Traction control turns on crazy when turnin left but not right? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

As other guys said it most likely a roblem with the VSC, this gets inputs from 4 wheel sensors and the steering angle input. if any of those are feeding in incorrect values or the steering is not reading zero at centre straight ahead position rearly weird stuff will happen.

if you have had a wheel allignment they can stuff it up if they alter teering zero position and dont reset it.

you can use techstream to check thge steering sensor is showing zero at straight ahead and also check the readout from all four wheel sensors to see they read same value when going straight.

large difference in tyre pressures might also have an effect

Hmm I wonder what the hell that tech did... I'll check my tire pressure as it's been like 2 weeks.

That's probably it

Here's a procedure but it's not specific for FR-s, there has to be a way to do it without a Techstream or going to a dealer

Does it only happen when you're driving alone, or also when you have a passenger? I've noticed I don't get enough weight transfer on left turns when I'm driving alone.

The wording in that thread looks like it came straight out of the FSM. I suspect that if there was a way to do it without Techstream the FR-S manual would also describe the procedure.

the dealer told me it pulls to the left with the VSC because of "radial pull" from the tires...

Sounds like bs. Lol.

Im going to head to another dealer and have them have it done, hopefully I'll have better luck.

After the alignment the car does feel much better. Haven't checked my tire pressure yet and it's 12:41 am (EST). I'm so bored I may head up to wawa now hah

With and without a passenger. It's worse when it's only me though.

Yeah, I can smell the bs all the way over here.

Oh, and -10 points for failure to check tire pressure. Get a gauge and toss that bitch in your glove box ...AFTER you use it!

lol than it's gonna be -20 because I do have one in my glove box...

Nah · 03-03-2017, 02:21 AM

In all seriousness, I assumed the dealer inflated my tires because they did end up rotating my them, lets hope they at-least got that right.
