I never thought it could be so simple to read codes.

I went for a drive across to Jaycar Hornsby and I purchased exactly what you described and..... Absolutely fantastic.

I have 1 code for KOEO and
1 code for KOER... Now I need to find out what they mean...

KOEO - 157
KOER - 998

Looks like my MAF is buggared!? But I replaced it only 12 mths ago. Might put the old one on and see what happens...

Can't wait to try it out...

IMO you can't beat Murrays...

Yeah this works and its cheap (and seems some what primitive compared to testing devices)...

Murrays is easy... Plug it it in... Turn switch to "on" and display in numerical form all the codes so no counting... and if you have it pluged into a a computer you can walk off because the PC will log them all in a list... Worth every cent if you ask me...

It's not hard...

Shorting the two pins puts the computer in diag mode... The computer proceeds to ground a pin in a series of pulses so to see this you need power to a light and then ground wire to the pulses pin and as the pin grounds, the light comes on... Shock horror amazement :?

Welcome to the days before propriety software and information formats that make this type of DIY testing impossible on your own car with everything from AU onwards...

Cheers,
Tim

I am still having trouble with the AU IAT sensor does any one now how to test it I Have the specs for the EL one but I can't get a reading from the AU IAT.
I have attached the docs that I used to test these Sensors.
Thanks


i may be wrong but all au's use an integral ait and map sensor making it completely incompatable with earlier models ? even to the point i don't know how you fitted it.

sorry... are you saying you bought a test light and it does the job?? how do you hook it up to the test socket..?


Yeah mate. First make sure the ignition key is turned to OFF and the trans is in Neutrel. I made up a bridging wire - so a spade terminal on each end of a wire... And connect this with one end pushed onto the top far left terminal or A terminal...
Then I bought a 12v led light which has negative and positive colored wires and crimp 2x smallest alligator clips in the end of these wires.

Then connect the black or negative wire to the top 5th from the left or E terminal which is Engine STO and the red wire to the bottom far right terminal or T terminal...

When u do this the red LED (which I bought) should light up.

Turn the ignition to ON. Don't start the engine... Yet...

As you do this called the KOEO key on engine off, there will be a quick flutter from the light... And the several code 10's which will read as 1... 1... 1... And this will repeat... Some people get confused here and think this 111 is system pass... But wait... For me after this I got code 157... This repeated twice and then no more flashing...

Now for the KOER, key on engine running...
Leave everything plugged in the same way...

Start the engine... After a few seconds the engine with rev up and hold at about 2000rpm and watch for more codes, if any... Once all the codes have repeated and finished, the engine will return to idle...

I will add a picture of my test diagnostic gear so you can see... :)

Edit - when you connect the bridging wire to Terminal A make sure you connect the other end of the wire to the terminal directly below it, terminal L :)

A bit earlier someone asked if a sparkies screwdriver type of thing would work as a test light...sorry but I don't think it will. Those normally have a neon light in them instead of a LED and are designed for 240vAC (not 12v/5vDC like we want for our ECU test light)

When I made mine I put the LED inside an old texta/pen shell, shows up better in the sun
