Traction Control Kicks On Around Corner
 

2013 FR-S. When cornering to the right, the traction control will kick on and car will act strange. Does not do that when turning to the left. Any ideas?

you mean to the left?

How are your tires?

Wrong place for the thread. This needs to me moved to the Suspension | Chassis | Brakes section in Technical Topics.

Same thing. Oversteer only on right turns, fine on left.

Michelin supersport tires 225/45/17.

The trac off button doesn't fully turn off the TC you need to do the pedal dance to fully turn it off.

I'm assuming it's with the TC still on?

A few possibilities come to my mind.
- driver weight on one side? (This may be invalid if this is already accounted for when setting the car up from the factory)
- alignment differences from L/R?
- If it's not the same place, maybe the road surface is different?

Tires are in excellent condition.

If the tires are a different height width or you have different wheels from stock sizes you need to do a Zero Point Calibration.

As noted, it could well be just driver weight. Turning right, you are adding more load to the left side (including driver weight), and lightening the right side. Turning left, you are reducing load on driver side and adding to (lighter) passenger side. I can tell the difference when I track my car with, and without, my son riding along (about same size).
If you have some spot that is repeatable, try it with, and without, a similar-sized friend riding shotgun.:thumbsup:

Is this test being performed on a skidpad?

On a public road what are the odds you're actually performing exactly the same turn right vs. left? I'd say pretty slim unless you're in a parking lot.

I did google it, cant find anything. Can you explain the process? I assume ill need some type of interface into ODB2?

Thanks!

See if you can get a big empty parking lot with consistent, fairly fresh asphalt and try both left and right hand turns. Bring a passenger along to see if it's truly repeatable. Snap the wheel 1/8 turn each time, then 1/4 turn and see if both times it was identical.

I think the previous posters are onto something with either inconsistent turns, passenger weight, or a super screwy alignment.

Have you had the car aligned? Has it always done this or is this new behavior? (Or is the car new to you?)

^ +1 on alignment if there truly is a problem
