What does IBST-A038 mean?
Tesla alert code in the Integrated Brake System (IBST) module. Continuous monitor of enable lines detected a missing(low) enable signal. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. ADC Selftest C5P detects failure. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. Operating System error (e.g. task overrun invalid parameters for OS API). ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. Load Dump Event Before or During BMS FSLT. Stack over or underflow. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. FW set in case of temperature degradation level2 The hydraulic enable line can't be switched off via the uC or via the system IC. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit.
