Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

NOTE:
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1 Verify the customer concern.
2 Visually inspect for obvious signs of mechanical or electrical damage.





3 If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4 If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

Satellite Digital Audio Radio Service (SDARS) Diagnosis
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.

NOTE:
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.
1 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.
- If other systems are affected, check the entertainment circuits for loose or broken connectors, etc. Refer to the electrical guides.
2 If only the satellite radio system is affected, retrieve the DTCs from the module using the approved diagnostic system or a scan tool.
