DBmandrake: Thank you for lots of good additional info. In your case with the failed 12v battery, If battery plates get aged and coverted in sulfate, it will loose capacity, but charging current is reduced. But, The other failure mode of these batteries is when plates collapse and short. When...

KIEV: I am tending to give more weight to your theory that majority of OBC Failures are being caused by a sick 12v aux battery. At first, I thought these failures were due to mains power surges, but now I see more evidence towards the aux battery being the lead contributor to these failures...

DBMandrake: Thank you for pointing out that the OBC has to have AC active to be able to see it on canbus. That has stumped me for a while. I do have some documentation that does show there are more than one CANBUS in a IMIEV. I'll start posting some pictures to show this. On the schematics...

ChristofER: I bought a chinease clone of a MUT III diagnostic tool, and I can use it to scan all the DTCs like a real MUT III, but one of the weird things is that when I go to the menu section to look at things like EV-ECU, CMU, BMU and OBC hardware and firmware revisions, it cannot read...

MIKEDUFFY: Thanks for clarifying that, sorry I did not mean to add misinfo, so the charger may also been faulty. I remember teilling you about the fuse earlier. I think once they swapped chargers they then came across the fact they also had the blown 20amp fuse in the MCU. Or they replaced...

There have been three more OBC failures in the last few months. One was from MikeDufty that was mentioned earlier. He took car to dealership, they first swapped out charger, then found that was not the fault, and then finally came back saying there was a wiring fault. The second OBC Failure was...

ChristophER: So far I have come across first of year 2010 IMIEV and Mid year / end of year 2010 IMIEV. The first of year 2010 used a set of 3 pcbs instead of a set of 2 pcb's for the ac charging section. It appears that from Mid 2010 up to 2012 all pcbs look same and can plug together, but the...

Hi Target: There are two connectors coming out of the OBC Towards the rear bumper. One connector has the Active, Neutral, and Ground lines from the charging port conntector. The other connector is called E-03 and has all the signal and supply lines from all over the car going into the charger...

footswitch: The potting in the "doghouse" is a rubbery type substance, while the potting on the waffle board is a hard solid resin type potting. If you are replacing the potting around the resistors, caps, and relay in the doghouse, I would still stick with a rubbery type, rather than the hard...

REDCANE: If your fault is the fuses inside the battery pack, here is some info: There are four fuses inside the main battery pack, that can be accessed/replaced, without having to remove the battery pack from the car. There is a plastic cover, that covers the whole under belly of the...

ChristophER: Interesting find on the data sheet for the resistor. I read this a couple of times, and it sounds like they take the "pellet" of a 10 watt rated resistor and add the thermal link, and the addition of the link causes the overall rating of the device to be de-rated to down to 5...

MIKEDUFFY: I just took the EV-ECU that came from Chris's IMIEV and swapped it with the one in the Wrecked IMIEV Testbed. It started in READY No problems, then took it for a short drive, then put in on charge just to make sure no errors came up while in charge mode. All worked great, never even...

mikeduffy: It sounds like you had the charger replaced under warranty, but are are still having issues at the dealership? I sent you a PM, and I might have spare parts that could be used to trouble shoot EV-ECU issue. Is it possible for you to get your hand on / keep the original broken...

Mikeduffy: Just came across this thread and that your car is still at the dealer. It appears that on the report when you first took your car to the dealer, one of the items listed is re-programming the EV-ECU. Now it sounds like they want to replace the EV-ECU. I think the first fault was...

Hi Kiev , Coulomb: I might get a chance to work on another IMIEV Charger. I got a call last week that another member of the AEVA (Australian EV Association) has a IMIEV that is causing problems when plugging into the Bollards at the University of WA to charge, and so far it has caused two of...
