I have a 2019 Corolla with 22000 miles, with no trouble lights showing.
I tried replacing my horn with a louder one and it blew a fuse. So I reinstalled the original horn and replaced the fuse. Now the lane departure warning system does not work. How do I fix it. {black}:idontknow:
Oh dear, did you check all the other fuses?
Anyway, since everything is back to stock, take it back to the dealer & let it become their headache.
Obviously, don’t tell them about your little escapade..
I did check all of the other fuses.
{black}:serious:
Then let the dealer deal with it. Were any wires cut during the aftermarket horn instal? I hope not.
you really need a computer to tell you when you're drifting out of your lane?
you can't figure that out yourself?
Try to reset the system by disconnecting the negative battery cable put it back after 30 min. If it didn't solve the issue, you may need a dealer level scan tool to fix it.
