[NEW] CORRECTION

[NEW] PROCEDURE
Cause #1
A. Ask the customer where (location) and how often it is happening (can it be reproduced all the time?)
^ Try a similar vehicle for verification at the same location and time.
If it acts the same way, then the functionality is normal and no further steps have to be taken.
^ For information on SIRIUS/XM satellite radio functionality, please refer to Service Information B65 02 05.
Causes #2 through #5
B. If it is acting differently, follow these steps:
^ Check if the installed SDARS roof antenna (including the SDARS antenna cable) is defective by connecting an aftermarket SIRIUS antenna and
retest.
^ Check the connectors on the SDARS antenna (shark fin) and on the SDARS receiver.
^ If there is no problem found on the SDARS antenna including the SDARS antenna cable and connectors perform step C.
C. Perform diagnosis using ISTA (Integrated Service Technical Application), and troubleshoot any faults related to the SIRIUS/XM satellite radio
system.
