Does Anyone Know Part # of the First ECM

[jime]

Honda has done a very wide service recall on one/all of the original ECMs because the car did not meet polution standards. There has been a lot of discussion of this replacement program, but no one has been able to identify the original ECM part number. I think it would be worthwhile to find out the # of the original part. I would expect the part number to be of the form:

37820-PHM-3xx , where the x's signify the missing parts of the number.

1. You might find the original part # on your replacement service invoice,
2. You might be able to get your Honda dealer to pull up the #,
3 You might be a Honda tech and know the answer,
4. You may know someone who knows the #.

I'm pretty sure that the early cars, say 2000-2003 would be the most likely to be sources of information. We already know that they were correcting the problem after those approximate dates.

Thanks, it would be a service to us all!

I know my previously failed ECM does have one of the first ECM ever made for this car. I don't have it on me right now but I believe it is 37820-PHM-355. My car was built on Nov 1999. I can check when I get home.

I got a 37820-PHM-345 on Ebay. I thought I heard of someone mentioning a 318?

That's probably what I was thinking. Must be my MOPAR tendencies showing through.

Near as I can piece the story together, that means you had the service recall and the dealer installed a 505 for whatever you originally had. It kinda looks like Honda, at some point, started installing the flashable 505 and 506. Some folks got 3xx series in the recall, and some other folks seem to have gotten 50x series. The logic I don't understand, probably depends on when Honda did the recall. Just guessing.

Please put your info in the spreadsheet here:

If you know when the recall service was done, that would be helpful info in the "comments" block.

Thanks.

There were 2 different recalls, the first one replaced the original with the high 3xx series, and the second one replaced the original with the 505 (for 2000s) and the 506 (for 2001s).

That is very interesting information and the spreadsheet seems to agree with this assessment. Can you provide any additional detail such as service bulletin numbers and dates. Just asking

It appears not so exclusively... to add to the confusion:

My '2000' model, S/N in my sig, Cdn. equipped vehicle has a '506' indicated on service records, replaced in 2008 per K66 recall.
fwiw: My car was only sold off of the Honda lot in the spring of 2001.

The service record from Honda West in Calgary indicates:

Engine MIL light on.
