Does anyone know how to get the engine codes out of the LS400? If so do you also have a list to determine what these codes mean??

to get the codes for 1995 lexus ls 400

1. remove the top cover from the engine, it has only 3 screws.

2. locate a plug that is called diagnosis

3. attach scanner to it.

4. scanner will give you 1 or couple of 4 digit codes.

5. gimme the codes, i have a list . so i will let u know what they mean

i think the codes that lextreme provided are for firast generation, while second generation have different codes, my codes are from alldata, and might be more up to date for 95-97 models

I was looking for any kind of recommendation for purchasing a hand held scanner. I know that autozone has one for 155.00. Just wanted know what luck you have had?

Also took the care out last night for dive. I started and ran flawlessly right up to the point of 3000 rpm and then I got a miss fire style of hesitation. If the timing belt was out the engine would run consistantly rough.

Is it possible I could get a copy of this list of DX Codes from you??

Went to lextreme this morning and down loaded the dx trouble codes without any problems?

Thanks lextreme

My neighbor has a handheld scanner which I have used on my GM cars. Works great, has a book that explains all the codes and how to use. Actually, it is very easy to use. I'll probably buy one at some point in the future but right now I have lots of other uses for my $. I'll have to check to see if his scanner fits Asian cars, then I'll just borrow that. From my experience, handheld scanners work great. I also know there is a way to check codes with a testlight probe. You have to count the number of flashes when you jump to terminals. I found this on the Internet a long time ago, but only used it on my Caprice. Might be worth a look-see.

actuall you don't need a test light

you can use a paperclip any thing to short the 2 pins side by side on the GM connector

[brentg]

Does anyone have access to a service manual and can look up this DX code error PO336 (crankshaft position sensor)? and what the fix would be????

The traction control light just pulses continually without a pause?

The car runs good, drove it this morning up to 90mph with the rpm under 2,800 without a miss. any thing above that I get a miss..
