Does Anyone Know Part # of the First ECM

[jime]

Since the 505 and 506 are programmable, perhaps they are interchangable with the correct Honda programming??? Sure would be nice to have a Honda tech speak to that issue.

Aha! I just checked my more recent Honda maintenance receipts and discovered that my ECM was replaced a second time, April, 2009, with model 37820-PHM-505 just as racer26 stated (spreadsheet updated).

I checked for recalls against my VIN at this site:

Honda Automobile Recall Information

I only see one recall involving ECM. Perhaps your second ECM was not a recall but a warranty replacement associated with a battery claim??? See if you get the same results for your VIN, please. The Canadian version might have actually had two formal recalls, but my U.S. 2001 only had one.

That's what Honda Owner Link shows for my 2000 Insight as well, but both of my Honda service receipts describe the reason for replacing the ECM as "recall".

My second ECM replacement was described as a "product update" in Service Bulletin 07-038. So I guess it's not an official recall. This service bulletin describes the defective part as 37820-PHM-345 and the replacement parts as 37820-PHM-505 (2000 Insight) and 37820-PHM-506 (2001 Insight).

Sorry about reviving an old thread, but I was browsing Ebay today and found a PHM 316 ECU. The 345 I had developed an annoying habit of throwing an error code for the V-tec system. I swapped my 505 back in and the error code went away. I may have to add to my collection again.

I have a PHM-316 ECU on it's way to me. It may be nearly a month until I can get it in a try it out though. I should receive it by next Tuesday however, I'll need to ship it to CA to have the immobilizer modified/disabled then sent back. At the moment, the person doing the mod is currently out of a crucial part for about two weeks so with shipping times, it will be around Christmas or after. Should be interesting results.

Are the 3xx ECMs older than the Axx ones? I'd think not. I have an A02, I've seen A04 and A25 in the spreadsheet... Anyone know the/some differences among models?

Hmm. Insight #1 hasn't had the P0420 recall done. I should check it out. It's a 2001 though, so probably wouldn't have the earliest ECMs.

I should go look at mine-never been changed.

My 316 came today. Now all I have to do is get it sent out to get the immobilzer chip "tweaked."
