Overview

The audio system combines a number of the networks and modules on the vehicle to provide a full entertainment package to the passengers.

Because of the complexity of the system, there are different techniques involved in diagnosing the system, as the networks used include controller area network (CAN) and media oriented system transport (MOST).

For information on the description and operation of the audio system, refer to the relevant section of the workshop manual. For information on diagnosis of the networks, refer to the Network Communications section of the workshop manual.

Satellite Digital Audio Radio Service (SDARS) diagnosis

Overview

The following information is intended to aid in the diagnosis of basic faults with the satellite radio system.

The diagnostic trouble codes are the main source of information in diagnosing other than basic faults.

There are five conditions which may affect the available channels:

A: No signal available

The signal is not reaching the module.

The vehicle must have clear line of sight to a satellite, which means being outside and having no blockages between the vehicle and the satellite.

:
  If the vehicle is outside America, this is the only condition which will be possible.

B: More than 6 months without subscribing

There is a 6 month free period of channel 184 being broadcast to allow testing of the system.

After this period, no channels can be received, and an unsubscribed message will be displayed.

C: Less than 6 months without subscribing

This will allow the vehicle to receive channel 184 only, all other channels will display unsubscribed.

D: Subscribed to the family package

All channels should be audible, but adult content channels will be blocked, and the message unsubscribed will be shown on these channels.

E: Subscribed to the full package

All channels should be available, with the exception of some pay channels.

In this case, the message unsubscribed will be shown on these channels.

System testing

Tune to channel 184 (this is usually the default channel for all presets).

Select the direct channel input feature by pressing the "#" key.

This will allow the audio to be routed to the speakers if condition C, D or E exist.

If condition B exists, a subscription will have to be made.

. Are other systems affected?
  The most common symptom would be the loss of audio from other entertainment features, although the display sticking on the logo screen is a good indicator of a MOST issue.
