Hey man,
I went to the Honda dealer and they said that the rear angle sensor recall was already performed on my car. I tried everything to fix my 4WS issue.
Then, about a month ago, someone posted the re-sodering of all 10 connections on the two relays on the 4WS ECU. As soon as I resodered all 10 points...my 4WS has worked perfectly fine.
I was getting an error 62.
Did you go to the dealer to see if they performed the recall on your car??
