Circuit/System Testing

Auxiliary Audio Input Jack

  1. Ignition OFF, disconnect the X1 harness connector at the X83 auxiliary audio input.
  2. Ignition ON, radio ON, test for 2.5-3.5 V between the auxiliary detection terminal 5 and ground.
    • If less than specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the A11 radio.
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the A11 radio.
  3. Ignition OFF, disconnect the X1 harness connector at the radio. Test for infinite resistance between the circuits listed below and ground:
    • Auxiliary Audio Common Circuit Terminal 23
    • Left Auxiliary Audio Circuit Terminal 24
    • Right Auxiliary Audio Circuit Terminal 10
    • If not the specified value, test the signal circuit for a short to ground.
  4. Test for less than 5 Ω between the A11 radio X1 terminal 24 and the X83 auxiliary audio input terminal 1.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  5. Test for less than 5 Ω between the A11 radio X1 terminal 10 and the X83 auxiliary audio input terminal 2.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  6. Test for less than 5 Ω between the A11 radio X1 terminal 23 and the X83 auxiliary audio input terminal 3.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  7. Reconnect the X1 harness connector at the A11 radio.
  8. Ignition ON, test for less than 1 V between the circuits listed below and ground:
    • Auxiliary Audio Common Circuit X83 Auxiliary Audio Input Terminal 3
    • Left Auxiliary Audio Circuit X83 Auxiliary Audio Input Terminal 1
    • Right Auxiliary Audio Circuit X83 Auxiliary Audio Input Terminal 2
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the A11 radio.
  9. If all circuits test normal, replace the X83 auxiliary audio input and reconnect all harness connectors. Connect and operate the portable audio playback device. If audio cannot be heard from the device, replace the A11 radio.

USB Port

  1. Ignition OFF, disconnect the X1 harness connector at the X83 auxiliary audio input.
  2. Test for less than 5 Ω between the ground circuit terminal 4 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 6 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Ignition OFF, reconnect the X1 harness connector at the X83 auxiliary audio input.
    5. NOTE:

    USB cables and adapters for the following tests are found in the EL-50334-50  USB Cable and Adapter Kit.

  5. Disconnect the USB cable connection at the X83 auxiliary audio input and at the X216 I/P to floor console harness USB connector.
  6. Connect the EL-50334-2  Type A female to Mini B male USB Cable to the X83 auxiliary audio input and the I/P side of the X216 I/P to floor console harness USB connector.
  7. Ignition ON, radio ON, connect a USB device to the X83 auxiliary audio input Verify the infotainment system does not switch to USB as the audio source.
    • If the infotainment system switches to USB as the audio source, replace the console side USB cable.
  8. Ignition OFF, reconnect the vehicle USB cable to the X83 auxiliary audio input.
  9. Disconnect the USB cable at the A11 radio.
  10. Connect the EL-50334-1  Type A male to Mini A male USB Cable to the A11 radio and the console side of the X216 I/P to floor console harness USB connector.
  11. Ignition ON, radio ON, connect a USB device to the X83 auxiliary audio input Verify the infotainment system does not switch to USB as the audio source.
    • If the infotainment system switches to USB as the audio source, replace the I/P side USB cable.
  12. If all circuits test normal, replace the X83 auxiliary audio input and reconnect all harness connectors. Connect and operate the USB device. If audio is still not heard from the device, replace the A11 radio.
