Default 4ws steer preludes... lots of codes are thrown, does moving the computer mess it up?

i have a 92 si 4ws. i moved my 4ws computer in the trunk, layed it down flat and mounted it so i could put in a rear upper sway bar, i dont rememeber if the light was on before i moved it but it def is now. im not even sure if the 4ws is even working and am about to just junk all of it to lose weight. i might try remounting it in the original location but the whole system is so complicated and there isnt much information online to be found out about it. the light blinks reallly fast and its hard to read the codes. any 4ws techs please help.

If all you did was relocate it without extending wires, there shouldn't be a problem at all. The unit might be grounded on the chassis, so I would check that the mounting bolts have continuity w/ground.

Once you have grounded it properly to the chassis, here is a write up on how to reset it & cancel the light to get it working again.

.................................................. .................................................. ...................

As you know you drive in passenger seat!!!! for us so the location of the service connector could be on the opposite side.
It is located right side of the centre tunnel under the dashboard, when you look at it there is a removable carpeted cover where the centre tunnel ends under the dashboard.
After removing it you'll see 2 connectors plugged in a cover (they should be blue if I remember correcty). The small one which has 2 pins in it is the service connector, and you need to short these pins.
So if you can find it this is how it goes:
1. Apply the hand breake
2. Short the service connector pins with a paper clip or something
3. Turn the steering wheel to CLOCKWISE (right) 45-65 degrees and hold it that way
4. Turn the ignition switch to II(on) position but DON'T start your engine
You'll see that all your warning lights (SRS, ABS..will go on and off, don't pay attention on them),
5. After your 4WS light goes OFF, turn the steering wheel to CENTRE(turn it left) position within 4 seconds and hold it still
6. When your 4WS light turns on, turn your steering wheel to CLOCKWISE again to 45-60 degrees and hold still( again within 4 seconds)
7. When the 4WS light goes off turn it to centre position again within 4 seconds and hold it still.
8. If your 4WS light blinks twice(short bliks) then you succeeded.
If it stays on after these that means you could't erease the DTC so simply turn the ignition off and go back to step one and try again.

The tricky part with this procedure is that you should do all the steering inputs within 4 seconds so keep it in mind.

If you succeeded removing the DTC turn your ignition off, remove the short on the service connector, start your engine and check if it's working.

I know it looks complicated but it is very easy, I can do it within 2 minutes all it takes is a little practise and if you have difficulty shorting the service connector there is a plug goes into that to short it and it's part number is 07PAZ-0010100 which you can buy from Honda.

If you want to know what DTC it throws before resetting it do these:

1. Short the service connector pins
2.Turn your steering wheel to CLOCKWISE 90 degrees and keep it that way
3. Turn the ignition to II position but don't start the car
4. 4WS light will go on and off throwing the code(S)

It will be dim for 3 seconds,
After that a 1.2 sec. light means 10
Short light means 1 so if it blinks 1 long and 2 shorts it is DTC 12,
if you have more than one it will throw all of them and turn back to first one so take your time to get them correctly

We have:
DTC 10-11
DTC 20-36
DTC 40-51
DTC 60-65
DTC 72-74

When you say wait until the 4ws light is off, do you mean wait untill after the actual code and the really fast flash part, signalling the end of the code?And then immediately return the steering wheel to straight for the 2 or 3 seconds till it starts again?

Hi All,

Although this is a very old chain, I have a 4WS trouble with the following warning light sequence:

2 long flashes
pause
7 long flashes
4 short flashes

Can anyone please help?

Thanks,

Paurav
