Introduction The powertrain and glow plug control modules electronically control the glow plug system. After you switch the ignition on the glow plug control module immediately energizes the glow plugs. The glow plug control module using the engine coolant temperature, barometric pressure sensor and environmental temperature sensor will determine how long the glow plugs stay energized. The required time for the glow plugs to be energized decreases as the coolant temperature, barometric pressure and environmental temperature increase. Glow Plug properly. Regeneration of the diesel particulate filter occurs automatically during operation above 30 mph (48 km/h) and requires no actions from the driver. If you do a lot of idling or stop and go driving, pay attention to maintenance messages that alert you when you need to drive to clean the diesel particulate filter, or perform operator commanded regeneration. See Emission Control System (page 30). Selective catalytic reduction system Your vehicle is equipped with a selective catalytic reduction system designed to reduce emission levels of nitrogen oxides from the exhaust of your diesel engine. This system relies on the use of Diesel Exhaust Fluid (DEF) that you must replenish at certain intervals. Failure to maintain proper DEF levels or if the DEF becomes contaminated will result in vehicle speed limitations or result in your vehicle entering an idle-only mode. See Selective Catalytic Reduction System (page 21). Speed control If your vehicle speed goes outside a predetermined range from the set speed, the RSM (Resume) function will not reset your vehicle speed. You will need to reset your vehicle speed with the SET+ or SETbutton after reaching the desired speed using the accelerator pedal. Engine and secondary cooling system The cooling system contains a primary cooling loop to cool the engine and a secondary cooling loop to cool the transmission, charge air, and fuel. The coolant serves three primary purposes: to provide heat transfer, freeze point protection, and corrosion protection using additives. Vehicles with diesel engines typically are used to carry heavy loads and accumulate mileage rapidly. These two factors may cause the additives in the coolant to wear out in a shorter time. For more information about coolant additives and coolant change intervals See Engine Coolant Check (page 45). . Operating the engine with insufficient coolant or coolant additive can cause severe engine damage Diesel Particulate Filter system Your vehicle is equipped with a diesel particulate filter in the exhaust system. The diesel particulate filter reduces carbon emissions by trapping exhaust particulates (soot) before they reach the tailpipe. You must properly maintain your diesel particulate filter in order for it to function Minor Troubleshooting Guide If the engine won't crank WARNING Battery posts, terminals and related accessories contain lead and lead compounds.
