Diagnosis and Trigger Conditions

This Audi eCall fault B200000 is primarily a software issue. The DTC B200000 is logged by the system without a valid underlying reason, indicating a need for optimized software versions for the Emergency Call Module and Communication Unit (ConBox). The TSB notes that the DTC setting conditions will be improved with these new software versions.

Repair Procedure Summary

The repair for the Audi eCall fault B200000 involves a two-part process to address the software anomaly. Technicians must ensure they are using the most current ODIS version, with a minimum requirement of ODIS > 2024.04.00.

Part 1: Diagnostic Check and DTC Erase

1. The technician will perform the program "J949 – Control Module for Emergency Call Module and Communication Unit, check control module" from the ODIS test plan. This program is automatically added when DTC B200000 is logged.
2. Alternatively, the function can be found in ODIS under Self-test >> Diagnostic capable systems >> 0075 – Control Module for Emergency Call Module and Communication Unit -J949- >> 0075 – Electrical components.
3. After running the program, the technician will verify if the DTC has been erased and if the "Emergency call function: malfunction!" message has disappeared from the instrument cluster. If the message persists, Part 2 of the repair procedure is necessary.

Part 2: Software Update (if needed)

For 2020 and 2021 model year vehicles, a comprehensive software package is available. This package is designed to fix several complaints, including the eCall fault. Details on distributing and using this software package are described in other service documents:

• Cluster 35 service update TSB 2067021 (for MY 2020 vehicles).
