Question about 2001 Chevrolet Cavalier
The no connect fault indicates that you have a ecm issue, however the check engine light will come on if your fluids are low(coolant,oil) if your vehicle was driving fine except for the light coming on chances are there will be no codes and i would check the fluids. Incidently not all code scanners work the same way on all vehicles. On mine which is the kind all major dealerships use you have to have key cards that send a certain signal through the data link. this card is mad for a ceratin kind of vehicle. This could be the reason your friends scanner did not work on the vehicle. keep me posted with the result of the fluid check. I would also check the connection of the oil sending unit and or the coolant temp sensor lead this will cause the light to come on as well. please rate this... thanks
