ABS and Slip Light - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

illxkoncept · 06-27-2017, 01:35 PM

My ABS and Slip Light are constantly on. I tried shutting the car off and turning it back on and they're still on. I'm planning to bring it to the dealership. Only problem is I'm on an oft tune. I currently have the stage 2 uel 91 tune. Should I flash back to stock before bringing it in? Since I have catless headers won't that throw a code?

Use your OFT or another OBD scanner to see if the car can tell you what's wrong.

If you've messed with the wheels/brakes at all you might have a damaged wheel speed sensor which would cause those lights to come on.

See if your brake lights work. My friend had the same issue and it was a broken brake light switch under the pedal.

Is there a CEL as well as those lights?

My money is on a wheel sensor then. Although even that could throw a CEL.

Oh forgot to answer the question! Some dealers may be fine with the tune but I would flash back just in case. Should take a bit before the header throws the code if it does at all.

Is there anyway I could know which one? I tried looking for a fault code with the oft and it came up with nothing

I also just noticed my alignment is slightly off. Could that cause these lights to come on?

idk if it throws a code for the header I'd bet money the dealer says they can't fix it because of the header code and don't do anything for him... but that's just my pessimism.

So you think it would be better just to leave the tune on so it doesn't throw a code for the header?

I would swap back to stock tune and header... after inspecting all the fuses, wheel speed sensors, and alignment.
I have no idea what would be best in your situation.

I've had those 2 come on for 2 things!

1. My alignment was off (visibly off) and those 2 were on.

2. I had a blown brake fuse, see if your brake lights work! If they don't, replace fuse and ur good.

Tell us more about your alignment being off. Is it really screwy? If you have a ton of toe out in the rear it might be enough to constantly be tripping the light.

I'm in the boat that you likely have a damaged sensor, but it's totally possible that an alignment that's really bad could do this.

Did you do LCA's without toe arms perhaps?
