Also written as IBST_D160 / IBST D160 / IBST_d160_assertionFail / ibst_d160_assertionfail
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-D160 mean?
Tesla diagnostic code in the Integrated Brake System (IBST) module. The iBooster assertion has failed according the ANSI C standard. When an assertion fails the following occurs: The failure is stored in the electrically erasable programmable ROM (EEPROM) (failure memory).The program flow is aborted, and the electronic control unit (ECU) is shutdown electrically (only in the power cycle when the assertion failed). In the next power cycle, the already failed assertion is detected, and the system is shutdown hydraulically to read the failure memory. Assertions are only active if NDEBUG is not set by the compiler (see also ANSI C standard).

Affected Tesla Models
What You May Notice
- Integrated Brake System alert: The iBooster assertion has failed according the ANSI C standard. When an assertion fails the following occurs: The failu
- 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-D160 is a diagnostic or informational code in the Integrated Brake System system. Typically no immediate action is required.
