IBST-A099
IBST_a099_bridgeSwitchInitError
What does IBST-A099 mean?
Tesla alert code in the Integrated Brake System (IBST) module. Failure in Bridge Driver Supply Switch MOSFET. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. An ADC register Bit flipped or is stucked. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. RPS raw signals (sine and cosine): vector length too high. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit. Fault in the ADC peripheral detected. ECU internal fault, check wiring to the unit and/or re-flash. If problem continures after several power cycles, reolace unit.
