Is there continuity between any of the terminals?

YES -There is a short in the wires between the audio unit and the XM receiver. Replace the affected shielded harness.

NO -Substitute a known-good audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ), and recheck. If the symptom/indication goes away, replace the original audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ). If the symptom is still present, substitute a known-good XM receiver (see ACURALINK CONTROL UNIT (XM RECEIVER) REMOVAL/INSTALLATION ), and recheck. If the symptom/indication goes away, replace the original XM receiver (see ACURALINK CONTROL UNIT (XM RECEIVER) REMOVAL/INSTALLATION ).
