A 09/02/06 '07-'09 (DH/D1) '07-'09 (D1/DH) MODELS '07 (DH/D1/DC) '06-'07 (DH/D1/DC) Diesel Particulate Filter: Diagnosis and repair of DTC's P1451, P200C, P242F or black smoke from exhaust. This bulletin applies to vehicles equipped with a Cummins 6.7-liter engine (sales code ETJ). The customer may experience a malfunction indicator lamp (MIL) illumination, warning chime and an overhead electronic vehicle information center (EVIC) message regarding the aftertreatment system and/or black smoke from the exhaust and/or a no start condition. Further investigation by the technician may reveal that the MIL illumination and/or EVIC message is due to one or more of the following diagnostic trouble codes (DTC''s): P1451 - Diesel Particulate Filter - System Performance P242F - Diesel Particulate Filter Restriction - Ash Accumulation P200C - Diesel Particulate Filter Over Temperature - Bank 1. This bulletin provides revised diagnostic and repair procedures for DTC's P1451, P200C, P242F, black smoke from the exhaust, or a no start condition due to a nonfunctional or plugged diesel particulate filter (DPF). Diesel particulate filter Stationary DeSoot. This bulletin applies to D1/DH vehicles equipped with a 6.7-liter Cummins diesel engine (sales code ETJ). Mobile DeSoot still applies to DC/DM vehicles equipped with the 6.7-liter Cummins diesel engine (sales code ETJ). Stationary DeSoot has replaced Mobile DeSoot as the repair for Diagnostic Trouble Codes P1451 and P2463. This bulletin provides the procedure to perform Stationary DeSoot. This new procedure allows running the DeSoot in a secured area with the vehicle unattended. Stationary DeSoot can only be performed when the diesel particulate filter has exceeded a specified soot threshold. The Diagnostic Scan Tool will not allow the procedure to operate unless the threshold has been exceeded. If the vehicle does not have an active P1451, the soot in the Diesel Particulate Filter is at a normal level and a scan tool initiated DeSoot is not needed. SUBJECT/DESCRIPTION 5.9-liter and 6.7-liter Cummins diesel engines - correct low and ultra-low sulfur highway diesel fuel use. This bulletin involves a discussion regarding the correct diesel fuel to use for either the 5.9-liter or the 6.7-liter Cummins diesel engine (sales code ETH and ETJ respectively). Dodge Ram trucks equipped with the 6.7-liter Cummins Turbo-Diesel engine are required by Federal law to be fueled with ultra-low sulfur diesel fuel (model year '07.5). Early production 2007 Dodge Ram trucks equipped with the 5.9 Cummins Turbo Diesel engine are allowed by Federal law to be fueled with low sulfur diesel fuel, and are encouraged to fuel with ultra-low sulfur diesel fuel. The new ultra-low sulfur highway diesel fuel enables vehicles equipped with the advanced emissions control devices to achieve more stringent U/S EPA vehicle emissions standards. Fuel and fuel filtering requirements for Cummins 5.9-liter and 6.7-liter engines. This bulletin supersedes technical service bulletin 14-007-06, dated August 25, 2006. This information-only bulletin involves a discussion regarding fuel system requirements. The bulletin applies to vehicles equipped with a 5.9-liter High Output or a 6.7-liter Cummins Turbo Diesel engine (sales codes ETH or ETJ respectively) that were built on or after March 07, 2006. Bulletin highlights follow: For the diesel engine system to operate at its peak performance, a high level of fuel quality must be maintained. Emission control and fuel delivery systems have advanced significantly. Care must be taken to ensure that the fuel that is delivered to the engine fuel injection system is of the highest quality possible and free of contaminants. Significant components to fuel quality are: the initial quality of the fuel (as dispensed from the service station fuel pump or bulk storage), on-vehicle fuel storage, and the on-vehicle fuel filtering of the diesel fuel prior to the fuel injection process.
