The 4ws doesnt always turn on when I start my lude. When the engin is cold it works but when the engin is hot it doesnt always turn on. I also noticed that when i drive with the 4ws light on for several minutes then shutting the car off and starting it right up again the 4ws works fine. Could this be a problem with the 4ws module?

 

What year is your car? The 4WS on my '88 is mechanical - there's really no way for it to "not work" aside from some mechanical failure. I can't speak for other generation preludes, since this is the first (and last) Honda I'll ever have, but that's what I know.

 

You might need to resolder the relays in the 4ws control unit. I was having the same problem and that took care of it.

thanks sean, ill give that a try. Ill let you know how it turns out.

 

I took apart the 4ws unit today. sure enough 2 of the relay connections were really bad. I resoldered all the relay connections and its working without any problems. thanks alot sean, and thanks to whoever posted the pics step by step, it helped out alot.

 

No problem, glad you got it working!

That 4ws ecu is a pita to get out though...

 

yeah it was a pain in the ass to get out but now that it works like it should, it was all worth it.

 

Have you done the swap? H22 and 4ws together rock!

 

no, I havent done that. still on the H23. ill look into swapping for the H22. but I dont know when thats gonna happen.
