Happy warning light for nothing. Hate those kind of fault warnings. Our fleet of Kenworth trucks have all the new automated devices like adaptive cruise, lane departure warning and auto braking when to close. These devices throw fault lights/codes and dialog boxes pop up on the dash screen screaming oh my God type warnings when nothing is wrong. The systems fail and the components stop working ...... and then they just come back on. Sometimes to get the systems to work again we have to stop for 10 minutes to reset the computers by turning off all electrics including lights and unplug accessories in cab like satellite radio so all electrical draw is off.
They think they are going to have self driving trucks one day. Not going to work with this level of quality of the electrical gear installed.
