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-D022 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. This alert indicates that the ASW configuration took too long. There is a mismatch between the state management configuration and the controllers. The current state stays in an initialized state (0xFF). It is configured in the STM, but it is not used by the controllers. The current states stay in the initialized state for a longer period of time without being used by the corresponding component.
