IBST-D077
IBST_d077_bcsFltCurrentHigh
What does IBST-D077 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. There is a faulty, positive current detected at the B6 bridge. A high transverse current is detected during inactivity of the half bridge while motor actuation is occurring or the current offset is too high outside of the motor actuation. This could indicate a current sensing circuit defect or defective B6 bridge transistors.
Original Description
There is a faulty, positive current detected at the B6 bridge. A high transverse current is detected during inactivity of the half bridge while motor actuation is occurring or the current offset is too high outside of the motor actuation. This could indicate a current sensing circuit defect or defective B6 bridge transistors.
Severity Notes
IBST-D077 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
