Unit Check (Quick Check): XM
WARNING: This page is about a different variant/trim than selected.
- This diagnosis tests the GA-Net Bus line to the XM receiver.
- If the Connection is NG, first check for loose terminals at the navigation unit and the audio unit connections. Next check for an open or short in the GA-Net Bus line between the XM receiver and the audio unit. If the wire has an open or short, replace the affected shielded harness.
