Pierce Saber — 09V389000
Summary
PIERCE IS RECALLING CERTAIN MODEL YEAR 2008 AND 2009 FIRE TRUCKS MANUFACTURED BETWEEN APRIL 1, 2008 AND SEPTEMBER 30, 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.
Consequence
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.
Remedy
PIERCE IS WORKING WITH CUMMINS TO REPAIR THE ENGINES. CUMMINS IS CONDUCTING THIS CAMPAIGN AND WILL PROVIDE THE REMEDY FREE OF CHARGE. PLEASE SEE CUMMINS RECALL CAMPAIGN 09E-046. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING OCTOBER 2009. OWNERS MAY CONTACT CUMMINS AT 1-800-DIESELS (1-800-343-7357) OR PIERCE AT 1-920-832-3000.
