And/or DTC P0AA500 (Hybrid/EV Battery Negative Contact Circuit Stuck Open) with symptom code 20483. Technical Background The contact surfaces of the HV contactors built into the battery junction box (BJB) can in rare cases oxidize if they are not used for a very long time or if the air humidity is extremely high. This oxidation concern can be rectified by the procedure mentioned in this TSB. Production Solution Not applicable. Service If the following DTC(s) are stored in the hybrid battery management control module, J840 (address word 008C): DTC P0AA200 (Hybrid/EV Battery Positive Contactor Circuit Stuck Open) with symptom code 20481 (Figure 1).

For the DTCs specified above, GFF suggests replacing the switching unit for the high-voltage battery (Battery Junction Box, SX6). Do not proceed according to GFF; instead, perform the following steps in the specified sequence: 1. Read out all measured value blocks relating to energy management from the gateway via GFF and make them available in GFF paperless. 2. Switch the ignition off and on again 5 to 10 times in a row (waiting for 5 seconds each time). 3. Erase all DTCs. 4. Perform a road test (EV mode with as many electrical consumers as possible switched on). Page 2 of 5 © 2021 Audi of America, Inc. All rights reserved.

Then re-assess whether the issue still occurs. If the issue does not occur again: Return vehicle to the customer. This condition is very rare and we do not expect the concern to repeat itself. If the issue occurs again: 1. Proceed according to the scan tool and replace the High-Voltage Battery Control Module SX6 (BJB). Follow all instructions in the scan tool and the Elsa repair manual. 2. Read out all measured value blocks relating to energy management from the gateway via GFF and make them available online (option 2 in GFF). 3. Switch the ignition off and on again 5 to a maximum of 10 times in a row (waiting for 5 seconds each time). 4. Erase all DTCs. 5. Perform a road test (EV mode with as many electrical consumers as possible switched on). 6. Then re-assess whether the issue still occurs. Warranty Claim Type: 110 up to 48 Months/50,000 Miles.
