Hi Folks,

I bought a OBD2 adapter from e bay. While it said it's for Audi / VW etc etc, I found a few sites saying the LC does use OBD2 and ISO9141 comms. This item (http://cgi.e bay.co.uk/ws/e bay.dll?ViewItem&item=230335003811) said it supports the protocol.

I though, £14 not that much of a risk.

Anyway, arrived today, tried it and nudda. Non of the software can find the car.

Anyone have any comments? (other than "you;re an idiot because it said Audi bla bla bla" Embarassed

) Should it work?

Failing that I was looking at this one: http://cgi.e bay.co.uk/ws/e bay.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=120442404474
A tad more but if it works......

Cheers,
Crispin

It seems that some of the cars have a diagnostic socket which uses the ODB2 interface while others use a Toyota interface called MODB. This means that a lot of us can't use Scangauge or similar gadgets. I think that some of the 100 series petrol engined cars have an ODB2 interface while the diesels still have an MODB interface.

I can't tell you about other models except to say it's not straightforward. There doesn't seem to be much on offer for the MODB cars and I don't think you can adapt an ODB2 reader to work with it - which is a shame as a Scangauge or similar looks like a good tool.

Hi Willy,

Can't say I've heard of MODB (not that I've heard of many things Surprised

)

I've returned the reader, much to the sellers upset, and bought another which claims it will work with Toyota. I've seen soem guys on PradoPoint in Aus who use scan guage so looks like it is possible on some versions....

Will update when I get it and try it. Holding thumbs...

So returned cable one and got a refund.
Bought another cable which the guy says does work with Toyota. Nudda. Plug cable in, all the lights come on on the unit but software will not connect to car. Says car now found (I'm sitting in it)

will try with other software over the weekend and see how thing go.

Hopefully I won't have to return this one as well. (I'm thinking I will have to though Sad

)

So I tried the cable on the wife's GT (while looking for the OBD2 socket I found the fuel pump fuse that had burnt black. Typical Alfa!), connected the cable, run the software and all is good. Connected, told me what was and was not supported. I could get real time data from it (How cool is that!!!!!)

So I know the cable works as does ProScan. Connect it again to the LC and nudda. Sat and screwed around with various protocols to no avail.
The cable apparently supports OBD, CAN, OBD2 and PWM which use different pins in the plug. Having a look at the supported cars on MyScanTool.com, Mr T does not have many entries. He has his own bag of tricks?

What do Mr Fix it folks do when they repair this. Surely there is an option for man in the street and not just dealers?

Scuse my ignorance but what the hell is an OBD2 (o b 1 kenobie - type of thing??) adapter? - what does it do? Confused

So the problem here is ..as of a set year all cars are fitted with a comman plug type "OBD2" so any garage can plug any handheld computer in and find the fault and fix your car .......

seem's toyota may have the OBD2 but the problem is finding a computer that can talk to the car Shocked

seem's toyota may have kept the program to them self's some what Crying or Very sad

But Crispin is going to spend all the cash to work this problem out to save us doing it Razz

A friend has quite a complex diagnostic system costing several thousand and that sort of works with the LCs, but only for reading error codes and resetting them and even then it was pretty sketchy. His kit was intended for testing lorries, but could talk to a lot of cars, even though he hadn't bought the car specific kit.

Unfortunately Toyota do tend to mainly use their own proprietory system that requires the Toyota Intellligent Tester II to use the full range of facilities. You can buy these, but they are expensive with prices ranging from $2000 upwards depending on where you are looking.

I looked into other 3rd party readers a while back, being particularly interested in some of the Bluetooth based ones on the basis that it makes it a lot easier to test the vehicle is you aren't permanently wired to the plug.

Talking to a few of the suppliers the general feedback was that you may find some kit that could read fault codes and some of the other readings, but you would never get the full range or be able to do things like change the User Preferences that are programmed in on 100s, 120s and later models.

From memory, in the US all cars had to be OBD-II compliant from 1996, whereas in the UK (and probably Europe) petrol vehciles had to be OBD-II compliant from 2001 and diesel vehicles from 2004.

Actually looking on e bay there is some quite useful information on this item [url=http://cgi.e bay.co.uk/WIRELESS-BLUETOOTH-OBD-II-2-OBD2-PC-INTERFACE-SCAN-TOOL_W0QQitemZ370226754641QQcmdZViewItemQQptZUK_Diagnostic_Tools_Equipment?hash=item56333bf451&_trksid=p3286.c0.m14&_trkparms=65%3A12|66%3A2|39%3A1|72%3A1689|293%3A1|294%3A50]OBD Key[/url].

Fortunately it looks like I may be able to get my hands on a second hand Toyota Intelligent Tester for sensible money. Laughing
