IBST-D020
IBST_d020_voltPreRegModeFld
What does IBST-D020 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. The voltage pre-regulator mode in the application-specific integrated circuit (ASIC) does not fit to the software (SW) configuration. The ASIC monitors the hardware (HW) pre-regulator configuration and compares it to the flashed SW configuration. The presence of this alert indicates the SW configuration of the pre-regulator does not fit the ASIC HW configuration or there is a HW malfunction t in the ASIC voltage pre-regulator path.?
