can  someone tell me if the 1996 ls 400 ecus are immobilised or not its the none vvti one am i right in thinking that immobilisation came on or after 1998 

hi everyone just wondered if anyone knows where i can get a replacement lcd and someone to solder it in for my lexus ls400 pioneer radio

model number kex-m9076zt the part number for the lcd is cwm5077  found 1 in the states but out of stock hoping there is someone in the uk who can do the job

wanting to swap my engine ecu on my 1996 las 400 can anyone tell me if this is just plug and play or does it need to be coded in to the car 

hi  this is rather a complicated and drawn out post so bear with me 

we have a 1996 ls 400 some weeks ago we lost a secondary 02 sensor had this replaced only to find   we had the dreaded split egr pipe (forgot to say car has been converted to lpg ) we did the delete rather than replace the pipe still have valve connected but blanked off sinc doing the delete car runs OK but will not accelerate properly and uses excessive fuel (like 1 mile to £1 of fuel) not good also wont switch over to gas as quickly as before its an obd1 and have managed to get some codes out which are as follows 21,27,28,29,31.71 replaced air filter and tried to clear the codes but they are still there ordered another maf thinking that might be the problem but am now at my wits end trying to sort this out car ran well before the lambda senser blew out although it had a blow on the exhaust which was welded up heres hoping that someone on here can help please just 1 other thing car used to start 1st time every time before this trouble now it takes 2 or 3 goes to get her going

since having the Battery off to charge i have a slight prob when u open the left front door on the dash it says right front and vice versa is ther something ive done wrong or can it be reset everything else works fine

Hello Bob,

I have the OEM electrical manual for the 2000 LS400 and fortunately can understand it, the common factor is the 40A AM1 fuse located in the engine bay fuse board it should be at the opposite side of the AM2 fuse ( may be shown on the inside of the fuse box cover).

This fuse feeds both front doors via 2 seperate 20A fuses which are constantly live and also feeds the heater,wipers,gauge,indicators,ECU 1G and PWR 1G circuits via individual fuses, the last one PWR 1G feeds the ignition main relay which may be the reason the car fails to start but turns over.

So check fuse AM1 rated at 40 Amp and please come back and let us know the outcome.

cheers 4 that is there any chance u could email me a wiring diagram for this section we are talkin about please

Hello Bob.  I have the same year and model. The items you list as working are

all direct feed, whereas the other non-working items are all ignition controlled.

Sounds to me as if you have lost feed from the ignition switch to fuse box.

Did the steering column move on inserting the key?

Hope this helps a bit !  Les

no column didn t move but the car turns over on the key which is past the ignition controled items its weird

this may have been on before but heho here goes drove car home as normal and left it 4 a few days went to start it as normal car started but no dash lights no radio heater sat nav front central locking computer indicators wipers speedo rev counter  but headlight hazards leccy seats horn all work awe by the way cant get out of park unless u use the overide button 

checked the 120amp white alternator fuse also 80 amp main fuse also 30 amp amp2 fuse replaced them all Battery seems ok  immobiliser only works if u lock the front 2 doors on the key cause they wont lock on the button  didnt do owt with it just stood for a few days and all this happened anyone any ideas why
