Have a Nice Day? Noob question. Traction control won't disable 2010 WRX

I'm a new Subaru owner, so bear with me here. I've done a search and read all the info I could find about the traction control and VDCS systems. I've also read the owners manual about how it operates. I'm a little lost on whether or not my car has the ability for me to disable it.

I have the traction control button below my dashboard light dimmer switch and mirror controls on the left side of the steering wheel. This button lights up red, but does absolutely nothing. I can't get the system to actually disable, as in I cannot get the notification light on the dashboard to come on unless I try to play around in an open area and it engages, at which time the dash light flashes. Am I missing something? I would like to play with my car some haha. Does this only allow free wheelspin and VDCS still has control over the rest of the car? Where is the post showing me which fuse to pull for that? (that would only be for temporary bursts of insanity, not daily use)

I appreciate any clarification on this. That's the one part of the car that I can't seem to figure out.

when you push the traction button, it should light up on the dash. it completely disables the system. its not intrusive like other cars. you can do donuts, launch and roast the tires,whatever. it will stay off until you shut off the car.

that's my problem, I cannot get the light on the dash to come on by pressing the button. I read the user's manual on how it works and I'm doing exactly what it says to do and it will not come on. it does have a tune on it from my Cobb AccessPORT and I don't know if that affected It at all

Do you see the TCS light when the car turns on? Perhaps the bulb is out? Very rare on a 4 year old car but it doesn't hurt to check.

Yep, no problems with the TCS light. It blinks at me when the traction control system engages which is what I don't understand.

So if you start slipping to engage traction control, see the TCS light, hit the TCS button, and then try to trigger the TCS, will it engage?

There are two different icons for VDC. When you slip the swerve icon lights up in the tachometer. You are trying to disable the VDC. With the car running press the VDC button by your left knee and you will see a yellow "no swerve" light by the engine temp gauge. Now go have fun.

You need this on by the temp gauge.

Okay, I don't have that light come on at all. Not even when I first start the car. Now I'm thinking I don't have VDC because I just did some pretty sweet drifts and the swerve icon lit up, but I didn't see any VDC lights. Do any models of the 2010 WRX come without it by any chance?

No it's required by law. So you press the button for a second (don't hold it) and NOTHING on the dash lights up? Time for the dealership.

That swerve icon with the line going through it (pictured above in snow drift's post) doesn't even light up when I first start my car. I bought it used and the warranty is definitely gone with all the mods done to it and with 40kMi. Forged JE pistons, New rod bearings, timing belt, lightweight main pulley, exedy stage 1 clutch, Cobb equal length headers, Invidia up pipe, down pipe, and cat back, HKS bov, Perrin intercooler, hoses, coolant reservoir, Cobb short shifter, Sek-Tor forged wheels, and came with a Cobb accessport with a stage 2 tune installed. I think I'm forgetting some things too. It's a sweet ride, my turbo pressure gauge isn't always accurate but normally displays about 17psi max with the stock turbo (unsure of it's accuracy). My accessport said I'm making 300bhp in the pull test. I think it may need a custom tune, but idk for sure. It definitely runs great.

Anyway, does this sound like it could have been mistakenly/purposefully done with all of that work done? Does it have something to do with the tune? Is it common for that to be removed? The previous owner didn't even bother to keep the TPMS sensors and put them in the new wheels (they fit too), but idk enough about my WRX yet to know better.

Thanks for all of your help everyone!

If I remember correctly, VDC cannot be disengaged or turned off on WRX. only STI has that ability.

afaik, tcs is enabled by default and disabled by pressing the button, as mentionned above. Vice verca, there are easy ways to have it disabled by default also. Could the previous owner have had it disabled by default? Can you ask him/her?
The tune should not be impacting that function (I've never heard of it at least).

My car is telling me to drive like an idiot, because it is at all times disabled. Is there a thread on how to disable the WRX traction control? Maybe that way I could figure out how to enable it. Could that be part of the tune it has? The dash light has never lit up for me, not even when I start the car. This is what baffles me.

I'm not totally clueless about cars. I'm Kawasaki and BMW certified as a motorcycle technician, but that says nothing about Subaru's and traction control haha.
Am I totally screwed with having to take it to the stealership? Thanks again everyone

Yeah, I'd say you're screwed. Unless you can get Helen Keller and Ray Charles to work on your car.

Edit: 300hp seems VERY low. People say the Cobb accessport typically aims ~25% high. Not that I'm saying you can use the Accessport as a dyno but I think it's intended to use when comparing 1 map to another.

So you think I have more than 300? I know the accessport isn't accurate like a dyno, but it was only a second gear pull. I didn't want any tickets haha

Ehh I'm really not sure. I'm just saying the Cobb is usually at least 25% higher than what you are. They seem to be consistently inaccurate. So if it's reading 300hp maybe that is your "high reading".

Either way. I can't stress enough that the AccessPort dyno ("Dynameter" or something) is very inaccurate. It shouldn't even be used to tell how much HP your car has. The way it's used is if you get 300hp on the Dynameter and then do a new tune and get 350hp you can look at it and say "My HP increased". NOT "I gained 50hp!".

Maybe try reflashing your tune? Go to Cobb's website, read the map notes for your year/model, and flash the appropriate map. I would also be careful because I feel like your mod list may require a protune, not the generic Cobb Stage 2 map.

Thank you very much, researching the current map and specifics will be my next step.

I ended up needing an Air Oil Separator, purchased from Perrin. Excess crankcase pressure blew the gasket between my intercooler hose and top of the turbo. Also causing a risk of detonation. Getting at least a street tune next week. I've been running the Cobb Stage 2 ACN generic tune because the non ACN tune kept giving variable A/F ratios. Playing it safe for now until I get at least a street tune. Thanks for your help guys. AOS going in tomorrow as well as a new gasket for the oil leak. Will post updates after the tune, seems like my bottom end doesn't pull anywhere near as hard as it should. Constantly relying on the turbo for power

Please tell me I didn't buy my AOS for no reason haha. It says it restricts the pressure going into the intercooler for the same effect, but I'm not sure. This is what I ordered...

Actually, I checked and I already have that same exact part in Red haha. Matches all my other Perrin parts. I have Perrin everything. Also, that COBB Stage 2 tune was adjusted by and sent to me by Perrin themselves just for my setup. Still going to try a street tune though

As far as your TCS/VDC issue, what some XV crosstrek / Impreza 2.0i people have done is pull the ABS fuse and hold the brake down for a few seconds when they first start the car. The dash lights up like a Christmas tree, but the TCS, VDC and ABS are all disabled, which lets you have as much fun as you want with no interference from the car. Use this method at your own risk though!

Actually, it's permanently disabled on my car. I don't need to pull any fuses, I'm pretty sure it was disabled electronically. I should be able to bring it to the dealership and have them turn it back on with their computers

Hmmm, you have all these upgrades and no good way to really put it down with that peg leg diff and now your TC is disabled which really limits your ability to use the car to its fullest. As you add power, you will start having traction issues. The WRX doesn't have a limited slip in the rear which put more emphasis on TC to keep your car going in the right direction. If you do not want to re enable TC, I would start considering upgrading the rear pumpkin. You are really missing out.
