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-D188 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. The value for the pedal travel sensor (PTS) channel 1 offset could not be read from the electrically erasable programmable ROM (EEPROM) (failure memory). This indicates the EEPROM cell may be inoperative.
Original Description
