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 intervals. Failure to maintain proper diesel exhaust fluid levels or if the diesel exhaust fluid becomes contaminated will result in vehicle speed limitations or result in your vehicle entering an idle-only mode. See Selective Catalytic Reduction System (page 20). 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 exhaust gases and a secondary cooling loop to cool the transmission, exhaust gases, 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 General Maintenance Information (page 58). . Operating the engine with insufficient coolant or coolant additive can cause severe engine damage 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 that you must replenish at certain Minor Troubleshooting Guide If the engine won't crank WARNING Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling. Turn on the headlights. If the lights are dim, do not go on at all or when the ignition is turned to START the lights become dim or go out, the battery connections may be loose or corroded, or the battery may be discharged. If there is a clicking or stuttering sound coming from the engine compartment when you turn the key to START, this may also indicate a loose or corroded battery connection. Check the battery connections at the battery posts, cable connection to the engine grounding point and at the starter connection. If you suspect a discharged battery, have it checked and corrected. 5 Super Duty (TFA)
