What’s wrong with it?
THIS CONDITION WILL PERMIT HOT EXHAUST GASES TO EXIT THE VEHICLE TAILPIPE, INCREASING THE RISK OF MELTING OR BURNING OF NEARBY SURFACES, OR A FIRE.
CUMMINS IS RECALLING 912 ISB CM2150, ISC CM2150, ISL CM2150, ISM CM876, AND ISX CM871 MODEL DIESEL ENGINES INSTALLED AS ORIGINAL EQUIPMENT IN VARIOUS EMERGENCY VEHICLES.
THE VEHICLES MAY BE DESIGNED WITH A HARD WIRED, DASH-MOUNTED SWITCH THAT ENABLES THE VEHICLE OPERATOR TO INHIBIT AFTERTREATMENT DIESEL PARTICULATE FILTER REGENERATION IN ENVIRONMENTS WHERE THE OPERATOR BELIEVES IT MAY BE UNSAFE FOR ELEVATED EXHAUST TEMPERATURES.
DUE TO AN ISSUE WITH THE LOGIC IN THE ECM SOFTWARE IN THESE ENGINES, THE SWITCH MAY NOT FUNCTION CORRECTLY, LEADING THE OPERATOR TO BELIEVE THAT THE SWITCH IS IN “INHIBIT” MODE WHEN IT IS NOT.

What the record doesn’t say
- NHTSA’s recall file doesn’t say whether anyone was hurt.
- Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
- How many have been returned or fixed isn’t in the notice.
