Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.

Expert:  Dan replied 1 year ago.

That is a warning indicator to the driver that there is a fault in the power train control system and the vehicle has gone into limp home operation or a problem with the transmission has been detected and the shifting may be restricted, you need to contact you local dealer and have the power train system looked at and diagnosed to see what system the problem is in and have it corrected, depending on the problem the check engine light may come on and the system will display pull over safely in the message center and the truck will shut down, hope this helps.

That light comes on when the power train control module sees a sensor or component that is out of the set range that is programed into the module, the PCM is continuously monitoring the sensors on the engine, exhaust and the transmission and if it sees a sensor out of range for 1 drive cycle it will turn on the wrench light, if it sees it for 3 drive cycles it will turn on the check engine light.
