Filing in context
This filing is one of 29 Mitsubishi notifications from 2023 in this archive. For scale, 4,351 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 8 months.
Issue
On large route buses equipped with EZGO/CB (a stop-assist system that activates when the center door is opened), the electrical circuit of the EZGO brake valve is incorrectly configured. When the center door is opened just before the vehicle comes to a stop, the front and rear brakes engage at a timing that differs from the designed sequence. This causes greater deceleration than intended and, in the worst case, may cause standing passengers to fall.
Corrective action
On all affected vehicles, correct the EZGO brake valve electrical circuit to the specified configuration.
