Customer states: The warning message “Emergency call function: malfunction! Restricted functionality. Please contact Service” appears in the instrument cluster (Figure 1). Figure 1. The warning message is shown in the instrument cluster. Workshop findings: The following DTC may be stored in the gateway control module, J533 (address word 0019) as static or intermittent: DTC B191604 (Backup battery Faulty). Technical Background Incorrect software parameter for the connected Gateway’s back-up battery charge monitoring. The system must be reset by performing a manual discharge of the connected Gateway’s backup battery. Production Solution The part is no longer used in production. Service 1. Perform a manual discharge of the connected gateway’s backup battery by removing constant power (KL30) and accessory power (KL15), while KL15 is switched on. This will force the connected gateway to draw power from the backup battery, lowering the voltage of the backup battery. Several discharge cycles may be needed for the voltage of the backup battery to fall within the specified parameters. Page 2 of 6 © 2021 Audi of America, Inc. All rights reserved.

Note: The steps for the manual discharge, 4 through 8, are to be performed with the engine OFF, and without a 12V charger on the vehicle. 2. Gain access to fuse panel SB, located behind the driver’s side footwell cover. Consult the Elsa Repair Manual for instructions on accessing fuse panel SB. 3. Locate the two fuses which supply constant power (KL30) and accessory power (KL15) to the connected gateway. Consult the wiring diagram or Owner’s Manual for the fuse location and size. 4. Ensure that accessory power (KL15) is ON. 5. Remove the two fuses identified in Step 3. 6. Wait 30 seconds with both fuses removed. 7. Reinstall the two fuses. 8. Turn off accessory power (KL15). 9. Repeat steps 4 through 8 six additional times. This will result in a total of seven discharge cycles. 10. Following seven discharge cycles, clear the fault memory for the connected gateway module: In ODIS GFF, recheck the fault memory of the connected gateway. The DTC should now be passive/sporadic and should not return after clearing the fault memory. If the fault does not clear and is marked as active/static, then replace the connected gateway’s backup battery. Consult the Elsa Repair Manual for instructions on replacing the connected gateway’s backup battery. Consult the parts catalog for the correct part number of the connected gateway’s backup battery.
