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.
