Auxiliary Audio Input Jack with Multimedia Player Interface Module

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  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 T11 multimedia player interface module.
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the T11 multimedia player interface module.
  3. Ignition OFF, disconnect the X1 harness connector at the T11 multimedia player interface module. Test for infinite resistance between the circuits listed below and ground:
    • auxiliary audio common circuit terminal 3
    • left auxiliary audio circuit terminal 12
    • right auxiliary audio circuit terminal 13
    • If not the specified value, test the signal circuit for a short to ground.
  4. Test for less than 5 Ω between the T11 multimedia player interface module X1 terminal 12 and the X83 auxiliary audio input X1 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 T11 multimedia player interface module X1 terminal 13 and the X83 auxiliary audio input X1 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 T11 multimedia player interface module X1 terminal 3 and the X83 auxiliary audio input X1 terminal 3.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  7. Ignition OFF, disconnect the X1 harness connector at the A11 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.
  8. Test for less than 5 Ω between the A11 radio X1 terminal 24 and the T11 multimedia player interface module X1 terminal 14.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  9. Test for less than 5 Ω between the A11 radio X1 terminal 10 and the T11 multimedia player interface module X1 terminal 15.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  10. Test for less than 5 Ω between the A11 radio X1 terminal 23 and the T11 multimedia player interface module X1 terminal 4.
    • If greater than the specified value, test the signal circuit for an open/high resistance.
  11. Reconnect the X1 harness connector at the A11 radio.
  12. Ignition ON, test for less than 1 V between the circuits listed below and ground:
    • auxiliary audio common circuit T11 multimedia player interface module X1 terminal 4
    • left auxiliary audio circuit T11 multimedia player interface module X1 terminal 14
    • right auxiliary audio circuit T11 multimedia player interface module X1 terminal 15
    • If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the A11 radio.
  13. 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 T11 multimedia player interface module. If audio is still not heard from the device, replace the A11 radio.
