    Default Elesys WL81, what is this?

    On my 2007 2.5WLT 4x4 I traced a dead wire to this unit.
    but what is this unit?

    it sits in the footwell at the drivers door...

    Thanks prof, but a control unit for what? I have had a look on the google machine but canít seem to find any conclusive info.

    the dead wire I traced to it is the wire that gives power to a solenoid on the back of the mechanical fuel pump.

    That wire is intermittently dead, and then the car wonít start. If I give it 12v direct from the battery, car starts no problem, but wonít switch off with the key, I have to disconnect the 12v.

    Fitting a simple switch and relay is a way to sort it out, but I donít want to give that solenoid the incorrect voltage and current for extended periods and cause any other bits to fail, or make the car any easier to steal.

    I highly doubt it has to do with the powersteering.

    The box controls idle speed, rfw hub, relays, etc. I had a problem with a cold solder joint on mine (wl81 box) that caused the aircon to stop working. I replaced the wl81 box and all was fine. I think the 3 relays in the left side of the engine bay is controlled by the unit. One of those relays broke and caused a no start failure on a friend's 2.5. Replaced relay and bakkie started.
    Check the soldering in the wl81 box. New one is very expensive

    Thanks guys.

    i do have a pdf version of the wiring diagram but for some reason I can only see like 60% of the page..... I will try again on another pc.

    I will try look through the board for any visible dry joints, and maybe get a ate of mine to take a look at it. Thatíll be 1st prize. Hopefully non of the ICís are fubar

    Not properly unfortunately

    I located a replacement unit in Durban, but the seller wants to charge me R750 to plug it into my car to see if it solves the problem, then if it does solve it, and I want to take it, its another R950 on top....

    I understand why he charges for pretty much "diagnostics" but I'm not paying that kind of money....

    so I simply put a switched live for the dead circuits that I have via the fuse box that activates with the key
