DAIMLERCHRYSLER COMMERCIAL BUSES issued a recall on the VII model

On certain transit buses, the Ultra Compact Module (UCM), which monitors the temperature and pressure across the exhaust Diesel Particulate Filter (DPF), can fail, causing an engine stall or the UCM's wiring harness to overheat and possibly ignite. This could result in a vehicle fire causing property damage and/or personal injury or death. Correction: Dealers will replace the 5 amp circuit breaker for the UCM with a 2 amp fuse to mitigate a failed UCM from subsequently causing a fire.
