Orion VII: Emissions
Affects Orion VII · 2007 — about 100 vehicles.
The hazard
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.
