TECHNICAL SERVICE BULLETIN

SUBJECT

SOS Inactive Warning Message, No Communication with TCU 

SITUATION

A check control message stating "SOS inactive" is displayed.

• The Telematics Control Unit (TCU) is NOT identified when performing a short test using the DISplus or GT1.
• If the SOS button is pressed, the call connects but the radio is not muted. The BMW Assist™ phone call audio comes from the emergency speaker.
• Bluetooth:  An approved Bluetooth® enabled handset, which previously worked, no longer connects to the vehicle. The Bluetooth menus for pairing a device to the vehicle are unavailable.
• RAD2 vehicles:  The BMW Assist icon and phone icon are missing from the Radio display.
• CCC vehicles:  Enable Services is grayed out.

CAUSE

• TCU Hardware failure
• MOST-Bus communication issue
• Incompatible handset paired to the vehicle

PROCEDURE

1. Duplicate the complaint.
2. Does the customer have a Bluetooth handset paired to the vehicle?
   • If no, proceed to step 3.
   • If yes, obtain the following information:
     • Manufacturer of the handset
     • Handset model number
     • Software number
     • Does the problem only occur when a handset is paired to the vehicle?
   NOTE: Pairing on an incompatible handset can have adverse effects. Please refer to the "Compatible Handset Information" section of this bulletin for more information.
3. Check the BMW Assist account status on DCSnet. The BMW Assist services expiration date and the TCU activation status can be checked on DCSnet under Service/Vehicle History Inquiry.
   • If the customer has an active BMW Assist services account, test the BMW Assist services following the information outlined in "Testing of BMW Assist Services" section of this bulletin.
4. Perform a short test using the DISplus or GT1.
5. Is the TCU identified when performing a short test?
   • If yes, proceed to step 6.
   • If no, are any other MOST-Bus modules identified?
     • If yes, check the power, ground and the MOST-Bus at the TCU.
     • If no, perform a MOST-Bus system analysis.
6. Work through any MOST-Bus communication faults. Diagnose and repair as necessary.
   • Check the MOST-Bus splice point for connection problems.
   • Check the MOST-Bus optical connection: for instance, were the OPS/OPPS heads connected?
   • If anything was retrofitted on the MOST-Bus (e.g., CDC, iPod, S-DARS, etc.), check the connections at the module that was retrofitted.
7. If you cannot duplicate the customer complaint and there are no MOST-Bus communication faults, refer to SI B84 16 07 (Erroneous SOS Inactive Warning Messages).
8. If the DISplus/GT1 cannot communicate with the TCU, the power and ground are OK at the TCU, and the MOST-Bus communication is OK, then the TCU should be replaced. Proceed to step 9.

COMPATIBLE HANDSET INFORMATION

Before the complaint can be addressed, the particular handset must be verified for compatibility with the respective Bluetooth system installed in the vehicle (e.g., BMW Assist with Bluetooth technology, BTUM, ULF). On vehicles equipped with BMW Assist with Bluetooth wireless technology, to confirm whether or not the phone is compatible, visit www.bmwusa.com/bluetooth  for a list of handsets that have passed BMW testing for compatibility. Note the following disclaimer on this website:

"This list is provided for reference only. The mobile phones listed here have passed compatibility tests as of the date of testing and meet or exceed minimum standards established by BMW. The list is not a warranty for phone performance or functionality. BMW makes no guarantees or warrantees as to the performance of each phone while connected to your BMW via Bluetooth Wireless Technology. Furthermore, software releases by BMW, the phone supplier or the wireless carrier dated after testing might alter compatibly results. While many phones are offered with Bluetooth Wireless Technology, not all phones support the necessary profiles to work with your BMW. BMW does not guarantee availability or functionality with all wireless carriers. Functions such as synchronizing the address book and transferring a call into or out of the vehicle may function differently from phone to phone".
