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-D100 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. The error pin counter in the system Instrument Cluster (IC) does not increment error pin events or decouple bits that are not reset by the system IC. The failsafe logic test pulls the error pin in order to test the error pin event counter within the system chip. To prevent an electrical shutdown, which would disturb communication, during the provoked error pin event, the electrical decouple bit is set. It is also tested that the decouple bit gets reset.

What You May Notice
- Integrated Brake System alert: The error pin counter in the system Instrument Cluster (IC) does not increment error pin events or decouple bits that ar
- No noticeable change in braking performance under normal driving
How to Diagnose and Resolve
- 1 Reboot the vehicle
- 2 Monitor over the next few drives
- 3 Schedule service if the alert reappears
Severity Notes
IBST-D100 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
