NO -Go to step 5.
- Turn the ignition switch to LOCK (0).
- Check XM antenna connector B (2P) at the XM receiver.
Is the XM antenna connector B (2P) connected?
YES -Go to step 7.
NO -Reconnect XM connector B (2P), and recheck the XM radio operation. If signals are restored, operation is normal. If signals are not restored, Go to step 7.
- Substitute a known-good XM antenna (see
AUDIO REMOTE SWITCH REPLACEMENT ).
Is the error massage gone?
YES -Replace the original XM antenna (see AUDIO REMOTE SWITCH REPLACEMENT ).
NO -Go to step 8.
- Disconnect the audio disc changer 13P connector (with navigation), and USB adapter unit connector A (14P) (if equipped).
