Service Traction Control system light...

[06MidnightBlue]

So yea...it's been going on and off the post couple days. It will shut off and stay off for a while when u turn the car off and on again. What all could be giving me this headache? I wanted to ask u guys before it goes to the dealer

Thanx!!

Couldn't tell you, but I can relate. It used to only happen when it was cold out, but now it happens a good bit of the time. It could just be that I beat the hell out of it on the trails, but I can't see how that would affect it too much.

[janesy86]

Mine has done it for a while now. From reading lots of posts on trailboy, it seems as if its the clockspring. Thats if I remember it correctly.

[navigator]

or is it the steering wheel speed sensor?
Mine doesn't do it enough to worry me.

[janesy86]

Yes, I believe your right Chris. I couldn't think of that off the top of my head. Pretty sure thats what I remember.

[HARDTRAILZ]

Mine did it on and off for awhile. But I don't think it has happened lately. speed sensor does sound right.

What kind of spark plugs are you using?

What kind of spark plugs are you using?

What possible connection can spark plugs have to a Traction Control light?

this made me laugh until I started coughing ( a cold I am trying to beat).

BWAHAHAHA.

Ya it sounds funny but the same thing was happening to me flashing like that, then it was just on all the time. I was using bosch platinum 4 spark plugs, as soon as I switched to ac delco irridium the light went away. Maybe if he has a diffrent plug he can try that too.
This is for laughing

[hobbstisdaman]

Sounds like a fishy coincidence to me!

[djthumper]

at this point that is his story and if I were him I would stick with it...

[06MidnightBlue]

So I went to work today and pulled the code, C0244. Now this is what puzzles me...

I did some research online and found that those who also pulled this code in their trailblazers said it had to do with the Steering Wheel Position Sensor. Now maybe I'm just having a brain fart day, but can someone NICELY explain to me how the position of the steering wheel has anything to do with the traction control system?

IIRC it has to do with aiding in the control of a slide if you are going around a corner or going sideways.

Oooops f'd up on this one. This light went away with the steering wheel position sensor. My bad it was the stabilitrack light that went away with the plugs...dont know how that happend but it happend. And Next time ill pay a little more attention before I write, My fault.

[janesy86]

Same thing.

[Infamouz]

I thought so, but with alot things being named different things its hard to catch up. Ive always known it as stabilitrack. So how is it that it went away after changing the plugs? No one answered me on gmtnation ether.

I asked here post 8..http://gmtnation.com/f23/service-stabil ... /#post9489

Told people here how it went away only one guy said maybe it was from plugs post 20..http://gmtnation.com/f25/supersparkz-578/#post20784

I've stayed out of that thread because those copper tubes are crapola. Snake oil. Rationalized by lame physics and a total lack of ethical treatment of the enthusiast community. The guy doesn't even have the respect and process control to cut the tubes to a consistent length.

A wire spring is NOT a worse conductor of the spark energy. I'm designing a transistor tester right now that's switching at least 1000 times as much energy (80KW) in 1000 times shorter pulses than the spark plug (nanoseconds instead of microseconds.) Remember resistor plugs and resistor plug wires, that served to slow down the plug pulse to reduce AM radio interference? 10KOhm resistance didn't destroy the spark totally, although those spark waveforms probably wouldn't work well in today's cylinder environment. The inductance of the springs may even have been considered by the designer, and are an integral part of their rising edge pulse shaping, and possibly the falling edge quenching of the spark.

But I'm the new kinder and gentler Roadie over there and I'm not going to ALWAYS protect people against wasting their money. It ruins the placebo effect.

Changing from Bosch to Delco plugs AND adding those pipes at the same time is a NUTTY and non-scientific experiment. Changing only ONE thing at a time is the only valid test. The only connection to the Stabilitrac system is that installing the plugs and pipes can jostle the harnesses inder the hood, and if there was some intermittent wiring, the plug activity might have accidentally fixed it.

The steering wheel sensor often goes intermittent because it's almost always sitting in the straight ahead position, and it's a potentiometer. The non-rotating part wears out in the place where the moving part spends most of its time.
