Why does the exact Tesla alert ID matter?
Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.
What does IBST-D142 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. Hardware error is reported by an underlying hardware driver while accessing the device for storing persistent data (reported for diagnostic purposes only, no system degradation). In the case of write access fails, the error is passed to the application using the NVM service. The application then performs the individual failure handling (e.g., system degradation and another failure is set). This additional failure entry only logs the root cause for hardware failure analysis.
