Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
Hi, My name is ***** ***** I'm here to help you,
What manufacturer is the truck?
When the stop engine light is on it means the coolant is low or there is no oil pressure. The cruise control not working because either the micro switches are not working on the brake/clutch pedals or the vehicle speed sensor is not talking to ecu, or there is a wiring problem. i hope this answers your questions.
Please rate my help from today,
Thank you, Doug.
