2008–2010 International 7600 Recall: Engine and Engine Cooling

The defect

NAVISTAR IS RECALLING CERTAIN MODEL YEAR 2008 AND 2010 EMERGENCY VEHICLES MANUFACTURED BETWEEN JUNE 12, 2007 AND JUNE 24, 2009, EQUIPPED WITH CUMMINS ISB CM2150, ISC CM2150, ISL CM2150, ISM CM876, AND ISX CM871 MODEL DIESEL ENGINES. 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.

The risk

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.
