does anyone have the pinout for the ecu or the mitchell book on a pdf format.

 

anybody has a link it will really help me out.

 

i am pretty sure i still have it on my computer at home. ill post it after work if i can find unless someone has it before then.

 

That's what's in the official technical manual. ECM is the ECU (engine control module or engine control unit.. same thing)



no idea if that is too vague or if you need to know what each pin on it is for.

 

this seems to be the most relevant thread to revive, mainly because it is titled exactly the way i would have titled it.

does anyone have a pinout for the 2000-2001 cars. i have spent about and hour and a half searching on here and on google and have not found a pinout guide

 

For 2000s, you can get the corresponding information on EC-149 to EC-156 of the FSM. I didn't look up the exact pages for the 2001 FSM, but it'll be in there.

 

So instead of starting a new thread with the same title, you dug up a pointless 2 year old thread with no information in it?

 

yea, repeat threads are annoying, this one is more than salvageable

so are you saying if i were looking up info in the FSM (book or cd) i could buy at this site i would be able to get it? http://www.nissan-techinfo.com/nissa...p?dept%5Fid=10

i hope someone else has the info so that dropping $200+ isnt necessary

 

There are many links to free FSM downloads floating around on the .Org. Use the advanced search feature to find them.

 

well i get again...

Glad to see you found one of em.

 

just by looking through the FSM for about 30 minutes, i found that the ECM description is on EC-114 through EC-121

VIAS control solenoid - 16
Tachometer - 25
MAF - 61
Knock Sensor - 93

Throttle Position Switch (closed position) - 56
Throttle Position sensor signal output - 82
Throttle Postion sensor - 91

ECM Ground - 48
ECM Ground - 57
ECM Ground - 106
ECM Ground - 108

ECM Power - 110
ECM Power - 112

 

Not sure why your page numbers are so different, but the pins look right.

I'd use pin 91 for the throttle wire because that is the TPS wire to the ECU. Just check the voltages and % throttle reading at idle (0% throttle) and at WOT (100% throttle) on the VAFC to see that they are within the FSM specs.

 

Btw, just so you know I'm not on crack, here's a copy of the 2000 FSM EC-155 with some of the pin descriptions and specs:



There is also actually a 2000.5 FSM, but that same page is EC-156 in that manual.

 

i thought that pin 91 would be the one to use, what about the four ground wires and two powers wires, just use one of them?

thanks for the responses, hope this helps out other 2k owners.

 

I believe you can use either power wire as long as voltage is close to battery voltage, and almost any ground wire. For example, I followed Jime's writeup and use pin 48 for ground, while SR20DEN uses pin 106 or 108.

Studman's SAFCII diagram actually says not to use any ECM wires for ground, but no one else seems to be bothered by that, so I'm not sure about that. Unless I'm misunderstanding what he was trying to say.
