2004 Silverado check engine light is on when you hook up scanner multiple errors or problems ? Truck runs fine shows dash cluster is bad , engine preheat air is bad etc etc ?
Every thing in truck runs fine. Duramax diesel, code scanner shows many
errors but every thing works fine ?? It shows dash cluster bad , engine
preheat air relay bad, class 2 data link malfunction.. loss of communications
to engine control system , rear wheel speed sensor malfunction, glow plugs
bad ?? and a couple other items, Gees the truck runs fine so why is it saying
truck is needing total over haul ??? any ideas ????
Those silverados are really sweet rides but when that check engine light comes on you better have it checked by a shop w/ all the right stuff; sorry, but those lights don't come on for frivolous reasons and did you know a used car dealer will not buy any vehicle that displays a check engine light? This can result from lack of regular maintenance checkups that would replace oil at so many miles, etc. very important to do; u gonna need a pro, sorry and best results for you
That is what is weird I have this truck serviced like clock work if there is an issue of any kind I have it fixed asap. But to have it think the truck fell of a scrap truck ?? Am betting the Processor or PC has taken a crap.... But want it fixed .............
