Need help figuring something out - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Soooooooooooooo for some reason my abs light and my traction control light come on after a bit of driving but not when i immediately start the car. it could be a speed sensor(on my guess) but could it be something else? the car doesnt drive any differently or anything but id rather not have lights on my dash. it also prevents me from using my cruise control or sport mode.
Thanks in advance everyone!

Do you have any mechanical mods such as a header or maybe an intake? Larger diameter wheels in the back than front?

Do you have a way to get an OBDII scan done?*

Do you have a check engine light? (It appears not).

*most likely will tell you the cause, maybe a sensor or something.

And lastly, if you are within warranty, just take it to the dealer.
You might have an issue with a sensor, possibly ABS/wheel speed sensor.

I had issues with my tune not cancelling the check engine light for one cat removed. Also, had a dirty MAF sensor. When the CL light went on, so did the traction light (but not ABS) and also cruise would not operate.

I'm about to make what is going to seem, on the surface, the stupidest post of the day, and possibly of this forum's existence:

Check your brake fluid level.

Actually, I think that's a very good suggestion.

Sounds like "limp mode" to me. There is usually a CEL involved as well but not always. If it is then it could be jus about anything.

As asked, any mods? Intake, header, anything?

You're right. Let's try this again.

Rent a hanger. Disassemble your car completely - the scene should look like a Mayday NTSB crash investigation. Analyze the flight data and voice recorders for clues. Reassemble your car. Check brake fluid.

actually its full cause i was wondering about it.
i think it could be a speed sensor though since its delayed though. and no mods totally stock to those asking.

No. And the lights only come on after driving a bit. it comes on sooner the faster I drive( like on a highway compared to driving on backroads.
