SDARS SIRIUS Radio Is Intermittently Inoperative

MODEL

All

Vehicles equipped with option 655 (Satellite Radio)

SITUATION

The SIRIUS/XM satellite radio is intermittently inoperative and "Acquiring" is displayed in certain cases.

[NEW] CAUSE

The antenna signal is missing for the following possible reasons:

1. The vehicle is in an area without connection to the SIRIUS/XM satellite.

^ Inside a building (parking garage, workshop, ...)

^ In tunnels

^ In a dense urban area surrounded by high-rise buildings

^ Under trees

^ In a valley or mountainous area

2. Defective SDARS antenna

3. Defective SDARS antenna cable

4. Defective connector on:

^ The SDARS antenna

^ The SDARS receiver

5. Internal fault in the SDARS receiver

[NEW] CORRECTION

Try to reproduce the complaint with the customer when possible. If it can be reproduced, follow the procedure below.

[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.
