Refer to MCI Service Bulletin 2947, located at for more information regarding ULSD. Failure to use ULSD fuel in 2007 EPA engines will result in component damage. LUBRICATION Diesel Engine Lubricating Oils Diesel engines require heavy-duty lubricating oils. Basic requirements of such oils are lubricating quality, high heat resistance, and control of contaminants. The only lubricating oil recommended for DDC S60 diesel engines is the CES or CES and viscosity grade SAE 15W-40. Synthetic Oils Synthetic oils may be used in DDC S60 engines, provided they are API licensed and meet the performance and chemical requirements of non---synthetic oils in the API Category III and viscosity grade SAE 15W-40. The use of synthetic oil does not extend the oil drain interval recommended by DDC. Table 1. Lubricating Oil Recommended API Service Code SAE Classification Grade CJ--4 15W--40 Summer / 5W--40 Winter Effective with unit number ( as well as 63876, 64301, 64302, 64342, 64343, 64371, and ), 2007 EPA engines must only use CJ- 4 engine oil. If the ambient temperature is above 15_F(-9.5_C), 15W40 oil must be used. If the ambient temperature is below 15_F (-9.5_C),5W40mustbeused. Failure to use CJ- 4 engine oil in 2007 EPA engines will reduce component life.

Before changing or adding coolant to the coach system, verify the type of coolant used in the coach. Power Cool Plus can be identified by it s red color. Power Cool can be identified by it s purple color. DO NOT mix Power Cool and Power Cool Plus coolant. Each contains different inhibitors which are not compatible. Mixing coolants will result in component failure. Figure 2.

The yellow Check Engine and red Stop Engine tell-tale lights no longer provide engine flash codes. Engine Code Retrieval The alphanumeric display, located at the bottom of the speedometer, displays the diagnostic trouble codes (Figure 3). The diagnostic trouble codes are displayed as J1939 SPN---FMI codes. A maximum of five codes can be listed at one time. These codes are logged in the ECM with the most severe or recent code listed first. The MODE switch allows the driver to scroll through active system messages, when the coach is at a complete stop. Pressing the SET switch will not clear the diagnostic trouble codes. Record all codes. Engine Code Example: Source Code: 0 ( Engine ) P(SPN): 27 FMI: 4 27 (4) -- EGR Valve Position Circuit / Voltage Below Normal or Shorted to Low Source NOTE MCI has designated Source Code 0 for the engine codes.

24 Service Bulletin No. 2965C DATE APR. 13, 2009 PAGE 24 DIESEL PARTICULATE FILTER GENERAL DESCRIPTION For 2007 vehicles, the Environmental Protection Agency ( EPA ) requires a 50% reduction in emissions of nitrogen oxides ( NOx ) and a 90% reduction in particulate matter ( PM ). Oxides of nitrogen are created by the high temperature and speed of combustion. Once in the atmosphere, NOx results in ground level ozone formation and smog. Emission particulates include: unburned fuel and lube oil ( liquid hydrocarbons ), carbon soot from incomplete combustion ( main contributor to smoke ), water from combustion and sulfate from the sulfur in the fuel. To comply with these new regulations many changes were made, including: diesel fuel, engine, engine oil and the exhaust system. The new system treats the engine exhaust and is referred to as an aftertreatment system. The main components of the aftertreatment system consist of the turbo pipe, Diesel Oxidation Catalyst ( DOC ), Diesel Particulate Filter ( DPF ), sensors and wiring. The new exhaust system components in general are more complex and larger. A muffler is no longer needed, because the DPF effectively replaces the muffler. The DPF is a porous ceramic filter housed in stainless steel chamber. Flow requirements force the inlet and outlet to be on opposite ends. As the exhaust flows through this filter, emission products are burned and converted to ash. The aftertreatment system monitors the efficiency of the DPF. A self cleaning function ( called regeneration ) is used to keep the DPF functioning properly between regular ash clean---out maintenance intervals, which must be performed by Service Technicians. An optimal DPF size was chosen for low backpressure and to maximize ash storage capacity between periodic cleaning. Regeneration MCI coaches with an EPA 2007 engine are equipped with a DPF system. The ECM monitors engine, after treatment temperature and pressure sensors to determine when a regeneration of the DPF is required. The DPF collects soot and the engine oil in the exhaust system. The regeneration process converts soot into gas, and engine oil into ash. Residual ash from the engine oil remains in the DPF until the DPF is cleaned. Cleaning A Service Technician must perform a procedure to clean the accumulated ash out of the DPF as needed. This will require special tools to flush the ash out of the filter. For heavy--- duty applications the average mileage service interval is estimated to be 150,000 miles. The average time service interval is estimated to be from 1 to 1 1/2 years. The time to perform this cleaning should be approximately equivalent to the time required for an oil change. Removal 1. Position the main battery switch to OFF and block the wheels. 2. Remove four sensors from DPF. 3. Remove sensor module mounting clamp and sensor module. 4. Remove exhaust clamp and exhaust from DPF. 5. Loosen bolt from support brace on outlet module. 6. Loosen band clamp from diesel particulate filter and outlet module. 7. Slide the outlet module towards the rear of the vehicle (approximately 2 inches) to allow the diesel particulate filter to be removed. NOTE: Mark the outlet end of the diesel particulate filter prior to removal for reference during installation. 8. Loosen band clamp from diesel particulate filter and catalyst module. 9. Remove the diesel particulate filter. Installation 1. Position the diesel particulate filter on the catalyst module, making sure that the outlet end of the diesel particulate filter is facing in the right direction. 2. Secure the band clamp at the diesel particulate filter and catalyst module. 3. Slide the outlet module into the diesel particulate filter and secure the band clamp. 4. Tighten the bolt on the outlet module support brace. 5. Install the four sensors, sensor module, and sensor module clamp. 6. Install the exhaust pipe and clamp to the DPF.

