 

      Test or replace the P22E driver seatback video display

    • If greater than 4 V 

      Test or replace the P22E driver seatback video display

    • If between 1-4 V 
  9. Test or replace the P22F passenger seatback video display.
