What does IBST-A074 mean?
Tesla alert code in the Integrated Brake System (IBST) module. Find Idle Data can not be written in the find idle calibration routine in plant/service (RPS angle at Backward Bound and Idle and Lips IDs) Bridge driver shorted MOSFET detection error. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit.
