IBST-D029
IBST_d029_bmcShortedGateTest
What does IBST-D029 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. There is a short circuit in B6 bridge, bridge transistor, or motor coil. There is an overcurrent detected while switching on the High-side and Low-side transistors of different phases. This indicates a shorted bridge transistor, motor coil, or there is a short between the actuation lines of different bridge transistors.
Original Description
There is a short circuit in B6 bridge, bridge transistor, or motor coil. There is an overcurrent detected while switching on the High-side and Low-side transistors of different phases. This indicates a shorted bridge transistor, motor coil, or there is a short between the actuation lines of different bridge transistors.
Severity Notes
IBST-D029 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
