2004 Saturn Vue exclamation point light

First of all make sure all the tires are the correct size as stock.I had one once there was a mismatched tire.Also your going to have to have a professional scan tool scan your car for codes.Then let me know the exact code numbers not code descriptions? You may even need that scan tool to fix it.You can get older scan tools on ebay that would scan all the computers on your vue pretty reasonable.

I had this at mechanics he did scan for codes but nothing came up he's stumped also..don't know what to do

There should be codes what kind of scan tool did he use?Not all scan tools will read all the computers in your vue. Also did you check your tire sizes?

2front tires are 1 kind and 2 back tires another brand but all same size. Idk scan tool wasn't there

As long as the tire sizes are the same that wont cause a problem the lights shouldn't come on unless your loosing traction.The first thing I would do is do a full scan on all your computers and see what codes you have.

I went to autozone had them read codes this is the only one that came up...u0121..plz help

That's a code for the can network for the electronic brake traction control module the auto zone can only read engine transmission and the u codes.They cant read the codes for traction control brakes etc . Without those codes you dont have a starting point.Like I said before the first thing I would do is a full scan of all your computers in your vue.Iam a factory trained saturn vue tech and thats where I would begin in diagnosing the problem.

Ok ty I will tell my dad..

You might also need that scan tool to diagnose the problem to view live data.

He wanted me ask u when exclamation comes on is ut normal to govern the engine down?

If the computer sees or thinks one or more wheels is traveling a different speed it will retard timing etc to try to correct what the computer sees as a low traction condition. Have you checked to make sure all the tire pressures are correct?

Will check that but checked other day and all at specified..taking to gm dealer Tuesday will keep u informed. .ty

Your welcome keep me posted.

Here are the codes...c0035...c0245...c0271 I think cant read this guys writing too well...and b2400..estimate was 2013.97...cant afford this for a 3000 car...but what are these codes?

C0035 is left front wheel speed sensor circuit malfunction. The c0245 is wheel speed sensor frequency error.the c0271 sounds familiar didnt see it on my online repair info the b2400 doesnt ring a bell and cant find that one ethier.Can you scan the paperwork they gave you and post it on here so I can read it?
