check transmission left-turn signal transmission temperature high-beam headlights service transmission daytime running lights right-turn signal wheel spin unfastened seat belt low air pressure intake heater wait to start (EPA10 and newer vehicles) water in fuel high exhaust system temperature (HEST) fuel filter restriction diesel particulate filter (DPF) status optimized idle malfunction indicator lamp (MIL) power takeoff (PTO) engaged CHECK engine Common Lightbar Lamps Indicates a critical engine condition (low oil pressure, low coolant level, high coolant temperature, high DPF soot level, or uncontrolled DPF regeneration). Correct the condition as soon as possible.
If the condition worsens, the STOP engine lamp will illuminate. CHECK Engine Indicates a serious fault which requires engine shutdown immediately. The engine protection system will reduce the maximum engine torque and speed, and, if the condition does not improve, will shut down the engine within 30 to 60 seconds. STOP Engine The driver must safely bring the vehicle to a stop on the side of the road and shut down the engine as soon as the red light is seen. If the engine shuts down while the vehicle is in a hazardous location, restart the engine after turning the key to the OFF position for a few seconds. Move the vehicle to a safer location.
Slow (10-second) flashing indicates a regeneration (regen) is in progress. High Exhaust System Temperature (HEST) Solid illumination indicates high exhaust temperatures at the outlet of the tail pipe, when speed is below 5 mph (8 km/h). It does not signify the need for service; it only alerts the vehicle operator to high exhaust temperatures when a regen is in progress. 3.1
