Hi,my 07 6.2 denali drive me crazy on daily basis i am getting traction conrtol message ,abs ,and stabilitrak when i turn the engine off and restart again it all goes sometimes check engine remains but with 2 to 3 starts it gose ,i took the car to the dealer many times and everytime they told me they found nothing today they told me that i should change the pcm but i am out of warently my car is running up to date 95000 miles so i will pay the bill the car has stock tuning any help on this or has any body faces this before ?

 

Get a custom tune either by mail order or local.

 

The dealer has installed the latest version of the stock tuning ,after i post this topic i did some searches and i found that if the wheel speed sensor is not working will it may cause this problem so dose this sensor have any relation with this?

 

yes it has everything to do with it. the speed sensor is how the ecm opperates tcs antilock brakes and so forth.

 

have you had anything on the truck serviced lately?when did the lights start coming on?you need to have the ecm read for trouble codes,it will help pinpoint what the prob is.

 

since a couple of months i have this thing ,i dont remember if i did something that causes this problem tommorow i will take the car to the dealer and i will tell him to check the wheels sensors.
