    HI guys, I'm not new to trucking I've been in it for about 5 years now but don't drive daily. I work for a helicopter firefighting company and im one of their fuel tanker drivers, They sent me to get my license. I'm pretty comfortable driving aside from some regs im not use to but the question I have is about my Truck That's new to our fleet 2013 379 tanker. Its got more bells and whistles than our other trucks and had some questions about some faults that im getting.

    Exiting the freeway I get a HIGH EXHAUST TEMP warning every time.
    And also have a fault coming and going indicating ENGINE TORQUE

    High exhaust temp is be because the truck is doing a rolling regen. This is part of the emissions system. Don’t set your brakes or shut the truck off while it’s still going. Read your owners manual.

    The engine torque is a question mark for me. Could possibly post a picture of the light? It should come on for a brief second when you turn the key on.
