hi all i have this issue with my 4ws not working read the code which i think is 71, seems the ecu suffers from bad solder joints to the main relays , is there anything else i need to check why i have the ecu apart

Apart from those solder joints they are pretty robust, mine is 26 years old and has had no other issues.................

thats good to no am so hoping this sorts my problem

I never opened any of these units but i suppose that they should have some capacitors on the board.
So if you open it, it surely be a good thing to replace them, as the aluminium electrolitic capacitors are known to leak when become old.

refitted the ecu today and hey presto no more 4ws warning light staying on but still no steering from the rear it just does like a little twitch and thats it no real movement its almost like the rear steering rack is jammed so looks like i am going to need to give the rack the once over

That's a bummer.
Check that no-one has fitted a locking pin?

hoping to have more free time next weekend and will check this need to jack rear up to check for the abs fault and exhaust has a blow somewhere

it seems this post kinda runs with another i have for this car but thought i would post my findings here as it completes this post to a finish which may help others , having overcome some other problems i finally got the car into the workshop and over the pit to check the rear rack over and sure enough someone had fitted a locking pin , once this was removed i have a fully working 4ws system so if you have a 4ws fault first check is the ecu solder joints anyone who isnt up to doing the soldering if you cover the p@p i am happy to do the soldering for free

@firstlude, what exactly does the locking pin look like when inserted into the 4WS unit?

Blimey, amazing that someone had fitted a locking pin and not removed (and even more amazing that it hasn't damaged the rack/motor/ecu on the rear setup, as a result of it being in there so long with the car driven!)

Anyway, glad you've got it sorted
