Technical Background The warning message is generated by the telematics control module (ConBox Low for MY19), J949 (address word 0075) and is primarily used in two different scenarios: When there is a hardware or software malfunction of the control module. When there is a problem connecting to the Mobile Network Operator (AT&T). For problems related to the cellular network, the following DTC may be found in in the telematics control module, J949 (address word 0075): DTC U153E00 (Emergency call module and communication unit Recognition in mobile communications network not possible). This DTC will set the warning message upon the vehicle losing signal to the MNO (AT&T). However, depending on how long the signal is lost, the vehicle may require a full sleep cycle in order for the DTC to go sporadic and thus the warning message turned off in the cluster. For example: When a customer is on a long drive through an area where AT&T has little-to-no service, the warning message will be seen. If the vehicle is driven for 15-30 minutes with no service, then the vehicle may take a full hour before it retries to connect to the AT&T network. This is a requirement of AT&T. When the customer drives back into an area of service, the SOS light may stay off or red until the vehicle has been in a service area for up to one hour, or until the vehicle is turned off long enough for the vehicle systems to go through a sleep cycle. If the vehicle is operated continuously in an area with no service, then each time the vehicle is turned on the warning will be seen. This is true of when the vehicle is operated outside of the United States of America (Canada, Mexico, or overseas) since there is no supported cellular service in these areas. For certain MY20 vehicles, the telematics control module will be changed to a new ConBox High system. This new system will be updated so that the warning message is not seen or heard in the above two scenarios. Instead, the customer will need to rely on the SOS button LED status to understand if the system is functioning normally. Currently, there is no solution or change in behavior possible. Production Solution MY2020 series production software change to update the behavior of the telematics control module/ConBox High system when the vehicle experiences no MNO service.

Service If the DTC is found sporadic 1. Follow the recommended troubleshooting steps provided by GFF. 2. Please note the time and date when the DTC was set and document it in the repair order in the event the car returns for a repeat repair. 3. If the SOS button LED is green, then tell the customer that this warning is normal and is shown whenever the vehicle is driven in an area with little-to-no LTE service with AT&T. 4. No further analysis is required. If the DTC is found static 1. Follow the recommended troubleshooting steps provided by GFF. 2. Ignore the recommendation to replace the hardware if recommended by GFF. 3. If the SOS button LED is red or off, then gain access to the J949 - Emergency Call module (see Elsa). 4. Move the vehicle outside where it can get a full view of the sky for better cellular reception. 5. With the ignition off, remove the backup battery from the module and disconnect the main connector from the J949 - Emergency Call module. 6. Let the vehicle sit for 2-3 minutes. 7. Insert the backup battery into the telematics control module and reconnect the connector. 8. Turn the ignition on and let the vehicle sit for 5-10 minutes to allow the GPS system to gain a full 3D lock on the vehicle’s position. A GPS lock is required for the system to fully activate with the Audi connect backend. 9. Check for the SOS button LED to be green. If it isn’t green then check with someone at the dealership that has AT&T mobile service and see if the reception in the area is poor or if the cell phone is not able to access the internet using AT&T’s LTE service (try accessing a web page or YouTube on the phone). 10. If there is no issue with AT&T mobile reception on a cell phone then open a TAC contact for further assistance. Page 3 of 4 © 2019 Audi of America, Inc. All rights reserved.
