s14 sr20 kouki. How do you check for codes there is no light on ecu or screw??
 

i have a kouki sr20 in my 1997. I want to see if I have and codes from my ecu, But I havent been able to find any info on it at all. and my Fsm is about a zenki sr20 which has a differrent ecu. This is a ecu labeled ''NA'' and does not have any adjusting screw or light in the back of it like most sr20det ecus do. I think i remember reading somewhere a while ago that the dash check engine light blinks and that how you pull codes. But how do you get it 2 start blinking???? anyone know?

Jump 2 wires on the ecu. or goto blazt.biz order cable make it easy.

which two wires?

w w w . 2 0 0 s x . o r g
check out 4.12
Jump chk and ign
chk is diagnosis activation

I forgot which ones to jump so google found it for me.

Well I viewed 200sx.org before that same article. but jumping the 2 wires at the consult port dosent work. And read a post where someone else couldnt get it 2 work ether. I think because that article is talking about the JDM version of the s14. I need to find a pinout for a ''NA'' s14 sr20. and then see which wires need to be jumped

s15 na uses same harness as turbo IIRC. and s14 kouki u can use s15 pinout.
So you followed the process inthe article? Applying 12 volts to the chk pin should do it. It is even labeled as diagnossis activation.

only thing is now that I look at the ecu I cant find any of the wires. Im guessin the the company that did my wiring ripped out the consult wires!!! so I have to find the pinout for the ecu and put 12v to the a wire I put into the CHK slot
