Condition
Some customers may comment that the Terms and Conditions (T&Cs) Agreement page
is displayed repetitively. This may also cause some of the following embedded apps to
lack some, or all, functionality:
• WiFi Hotspot
• Navigation
• Voice Recognition
• User Profile
When the condition occurs, it begins to create a backlog of messages it cannot send out
to the server. This process repeats, and the backlog continues to grow in number. The
backlog must be cleared to allow the current accepted T&Cs to be acknowledged at the
server.
Cause The cause of the condition may be a radio calibration anomaly.
Correction Reprogram the A11 radio. If necessary, clear any backlog of previous T&Cs messages.
Service Procedure
Note: Stable battery voltage is critical during
programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. Install a GM
Authorized Programming Support Tool to maintain
system voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12 V jumper or booster pack disconnected
from the AC voltage supply. DO NOTconnect a battery
charger.
1. Reprogram the A11 radio. Be sure both
programming events (Radio Programming and
USB File Transfer) are performed. Refer to A11
Radio: Programming and Setup in SI.
2. After completing the A11 radio programming, allow
the radio to process two full sleep cycles:
2.1. Turn off the ignition, open and close the driver
door and allow the vehicle to sit undisturbed
for 5 minutes.
2.2. Open the door, turn on the ignition and allow
the radio to complete its boot sequence.
Repeat step 2.1 for a total of two sleep cycles.
3. Verify the repair.
3.1. Is the OnStar LED on and green?
3.2. Does the OnStar app populate with Account
Information?
3.3. Access Apps in the Radio menu. Does the
Apps catalog populate with available apps?
3.4. If the answer is “No” to any question above,
contact the GM Technical Assistance Center,
selecting the OnStar team for further
instruction.
