Also written as IBST_D114 / IBST D114 / IBST_d114_motShaftShiftDetect / ibst_d114_motshaftshiftdetect
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-D114 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. There is an implausible motor angle at the backward bound. The actual motor angle at the backward bound does not match the backward bound angle comparison with the electrically erasable programmable ROM (EEPROM) value. This indicates that there is mechanical damage on the motor shaft or there was an electrical sensor malfunction.
Original Description
There is an implausible motor angle at the backward bound. The actual motor angle at the backward bound does not match the backward bound angle comparison with the electrically erasable programmable ROM (EEPROM) value. This indicates that there is mechanical damage on the motor shaft or there was an electrical sensor malfunction.
Affected Tesla Models
What You May Notice
- Integrated Brake System alert: There is an implausible motor angle at the backward bound. The actual motor angle at the backward bound does not match t
- 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-D114 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
