Icon10 SO EXCITED! 4th Gen 4WS issues? READ THIS!!

So... after about 10 years of being completely *#$^ing annoyed because I have to stare at my 4WS light almost every single time I go anywhere, I have finally fixed the problem without spending $2,500 for a new 4WS Control Unit from Honda.

The problem was that I had code 62(it's always been this code), which in the HELM manual is attributed to the electronic control unit/power unit/rear steering actuator. It was most definitely only the control module.

I followed this tutorial from honda-tech.com:
4ws error codes - What next?? - Honda-Tech

This is what the inside of the control unit looks like:



The problem is underneath the circuit board that is connected to the control unit case. I'm sorry that I didn't get a picture from underneath, I wasn't thinking about it. The issue is the 10 solder points for the two relays that turn the unit on when you start the car.

Even though the solder points didn't look like they'd failed, I followed the recommendation in the tutorial and added more solder to all of them, then let them cool off because the relays get really hot. You might hear some cracking; That worried me a little, but it didn't seem to be a problem. The clear stuff on the back of the board melts some when it heats up.

After that I reassembled the control unit and put it back in the car. If you're having issues getting all the 10mm bolts back in, make sure you take your time and get it right because the bolts provide the connection to body-ground that allows the control unit to function. After that put your seats back together, then remove the clock/radio, ABS 2, and small lights fuses for about 10-15 seconds. This will reset all of the computers in the car. Now you can start it, and see that your 4WS light is off. You can cycle the ignition a few times to see that it's worked - it's pretty exciting once you're sure it's done.
