Hi All,

The 4WS warning light has just come on in my Prelude and the Rear steering has stopped working.

This happened after I replaced my front mudflaps and had wheels on full lock.

I have checked the fuse in the engine bay and it is OK

Does anyone have any advice on what the problem could be? I have never had any bother with the 4WS before.

Thanks
Ken,

 

If you have the wheels turned on full lock for longer than a few minutes, the 4ws system disables itself and it will need resetting.

Find the service connetor.
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

 

i never knew the 5th gen ludes had 4ws...thats freakin awesome..again the US misses out on something good

 

Thanks for the help

I will try this later!

 

Thanks a million!
I've been driving prelude for more than a year and 4ws has been disabled all this time. After replacement of abs control unit 4ws started to work but then stoped after 20 meters run.
Then we replaced slightly damaged electronic unit, which controls cruise control (it worked but might produce errors sometimes) and smth else. But 4ws still didn't work with either abs control unit.
Yesterday I saw your post, and I thought that we might just need to reset 4ws errors.
Today in the morning I did this and it worked!

 

Hi BritishDude,

I know your post is quiet old, but thought if anyone could help...

I have a 5th gen 202 VTECH Prelude. Overall it is in a very good condition and the 4WS was working perfectly till few days back.

Now, the 4WS light is constantly on while the car is driving or ignition is on.

I saw this post and tried to fix it but the problems is not resolved and on doing any task, after shorting the circuit, I keep getting the following flashes of the 4WS light:

2 long light flashes
long gap
7 long light flashes
4 very quick short flashes

Can anyone please help me resolve or troubleshoot the issues further?

Thanks,

Paurav

 

Just thought I would write a quick post regarding the 4WS reset. The post above mentioned that he kept just getting the diagnostic codes. I just kept getting this, until I reread the post prior which mentioned putting the steering wheel at 90 degrees to the get the codes. So to reset, make sure the steering wheel just goes to 45 degrees - this is quite a small movement (turning the wheel to 2 o'clock position). Once I did this, it worked first time! Just an amazing feeling to have the 4WS back. Thanks to all who contribute to forums out there!!
