What's wrong?
The hydraulic brake modulator on the 2021-2022 Blue Bird Vision School Bus and All American School Bus is the brake control unit that helps manage hydraulic braking and electronic stability control. ESC uses vehicle information to help the bus stay stable during hard steering or braking. For that system to work as designed, the control unit needs the correct vehicle-specific programming.
On affected buses, the hydraulic brake control unit was not programmed to the right vehicle parameters during assembly. That means the ESC system is not tuned to the bus it is installed on. During an accident, ESC can fail to operate as designed, which raises the risk of injury to occupants.
There is no audible warning before this programming problem affects ESC operation. The warning sign Blue Bird identified is an ESC light that comes on at random, including while driving straight on dry pavement.
Who's affected?
Covers Vision School Bus and All American School Bus models across the 2021 and 2022 model years, all tied to the hydraulic brake modulator used for electronic stability control.
