Engine Light ECU reset?

[Super_Red_Zach]

Hi,

I have had a check engine light come on my 7th Gen Celica. I've spoken to Se7en Motorsport and they're so helpful and said the coolant may need bleeding, I'm sticking my OBD reader in tonight but my question is to get the light off. I've seen a few people remove the ECU fuse to get the light off, will this cause damage to the ECU and how it runs if I did this?

Thanks everyone!

If you have the OBD reader you can clear the engine light that way. I've a bluetooth one and the app lets you clear off the codes once it's read them.

Obviously though, if there is a fault with the car the light will only come on again until the fault has been recitifed.

Or you could just disconnect the Battery for 10 mins, has the same effect as removing the fuse.

I've plugged my OBD in and its MAF needs a clean and then I'll think I'll do that, seems safer  Thanks!
