Reset your IMA system to get the gauge to show normal ranges, then we'll see how bad the battery actually is. You should get at least a minute of assist from full.The battery on my 2000 Insight- 90k- never loses more than 2 bars from full charge. Assist is VERY limited- 30 seconds at best. Is this a bad battery, controller, or? This must have been addressed before, but I cannot find the thread.
Hi Mike,... Also, the BCM always charge the battery on a steady drive to warmup the pack....
When the Car is in Assist, how many bars are lit on the Assist gauge?The battery on my 2000 Insight- 90k- never loses more than 2 bars from full charge. Assist is VERY limited- 30 seconds at best. Is this a bad battery, controller, or? This must have been addressed before, but I cannot find the thread.
If the IPU was overheating it would throw an IMA light.Driving home from work, I lost assist, but regen continued to work. When I pulled off at the exit auto stop and auto start worked correctly. My Battery state showed that it was full. I then drove with no assist and a full battery until I reached my destination. When I returned to my car and started it again, all was back to normal for about 1 mile, then I lost assist again. At a stoplight further down the road, I thought I would do an experiment, I turned the key to the off position, and then back on. Assist was again temporarily restored. I did this several more times on my way home, with the same results. It seems like something must be outta whack. Perhaps the electric motor is overheating?
Not all error codes light the CEL or IMA. You need to scan your car to see what the car thinks is wrong. Is there an Autozone near you? You can use their tester for free (except in California).IMA reset did not work. Some other clues that may or may not be related are that I had a check engine light a couple of weeks ago that stayed on until the next fill up, I thought that it was just a loose gas cap. My loss of assist started yesterday after I filled up on a new tank of gas. I have no check engine light. I found another thread where a gentleman from canada was having similar symptoms, and it was ultimately resolved with a LAF sensor. I need to do more research before I try that.
The diagnostic tests say to check your fuel pressure first to see if it is too low or high. Otherwise the culprit is the LAF sensor or the evap canister or the injectors.So I had it code scanned, and they came up with a PO171 system too lean. They said it might be an oxygen sensor. Afterwards, on my way home from the Advanced Autoparts, my check engine light finally came on.
