Hello let me help you with any of your Honda problems.
Has the IMA light come on and was your mechanic able to get any codes that may have been set? Also is this the original IMA battery module in your Insight?
NO IMA light. what is the "original IMA battery module" mean? the big battery was replace under warranty in about 2006.
Yes the battery module is the big battery. Do you know if they replaced the Battery Condition Monitor and Motor Control Module when they replaced the battery in 2006? In some high temp climates the IMA battery can be over charged and then deteriorate. They came out with updated control units for this problem which may be some of what you are experiencing.
Also did your mechanic mean to say IMA light or ABS.......I really would not see why he would need the ABS light to be on.
I do not know if that was replaced. I can try to find the paperwork and see what it says. This car lives in the Pacific Northwest so is not in a hot climate. What would that part cost? I just replaced the 02 sensor for about $1000.
Those two control modules are high dollar.....I would guess around $1000 a piece. If you live up North I would not think that would be the problem though. You may also have another IMA battery that is starting to fail intermittently.
Does the idle stop seem to work correctly and is the Assist working when needed?
Will the car keep running or am I in danger of getting stranded? About what would it cost to replace the IMA battery? The auto stop works fine but yesterday the car died while in auto stop. I have noticed no problem with the Assist.
You would be looking around $3500 to replace the IMA battery.....that is a guess though. You have to call the plant in California to get exact pricing. How many times has the car died on you while in Auto Stop?
I also found this excerpt about the gauge dropping all of a sudden.
doesn’tread the battery level directly. Instead, it calculatesthe level by continuously measuring the currentflow, voltage, and temperature.Since the IMA charge level

Since the IMA charge level
read directly, smallsensing errors can, over time, cause the gauge toread higher than the actual battery charge level.The IMA system then does a self-correction, andthe battery level gauge reading suddenly drops.When this happens, IMA assist and the Auto IdleStop function are disabled until the IMA battery isrecharged enough by normal driving. This shouldtake only a few minutes.This correction of the battery level gauge isnormal and

This correction of the battery level gauge is
mean there’s a problem. If theIMA battery develops a problem or it becomesdeteriorated, the IMA system indicator comes on.You’ll notice this self-correction taking place inthis common scenario: After having parked thevehicle with the IMA battery at least 50 percentcharged, you start and drive the vehicle a shortdistance (a block or so). The battery level gaugenow indicates zero charge, and the IMA charge/assist gauge indicates the IMA battery is charging.This is a normal characteristic caused by the IMAbattery gauge self-correction process.

It died in auto stop when the battery discharged about 3 or 4 times. Yesterday I had not battery discharge but it dies in auto stop about 3 times within a short time span. That description seems to fit what happened to my car until yesterday. So it can be a self correction? Why now after over 12 years without doing it?
That is a good question and I am not too sure how much that applies to your actual problem......it sounds like you are getting a weak IMA battery and that is what is causing all your problems. Did the tech actually hook up the scan tool to check for codes......sometimes there will be a code set even though the light is not on.
NO he did not hook it up. Told me since the light had not come on nothing would show on the computer. I checked to make sure the light shows when I start the car and it appears to be working. The mechanic I spoke to told me the car would run without the big battery but that my mileage would be less. Is that true? I am consered that it will die and I will be stranded somewhere in the middle of traffic or be waiting on the freeway for a tow.
I have been looking through the paperwork on the car and I have not found the one on the battery replacement but a mention of it in 2004, so it appears it was late 2004 when it was replaced, but I cannot see what all was done.
It will run and to an extent he is correct but without the IMA battery working properly the engine will be running on it's own with no assist. You could also have a problem in addition to the IMA circuits but we usually troubleshoot that system first since it can make all other system act up. There is also a DC-DC converter in this setup that acts as the alternator for the car. If this fails it would be just like your alternator failing and your small battery would not be properly charged. However if this was the case your battery/charging indicator would likely be on.
I would also have the small battery checked to make sure it is properly charged and that all connections are tight and clean.
I just replaced that battery within the last year as it was dead. Is it possible something with that replacement is triggering the problems I am having now? That is the only work beside oil changes that has happened in the last year.
Ok if it was replaced in 2004 it has been 8 years since replacement. Just like any other battery the IMA will discharge over time due to normal use.
I doubt replacing the small battery would have anything to do with it since that is just used for the electronics in the car.
Always worth double checking though.
So the way it is acting could just be the beginning of the end for the IMA? It does charge well and maintains a good charge until one of these events happens. Is the new thing of yesterday, dead engine at stopping with no battery discharge related, or it this a new problem. I know the car is 13 years old and will begin to have problems.
Honestly I am not sure without being able to run some diagnostic checks on it but it could very well be related to the IMA system. Like I was mentioning earlier the IMA system malfunctioning can cause various different problems in one of the Hybrid models. Unfortunately technology is much better now than it was in 2000 and we can look at our data list to check the actual battery capacity for the IMA to tell if it is losing it's state of charge. Wish that could be done for your year model Insight but you should still have it checked to see if any temporary codes are set.
I would also have him check to see if any Engine codes are stored that may lead to a potential problem from the non IMA side of the system.
Ok so your recommendation is to take it is and have them hook it up to the computer to run a diagnostic on it. About what will that cost me?
That should not cost you any more than $100 and if something is found definitively they should apply that money to the repair of the vehicle if you choose to repair it.
And yes that is what I would do next.
Ok thank you for your help. I will take it in.
It does sound like an IMA problem from your description of how things are working at the moment.
No problem at all and let me know if you need any further help in the future. Thank You for letting me assist you today!
Thank You and have a great day!
