Checking Codes on JDM ECU - Honda Prelude Forum

JustXtreme · 05-27-2006, 07:34 PM

I have a JDM type S engine and ECU, i need to know how to check the engine codes? I've seen the write up but when i do it the engine light stays solid. I also took it up to autozone to hook it up to there obd2 code reader and was unable to connect. Please Help, something isn't right with my car.
I dyno'd at 162 hp and 126 tq today, these seem low to me.

japan doesnt have obd-2 so i doubt the code reader will be able to read it.

JustXtreme · 11-14-2006, 12:36 PM

what does japan have?

OBD2 is an SAE/EPA thing. I don't think there are any requirements for a common standard in Japan- I suspect it's left up to the mfr. as to the implementation.

The idea here was to have a common standard so that cars could identify when emissions equipment wasn't working, alert the driver, and independent inspection stations and service shops can easily identify problems.

marcucci is dead on. Japan has relatively lenient emmissions because they are on an island and most people there barely put 3-9K miles per year on their cars....

marcucci · 11-15-2006, 08:32 AM

Japan is actually not that lenient on emissions- they just don't measure them like we do. They are also more strict in that ALL vehicles are required to meet the same standard, not just the standard that existed at the time. So, for instance, if you buy a 510 that you want to turn into a drift car, you may have to meet 1975 emissions standards in the US or no emissions due to the age (depending on where in the US you live). In Japan you would have to bring it up to the current standard or simply not drive it in the US.

In Japan you will notice that you virtually NEVER see old cars on the road... hence why so many of them end up chopped up and sent to the US.

so no one knows how to check the codes.

I know. I used to live in Japan. The main reason you dont see old cars on the road is because of culture to always have a nice, new car, and also because parts and labor is prohibively expensive. For example, I saw cars in junkyards with bad headgaskets, transmission that went out, etc. I drove a 3rd gen RX7 when I was there, and I had aftermarket exhaust, intakes, Pan speed ECU, Feed front pipe and I still passed JCI (their vehicle inspection). Occasionally you still see older cars but not too much due to age, repair costs, rust and other factors....
