Hi there

I'm looking for a wiring/electrical diagram for 5th gen 4WS system. A friend of mine has a nasty problem (two codes reported) and even though we replaced two of the sensors and the ECU, the errors still remain.

Error codes: 20 and 74

Thanks in advance!

sorry this is my translate from Slovak manual

20 - output from front main or assist sensor doesn´t answear
74 - brake switch fault

We managed to decode the errors but even though we changed the related sensors and the ECU the problem still exists.
I'm looking for a wiring diagram to try to check the cables one by one, if possible.

I couldn´t find manual in English when I was doing my swap from 2ws to 4ws.

Also no one on this forum has something.

Did you try to do reset of 4ws ECU?

Here is maybe only one existing electrical scheme on this forum. But in Czech language (colours of cables are in English) . If you need help with translate some words, just tell me.

Thanks a lot, mate! What is the recommended procedure for resetting the 4WS system?

uff OK I will try describe :

hand brake on
connect service connector with wire
turn the steering wheel in a clockwise - 65 degrees and hold it
turn the ignition on (but not start the engine)
after the 4ws indicator light on dashboard goes off turn the steering wheel into the straight position
after the 4ws indicator light goes on again turn the steering wheel in a clockwise - 65 degrees and hold it
after the 4ws indicator light on dashboard goes off turn the steering wheel into the straight position
thenn should the indicator light blik twice and it means ecu codes are deleted

maybe someone can correct my english

There is no need to correct your English, I understand you very well.
Thanks!

no problem

let me know, if it help
