- Revised Field Service Campaign for FCCC School Bus Chassis Park Brake Alarm. On certain vehicles, the park brake alarm software parameter may be disabled. With a disabled park brake alarm, if the driver turns off the ignition without setting the park brake, the park brake alarm may fail to emit an audible sound. REVISION: Due to a software parameter change that was not updated at the host, the SF633 repair provided during August 2021 through August 2022 was not adequate. The host has been updated and the repair will now rectify the issue. SF633 has been re-released with a new termination date of September 30, 2023.
