- Ignition OFF, disconnect the X1 harness connector at the X83 auxiliary audio jack.
- Ignition ON, test for less than 1 V between the terminals listed below and ground:
- signal terminal 1
- signal terminal 2
- If greater than the specified value, test the circuit for a short to voltage. If the circuit tests normal, replace the A11 radio.
- 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.
- If all circuits test normal, replace the X83 auxiliary audio jack.
