From Jaycar I spose all you guys have one of these:

OBD II LCD Scan Tool


If you have a late model car, it will probably have an OBD (On-Board Diagnostics) connector. If it was manufactured after 1996, it will support the OBD II protocols. This OBD II Scan Tool supports the CAN (Controller Area Network) protocol and can be used to diagnose prior to repair and to verify a repair after service. It also turns off check engine lights, erases diagnostic trouble codes and resets OBD II monitor status. Save time and money on repairs, identify problems with a used car before buying or analyse engine performance data.

Can be used to check the VIN number when purchasing a second hand car!

Features:
* Suits all 1996 and later OBD II compliant vehicles
* Supports multiple trouble code requests: generic, pending, and manufacturer specific codes
* Retrieves VIN (Vehicle ID No.) on 2002 and later vehicles
* Two line backlit LCD
* Dimensions: 115(L) x 75(W) x 20(D)mm
* Cable length 560mm

NOTE:
For the most current DTC Library and user manuals please download from the following web site - http://www.auteltech.com/
QTY
1+ $129.00
3+ $115.95
6+ $102.95

CAT. NO. QP2294

Seems to me to be a desirable bit of kit, handy to have even if you are getting your car serviced by a 3rd party, you would know exactly the problem before you had anyone do any work.

All modern vehicles have On Board Diagnostics (OBD). Pre 1996, only dedicated readers could access the OBD, these readers were not available for the average joe to buy. That all changed in 1996, the U.S. gov forced the manufacturers to allow joe to plug and play - OBD11 was born. Every vehicle that can be legally sold in Nth America must have a compliant OBD11 terminal.

Most vehicles in Australia also have an OBD11 terminal but a lot of them are not yet compliant with these scanners that are flooding our market. It's a suck it and see scenario, for now.

Basil,

quite a few of us have a Scangauge from here:

Wooder's Garage

The codes are not a standard thing (I believe) but the info provided, like fuel consumption etc, is great.

The Jaycar item is not quite the same. If you look on the manufacturer's website they have a tripmeter which looks like it's the same but I don't think Jaycar stock it.

Anyway, there's an option for you.
I'm glad I ain't too scared to be lazy

Seems to have the same functions as the Scangauge, just looks a little different.

I bought a Scanguage from Wooders based on the US site listing for my 2002 Landcruiser GXL non turbo. Buggered if I can find the OBD port. Looked everywhere. Any suggestions would be appreciated.

Cheers

The OBD port 'should' be within 1 - 2 mtrs of the drivers sitting postion.

Normally it will be near your right knee, suggest you look behind the fuse panels that are pften located near there.

It is a white/translusent plastic multipin fitting

Phoned my local Jaycar store and quizzed about said item. The "expert" who took my call assured me that it would read all the OBD II codes as they are standard by american and Japanese manufacturers and a "library" can be downloaded to make the thing work with some European vehicles, Audi, Mercedes, etc.
He claimed that my Jack 2002 TD was an Isuzu ( correct) and the engine was designed by "caterpillar" and according to the information he had the OBD II LCD Scan Tool should work "faultlesly".....Offered a money back guarantee if it did not perform as stated. I may invest in one and I can then trawl the car yards and find out what it is compatible with...

OBD II Standard with CAN D bus contains only a small subset of codes and sensors between manufacturers. Each manufacturer has a vast amount of proprietary codes for a model series. If you run an onboard computer (many do now) you can get live data and monitor or even optimise your engine and understand whats going on when you put the foot down with that 25' caravan hanging off you.

I have considered this tool
http://www.autoenginuity.com/ a long time ago, but they had no OEM extension for my truck until recently. I have a TECHII for my truck with a CAN D module but there are limitations because it is original GM software and they do not provide tire calibration for the transmission for example only by model not freely by tyre size. Also speedo corrections depending on tyre size can not be done with the original GM software. I will get above software with the OEM module for my vehicle just for the kicks. It's cheap for what it is really but I do not have a clue if it would work on the local cars with the OEM extensions. KIA, Land Rover, BMW etc should be more likely because their models are closer to ours here. Not so Toyota but if someone is interested I will have a version here soon running on one of my laptops and the on-board computer.

have fun
