hi, arthur
what ciruit #15 are you talking about?
circuit #15 for ecu or for what module?
i am confuse plz explain cuz i have searched and found abs control unit circuit 15 is heading toward the charging system
and for computer module it is heading to ward air injection pump? am i looking at right place?

key on engine off no i do not have the CE light on - check engine light. i have checked the bulb and it is good.

Do you want to answer my questions at each step?? Forget about circuit5 15 for now..I am trying to get through some test..
I repeat:
DO YOU HAVE A CE LAMP with key on/engine off at the dash...yes or no????

no

[QUOTE=usman21;1510413] no


Thank You very much..

Can you handle building this??

k i have finishing making the tool. i went to radio shack yesterday to buy the stuff i need. one question i have is that where do i the middle plug goes to?

Veru good..but you are ahead of me..I need one more step

Go to fuse # 9 and take your test lamp/meter [ whatever you used for the last voltage test] and I want you to test BOTH sides of that fuse..do not touch the fuse ends, but rather the fuse holder connectors..each side ...pos lead to fuse , neg to a good ground. KOEO...

hi, arthur i have tested both sides of the fuse i am getting 11.98 volt at KOEO.
i am getting 12.22v at engine off and key off.

OK

Lets see what you have for codes .
Te tool is used the same as the built-in led combo..You use red at pin #16, blk at #1 and use the odd one at pin 8. That will be HFM/SFI engine management module. Get them first and then go get the ones at #14. That should have codes for the ASR/ABS ..
We will go back for DM codes later. I want to be sure we can access the others first b/c I suspect your CE lamp module has been diconnected in order to sell you the car w/o a CE Lamp Warning system operating .
Meaning they had emmissions fault codes stored and did not want a perspective buyer to know about it. That is why I wanted positive confirmation of fuse #9..that powers the DM CE lamp module..
See what you have at 8 amd 14 , if any

hi arthur the led just blink solid does not flash on both system?
just solid and thats it .

Ok
So that I understand you correctly..
you put KOEO--you hooked up tool and went to pin 8-- you pressed the button, it lit and you held the button down for 2/3 secs and released---you waited a couple of secs and nothing came back in Flash Format ????
But it came back as solid 4 sec?????

hi, arthur i was doing all wrong
and i finally got it thanks to you =)

on pin #8 i get code 42 after pressing the button for 2/3 sec it started to flash and it flashed 42 times= code 42?

on pin # 14 i got code #5

Did you do it again after those codes to see if there were any more ?

yes i did and i got the same code again.

Ok
If they repeat, that means that is all the codes for those modules.
The codes come up in numerical sequence , so any time you go for codes , after one flashes back, repeat the procedure b/c there may be another hiding behind that one , with a higher number of flashes [ ie 4, 7. 9. 12 . etc] You know you are done when the first one repeats.
So, you have a problem with the Cruise set switch and you have no cummunication with the DM module.

Now , same deal..but this time I want you to go get the codes from pin #3 .That is the same as the built-in led, so that will tell you if it is the DM circuit or the sw/led.

I also would like you to try using the built-in led again , as I am now not so sure you knew how to get the codes from before.
