ACCORD Gen 7 2.4 aut
Hiya. I have one of the last gen 7, 2.4 estates on a 58 plate with all the bells and whistles. The orange LKAS/ ACC light is keep coming on, the only thing that has changed is that I have had a new tyre fitted to the rear passenger side. The other side has a tread with about 4mm on it. Looking at other posts I notice tyre pressures imbalance can cause problems could a difference on circumference also cause a problem and is a new tyre for the other side the only way forward Apologies for the lengthy post..
 
I don’t think such a small difference in rolling radius should cause this. Are you able to have the car scanned with a Honda system to check what error code is presenting?
 
Thanks for the reply. Forgot to mention only happens after speed is above @ 45mph and resets after car is restarted. Got a basic ELM327 Obd scanner no codes picked up
 
You won’t be able to interrogate the system with a basic code reader
