Stabilitrak light blinking NO Acceleration

[BG1988]

Thanks man. I will check that out and see if mine has a button there I don't recall seeing anything but I was not looking either.........

yes there is a button to turn it off standard equipment

That just resets the light if there is a malfunction and it wont turn off. The stabilitrak "relearns" every time the vehicle is started- it does a diagnostic at that time.

Awh OK so if you push the button and hold it for about 5 seconds it turns the stabiltrak system completely off. Only thing is it turns on the yellow dash light. With it off though I can drift pretty effectively, I like it, great tip thanks. might look into teh actual tech2 thing later it does not bother me too much I will just turn it off when if I wish to drift.

if you pull some fuses you can do burn outs as well.

YES-....I have an 08 hybrid...large tire wheel combo...28 x 10-295/25/28...and this has happened several times to me as well....steep on ramps...sharp turns...engine shuts down...im thinking it has something to do with the tire wheel combinations were running in regards to angle/deflection and the stability track system...your thoughts??

09 Tahoe Hybrid 204k miles. I have had a blinking stabilitrak light on hard turns at speed and when going slow since I bought the truck several months back. I have driven it about 8000 miles. I thought it had stopped after the last front wheel hub bearing replacement was done but it still does it. The light comes on and blinks on hard turns mainly on right turns. This really gets to be a problem on a Interstate On Ramp that has a tight right turn, if the light is blinking the engine will NOT accelerate until the light stops blinking this could take 2 to 3 seconds and that creates a dangerous situation trying to merge int traffic. Obviously I can slow down to an almost crawl around the turn and the light stays off but I think it is time to look at this closer and figure out what is really going on. Has anyone here experienced this particular issue before? I am seeing 3 main components in the GM system. Yaw Control sensor / Steering wheel angle sensor /accelerometer. Both front wheel hub bearings have been replaced since I have owned it so I think that eliminates a wheel speed sensor issue? Now this Hybrid is lifted 3.5" and has oversize wheels 20x10 and oversize tires 285/55R20 so of course that could contribute to the issue. Just wondering if anyone in either stock configuration or lifted has noticed the issue? There is some data online about the blinking stabilitrak light is a normal condition but does not mention that it stops the engine from accelerating when it is blinking! I really do not care if it blinks once in a while but I need all 385 horses on line when merging! NO CODES are stored.......

Yes I agree it is most likely the lift and wheel tire combination. Not a major issue, more of an aggravation.

strange issue...it seems to be happening more and more with my hybrid....least I don't panic anymore and relieved when the motor kicks back in!

I would take a look at the ground wires as well since GM just chain linked Bare braided aluminum wire from the body to the engine then insulated Copper to the battery this could add some resistance Ω


. esp for salty areas were things get rusty and corrosion etc..

thanks- plan on looking at it this weekend when im changing plugs and wires.
I'll post if I find the ground wire to be the cause.

it's not just that the engine block becomes a electrical resistor it self as the engine block warmed to 105C(maybe even slightly more ) will have more resistance then at 20C..


Yes the mass is BIG but still has some extra resistance

Basically they cut the corner not running a dedicated Copper Cable to the chassis from the battery...

I plan to do the big 1 upgrade on this
Battery to chassis with #2 or #0 copper wire gauge.. )



basically the 6 or 5 AWG braided aluminium cable is the weakest link in the chain...



in order to keep electricity happy you have to give it the path of lest resistance ( but electricity will get mad if it's shorted )

Also i would clean up the battery if it's old as the plastic housing can be come conductive over time (like a resistor)...
