What does IBST-A157 mean?
Tesla alert code in the Integrated Brake System (IBST) module. Scl: ESPiB3_pMC1 Invalid Value DTS off set is too high Confirmed Phase Current 2 out of range low. ECU internal fault, check wiring to the unit and or re-flash. If problem continures after several power cycles, reolace unit. The measured average coil resistivity is above the max threshold. Linear Position Sensor Channel 1 Sensor internal failure FW set in case of temperature degradation level1 Vpre was externally feed. Possible internal shortcircuit. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit.
