Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the X83 Auxiliary Audio Input and disconnect the X2 harness connector at the A11 Radio, ignition ON.
- Test for less than 1 V between each X83 Auxiliary Audio Input harness connector terminal listed below and ground:
- Left auxiliary audio signal circuit terminal 1
- Right auxiliary audio signal circuit terminal 4
- Auxiliary audio common signal circuit terminal 3
- If 1 V or greater
Repair the short to voltage on the circuit.
- Go to next step: If less than 1 V
- Test for infinite resistance between each X83 Auxiliary Audio Input harness connector terminal listed below and ground:
- Left auxiliary audio signal circuit terminal 1
- Right auxiliary audio signal circuit terminal 4
- Auxiliary audio common signal circuit terminal 3
- If less than infinite resistance
Repair the short to ground on the circuit.
- Go to next step: If infinite resistance
- Test for less than 2 Ω between each harness connector terminal listed below end to end.
- X83 Auxiliary Audio Input- terminal 1 and A11 Radio terminal 3 X2
- X83 Auxiliary Audio Input - terminal 4 and A11 Radio terminal 1 X2
- X83 Auxiliary Audio Input - terminal 3 and A11 Radio terminal 2 X2
- If 5 Ω or greater
Repair the open/high resistance in the circuit.
- Go to next step: If less than 5 Ω
- Replace the X83 Auxiliary Audio Input. Connect all harness connectors.
- Connect the EL-50334-20 Multi-Media Interface Tester (MIT) to the X83 Auxiliary Audio Input 3.5 mm (1/8 in.) input jack and select the AUX test mode.
- Verify the audio from the EL-50334-20 Multi-Media Interface Tester (MIT) is heard through the infotainment system while operating the system to play audio from the test tool.
- If audio is not heard from the test tool
Replace the A11 Radio.
- Go to next step: If audio is heard from the test tool
- If audio is not heard from the test tool
- All OK.
