Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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, one CANB...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 anything fr...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 the fuse ...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 with...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 very ...

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. In yo...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 ...

Re: my Miev will not charge

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 car/battery pac...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

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 ...

Re: my Miev will not charge

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 came ...