26 Service Bulletin No. 2965C DATE APR. 13, 2009 PAGE 26 REGENERATION MCI coaches with an EPA 2007 engine are equipped with three specific tell-tales for the regeneration system: Figure 13. LH tell-tale. 1. Regeneration Tell-tale Lamp ( DPF ). Tell-tale illuminates when a regeneration is required. Tell-tale is OFF during regeneration. Figure 14. Regeneration Tell-tale Lamp 2. High Exhaust Temperature Tell tale Lamp ( HET ). This tell-tale will illuminate when the coach is moving less than 5 mph ( approximately ) and the exhaust outlet temperature exceeds the predetermined level. Figure 15. High Exhaust Temperature Tell tale Lamp 3. Malfunction Indicator Tell tale Lamp ( MIL ) ( on DDC engines ONLY ). This tell-tale indicates a failure of a emission system component on DDC equipped coaches only. Figure 16. Malfunction Indicator Tell tale Lamp (MIL) (DDC ONLY)

27 Service Bulletin No. 2965C DATE APR. 13, 2009 PAGE On MCI coaches there are three regeneration modes: 1. Passive Regen --- Normal engine operation provides sufficient exhaust temperature for regen to occur with no noticeable effects to the driver. 2. Active Regen --- Normal engine operation does not provide sufficient exhaust temperature for passive regent to occur. Regeneration system raises the exhaust temp for regen to occur. 3. Stationary Regen --- Normal operation of the engine will not allow for passive or active regeneration to occur. The operator must initiate a regen with the remote switch located in the curbside, rear side service compartment. The regeneration toggle switch is located in the RH, rear service compartment ( Figure 17 ). Figure 17. Regeneration switch, located in the curbside, rear service compartment To avoid serious personal injury or property damage, ensure that no persons or objects are at, or within two feet of the exhaust outlet at any time during a regeneration. Ensure that exhaust and outlet are clear of any trash, grasses, or other vegetation or debris. Use extreme caution during a stationary regeneration, as exhaust gas tail pipe outlet temperatures can exceed 900 degrees F ( 482 degrees C ). Stationary regererations are to be performed outdoors only. DO NOT leave the coach unattended during a stationary regeneration. DO NOT perform inside a garage or maintenance facility. DO NOT attach an exhaust extraction hose to the exhaust outlet. NOTE If the coach will be idling for an extended period of time or overnight with the DPF tell tale lamp illuminated, a stationary regen is required to avoid unnecessary engine derate or shutdown. 27
