Circuit/System Testing

Ignition OFF, disconnect the X1 harness connector at the X83 Auxiliary Audio Input.
Test for less than 10 Ω between the ground circuit terminal 3 and ground.
- If 10 Ω or greater
1. Ignition OFF.
2. Test for less than 2 Ω in the ground circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 Ω
Verify that a test lamp illuminates between the B+ circuit terminal 1 and ground.
- If the test lamp does not illuminate
1. Ignition OFF, remove the test lamp.
2. Test for less than 2 Ω in the B+ circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
- Go to next step: If the test lamp illuminates
Verify the USB cable is properly connected at all components and any in-line connections, and there is no damage to the cable or connections.
- If connection problems or cable damage is noted.
  Perform the appropriate repair or replacement to correct any issues.
- Go to next step: If no connection problems or cable damage is noted.
Replace the X83 Auxiliary Audio Input. Connect all harness connectors.
Ignition ON, infotainment system ON.
Connect a compatible USB device to the USB port and attempt to play audio.
Verify audio is heard through the infotainment system while operating the USB device.
- If audio is not heard
1. Replace the USB cable assembly.
2. Connect a compatible USB device to the USB port and attempt to play audio.
3. Verify audio is heard through the infotainment system while operating the USB device.
  - If audio is not heard, replace the A11 Radio.
  - Go to next step: If audio is heard.
4. All OK.
- Go to next step: If audio is heard
All OK.
