Ecu Diagnosis - R32 Gtst Rb20det

[Lithius]

Hey i'm just trying to diagnose a recent problem I've been having, just having a little trouble with the standard ECU in my rb20det. I have the service manual and have read the posts on here about ECCS codes, i just can't find where the green or red LED flashes are supposed to occur. Do I have to unscrew the ECU from the footwall to see them? The picture below is how it is seated... From what I can gather the lights should flash from the bottom of it? But when I look there's nothing there.

Edit: Just did some google searching and discovered the LEDs face the front of the car! so i'll have to remove it from the footwall. What a strange place to put them... Sorry for that, only reason i didn't remove it before posting is because the screws are so tight my screwdrivers just spin. I don't see a way to delete this thread but if a mod sees it please delete, thanks.

If you activate the diagnostics thru the consult port method, the "check engine" light in the instrument cluster flashes the codes.

found the same thing on my silvia ages ago - seems stupid!

my r31 has the LED's to the back of the car, and even has holes in carpeting where u can read them thru and turn the screw on the ecu also. looks like theyve gone backwards since then
