I cant find a list of diagnostic codes for my itr ecu. Does anyone know what they might be? Or at least know of a link to see them. Also, which pins would I jumper at the ecu to get the codes? My car does not have a jumper plug because the wiring was modified and minimalized. Thanks for any help.

 

your screwed in short. the jumper plug is what was used. if someone hacked your car up you're going to be stuck trying to find a schematic and follow it to the ecu

if you have a hard failure you could also start the car on an american p72 and read codes via a scan tool in the obd port

 

The car has always ran fine. I just dont know which two wires to jump. If I had a jdm wiring diagram I could figure it out on my own. My car does not have the jumper wiring because it is a 2000 integra gs with jdm itr swap. Short of learning to read japanese is there a way to find info? All I need is ecu pin out and diagnostic codes.

 

you would probably have an easier time using an obd2a usdm ecu for pulling codes

i've been around these cars for 10 years and have never seen what you're looking for online

if you had a usdm gsr or itr harness you could trace down the wires are see where they lead

the wiring for the jumper is no different usdm to jdm, i remember pulling codes on a p73-003 via the old school method in my old gsr
