THE VEHICLES MAY BE DESIGNED WITH A HARD WIRED, DASH-MOUNTED SWITCH THAT ENABLES THE VEHICLE OPERATOR TO INHIBIT AFTER TREATMENT 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.

    I have owned two 2008 Peterbilt 340 with the ISC Cummins 335 horsepower engines in them and they have been in the shop more than they have run. These engines will not run properly more than 4 to six weeks at a time. This whole engine should be recalled. I have the RO’S from Cummins to prove what I have just said. Due to the problems I have expirenced with this product I am about to lose my bussiness. I have tried to work this situation out with Peterbilt and Cummins for the last 2 and half years to no avail. Any suggestions on what to do about this situation would greatly be appreciated.
