An into to my lc5, it appears as it arrived. It's last mot expired on the 13th of March 2020. I believe it was last running correctly late 2019.
It has covered circa 94 000 miles.... it has full Toyota service history to 70 k miles and am very grateful for the forum member who donated it to me.
As all 120's look good on the upper side, this one is outstanding on the underside.. there's rust on the weld joints on the chassis, the rear behind the bumper and the front radiator support.
It has previously had some undercoating but it is flaking off the body. Thank fully it's not orange on the under carriage!
Since last use it has developed the no start syndrome, it fires momentarily then turns over very rapidly. And that's it!
When it arrived the dash was semi dissembled in a bid to get to the core of the electrical problem, but when I reassembled the dashboard and connected the batteries .. in a bid to just see what was going on. it fired straight up. ????
I managed to drive it 6 miles to my local fuel distributor who kindly let me hot wash the truck and then fill it with fuel, as the air suspension was leaking from one of the rear air springs it was a very slow drive running on the bump stops so don't know if it was running in limp mode.
Made it home and the next time I went to move it no start just the typical scenario of a faulty scv whether or not it was the culprit., I changed it to the revised longer one replacing the shorter one said to be unreliable as time goes by. There's a difference between the 1st and 2nd versions of the scv's the earlier pushes and the revised pulls.. and this occurs on every stroke of the firing of the engine. So indeed a very active component! And prone to wear.
I think that this is integral to the immobiliser as it cuts of the fuel supply and people have had the B 2xxx fault code resulting from having a faulty scv.
This is the last pic of it that I have but have swapped out the suspension to a pedders air suspension replacement coil rear and front swap too +50mm.
Have removed a 10 amp fuse and the air sus 50 amp fuse contained in the under bonnet fuse box and also have disconnected the connector from the air susp ecu which is housed in the passenger side lower kick panel it's the further most connector to the rear of the truck. This has deactivated the flashing air sus warning lights on the dash and the switch circuit. This is the guidance from pedders susp. The air suspension circuit is deactivated and not connected to the initial problem of no start.
This pic was taken on 3/07/23 and it then was apparent to have the capability of reading the codes on the truck... and this is where the troubles were extended. (before even working out the core issue with this 120's immobiliser) .. have activated techstream v18 but failure of connecting the vim module mini vci j2534.. which is an early 32 bit compatible interface which works best on earlier versions of windows, after much research it does work on a 64 bit windows 10 some do but some will struggle to enable techstream to connect to the ecu. Have seen a guy who has run this off a windows 10 64 bit with a windows xp extension to make it work
This is the beginning of this particular problem and only scratching the surface of the story so far but just an intro into what I have found out so far.. I really like this lc5 and it's condition so deserves for it to be solved..
More to come...
