Ok, on a *recent* attempt to fullfill my end of the warrenty contract my vehicle was tampered with at the dealership. When I recieved it back their were NO codes, NO check engine light, NO ima light and EVERYTHING seemed to be working like it usually. Regular assist, Regual charge, normal millage. It was claimed the tow truck driver disconnected the battery (yeah right)

With 1500km left on the warrnety i realized I may have seriously been screwed once again. 3 days of driving and like i said above, everything was working.


From all the posts a few months back about scan guage i had returned my regualr OBD2 scanner and picked one up and was using it as an info/code scanner.

With PC hardware, to test for failure you do a stress test. Run prime 95, Memtest 86+ ETC so what would be a "Stress test" for the IMA system to show fault in a deteriorated pack?

What I did was drove my insight under full accelleration SHIFTING early (almost to the point of stall) so that full assist would be achieved for the maximum amount of time, with the least amount of speed. I did this on a fairly large hill with an open straight away above.

Now here is where it gets interesting. The insight accelerated like normal all the way through the gears, but right near the peak of the hill something strange happened. The scanguage show a drop from the steady 13.9V 12v system monitor to 12.1V, then, seconds later the Assist guage CUT in half, and then completly disappeared and went offline. The voltage then jumped back up to 13.9V and I experienced what seemed to be a "Normal" recall, but at the end of it the IMA light and check engine light came back on.

This mixed in with the "Testimonials" of failures one the insight by people driving once a week (which i did to recieve the codes initially) brings me to the theorey that to show a failure your insight has to be put into a stress zone, Either Full battery discharge, or minimal battery charge.

It would be interesting if the people who have high millage insights, who perseave battery problems to put their millage aside for one day and try and reproduce what I did and confirm my theory. If we can come up with a standard for how stress test your pack yourself, it may be extremly benificial to other owners

Stress testing is how you find the faults in almost any system.

You probably saw the 12V battery voltage decrease since the car will shut off the DC-DC converter under high IMA draws.
I think your right (I just read the DC-DC knowledge base). What im proposing is that maybe if a recall can be proven as happening right after the MCM takes the Dc-dc converter offline momentarily, that would prove IMA failure even if a light is not shown?

In my mind, any excessive amount of recals after high IMA draws proves there's something wrong with the pack. If my car recaled at all I would be looking at it closely for the next few days since I have never experienced such an event aside from when the 12V batter was disconnected.

Of course, Honda would probably have other ideas.

Of course Honda have other ideas, my Insight is now for 5 months at the dealer due to the battery detoriation (dtc 77 code) problem. So they decided to replace the BCM and the MCM because of a bad battery pack :? . They asked me to testdrive it and I found out that the car was even worser than it was before, I said that the battery pack is bad. To shorten this message about that I am right in this or not, Honda send a few people from the main office with an Insight and testdrove my car and saw the difference. Now they decided to swap battery packs en voila.......my car ran fine !!!!!!!
With this story I would like to say that Honda did not believe me that the battery pack was the problem, now they believe me and the parts are ordered. In may the pack will arrive, so that after 6 months I can drive my car again......................... ;)
