23-195
LOADING XM radio is acquiring audio or
program information. Wait until the radio receives the information.
(XM) OFF AIR XM channel not in service. Try another XM channel.
(XM) NO SIGNAL Loss of signal. Both terrestrial and satellite antennas have lost
signal. Park the vehicle outside with a clear
view of the southern horizon.
(XM) UPDATING XM radio is receiving
information update from the
network. This message disappears once the update
finishes.
(XM) CHECK ANTENNA XM antenna error. Repair open or short in the satellite antenna.
Substitute the XM antenna with a known-good
one, and recheck. If the error is gone, replace
the original XM antenna. If the error is still
present, replace the antenna lead.
(XM) ANTENNA ERROR
No signal from XM. Check a known-good vehicle with XM radio. If
the known-good vehicle has the same
symptoms, contact XM Satellite Radio at
800-852-9696.
CODE ERROR 1 Anti-theft code mismatch
(1 try). Enter the correct anti-theft code.
CODE ERROR E Anti-theft code mismatch
(10 try). Remove the No. 23 (10 A) fuse in the under-
hood fuse/relay box, then reinsert it. You will
have 10 more tries to enter the correct anti-
theft code.
NOTE: Do XM error codes checks with the vehicle parked outside with a clear view of the southern horizon.
