Hi all im a bit confused just looked at my Ecu so i could do the test i have a red led i can see on the side but not screw/switch to put it in to the right mode?

 

is there another way to do the test to see if there are any fault codes, im abit stumped now ,

 

Thanks in advance , wayne

you doing a fault diagnostic?

yeah mate its the 1st 300 ive had so dont no anything about them :(

the screw is set partialy in the ecu next to the led it easier to take out the 3 screws that hold the ecu in place you can see the screw then

ah great thanks Tommy

It's much easier to short the correct pins on the diag port, then it displays on the dashboard.

so the screw is inside the ecu next to the red led yeah ?

how do i do that Andy i think that would be easier

Thanks guys your stars

yup just turn ignition on then turn screw to the left for a couple of secs then turn to the right ,the led will flash along with your engine management light

just looked theres no screw there at all :O

 

been looking on jim wolfs ecu identification list with the serial numbers of the ecu .. mine isnt there A18-A98 MD7

sorry guys another question do i leave the jumper wire in for 3 sec's then take it out?

post a pic of it up mate

i cant at the moment Tommy im not at home , no cam here , also in big bold letters is UJ ,

 

does anyone have a link on how to do this test from start to finish lol im a bit blonde i think today

right now im stuck , there's no screw to turn near the led and i cant get it to work with the jumper wire , ffs :headvswal

ok sorry i dont know how to do links ,but type fault codes in search tab down to the result starting in "codes" go into that post ,go down to legraths reply and tab on to 1st method, this shows you step by step with pictures

There should be a small hole with a sticker with a circular arrow around it. The screw (is actually a potentiometer) and is inside the ECU.

Make sure you are using the correct pins - check the plug has one square end and one bevelled end.

 

 

Ignition on, engine not started, plug in wire for a few secs and look at the ECU light on the dashboard. I think it repeats the codes until you turn off the ignition.

Nope theres nothing there :(

 

Right i put the jumper wire into the connection plug and the only thing that happenes is the engine check light goes out, waited for 3seconds or more and nothing no flash from the engine light or anything :(

is your ecu the same as the one in the pic

lol ok got it working lol told ya i was being blonde i forgot to take the jump wire out lol

its giving me 5 slow flashes and 5 fast flashes

ok :) thats shows no faults recorded then

great after all that i wanted to find some thing lol joking

right just took it up the road and tested it again its cam up with codes 34 det sensor circuit

Right guys ive found the problem its none of the above its to do with the cas just went to check the timing and was out so set it to the 15 deg btdc but when you tighten the bols up the car cuts out??? any idea's

or should i start a new thread
