Why does the exact Tesla alert ID matter?

Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.

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.

Affected Tesla Models

Model SModel XModel 3Model Y

What You May Notice

  • Integrated Brake System alert: There is a short circuit in B6 bridge, bridge transistor, or motor coil. There is an overcurrent detected while switchin
  • No noticeable change in braking performance under normal driving

How to Diagnose and Resolve

  1. 1 Reboot the vehicle
  2. 2 Monitor over the next few drives
  3. 3 Schedule service if the alert reappears

Severity Notes

IBST-D029 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
