So I'm currently restoring a year 2000, S2000. After changing the battery and also a lot of fluids including brake, it now is giving me a ABS Light on the dash.

So I thought ok I'll read the codes via the OBD2. Well that didn't go to plan, tried everything to get my reader to work with it but to no avail. So i decided to check the wiring behind the OBD2 port.

OBD2 port hasn't got enough wires
Brown service wire back of the ECU
Would appear my OBD2 isn't wired correctly for a normal reader. This might be due to the age of the car .Any suggestions?

I finally was able to get the car to blink me some codes by grounding the Brown DTC wire on the ECU.

The codes it blinked where

ESP Blinks 0-7, 3-4
ABS Blinks 1-5

Does anyone know of a place I can find out what these correspond too?

Any help would be appreciated or it'll be a no doubt expensive trip to the Honda dealer.
