Sup guys, for some reason my 4WS dash light comes on every now and then. Any ideas why it could be comiing on?? Any ideas how to troubleshoot???
Before....when I go the car..the light came on....I checked the tire pressure and they were all wrong. I filled them all up to the correct specs and the light went away.
Recently, I was trying to replace my rear speakers....and I noticed that there seems to be a problem with the wiring to the rear speaker above the 4WS ECU. The original speaker kept fading in and out..so i tried a new speaker. The new speaker hardly plays. I have to CRANK up the volume all the way just get a decent volume out of the speaker.
I want to try the other speaker on that speaker connections to see for sure if there is something wrong with the wiring..but for now I was wondering if you have any ideas what could be causing the warning light to come on.
Thanks

 

Yeh I have that problem too. It seemed to occur after I installed a system in my car, any suggestions??

 

You can find out the same way you check the code on the check engine light
http://www.hondaprelude.to/main_checkengine.html
That is for the 5th gen. it is done the same way just the plug is located behind the center console. I know in mine it is a blue plug some it is yellow. It will be a plug that isn't plugged into anything and has a weird cap on it. When you check the code the 4WS light will blink just like the check engine light would. long blink=10 short=1 so 7long blinks and one short would mean a code of 71. I just had this explained to me today and did it. It is easy.
Here are the codes

70 - The ignition is turned from off to on while driving - 4WS light would come on for this one.

71 - The car is driven aggressively with the driver and three passengers on board, or the steering wheel is turned with a rear wheel blocked by the curb, etc. - no 4WS light on this one

73 - The engine is started while quick-charging the battery - no 4WS light on this one

74 - Driving the car with the parking brake on - 4WS light after 5mins after detection

After you check this make sure to reset the ECU by removing the radio fuse for at least 10 secs. If you get a code that I didn't list then you should take the car to a dealer and ask them what the code could mean.

 

Have you Considered the fact that A speaker has a Magnet, and that also has electro magnetic signals passing through the speaker. I would try first re routing the speaker wires, and if that doesnt work Dont use a speaker in that location. I would imagine that it only does it with the stereo on.

Im no Expert on Honda 4ws, but I have owned a Car Stereo shop, and worked for 3 others. All my real systems are a simple layout, 5 speakers Max. 3 works just fine. 2 are the front pair of 2 or 3 way speakers, and one good sub.

I might also consider moving the 4ws box Im sure it can be unmounted.

I have a 4ws Prelude but its going to the crusher once the engine is out, and any valuable parts.
