Re: Not able to drive. P1A15 error.

Even though you bought a new aux battery, did you ever charrge it to full? No telling how long it set on the shelf at the store. A weak aux can cause intermittent operation and faults.

Re: Suggestion on Diagnostic Car Code Reader for miev?

i use a i909 from iCarSoft on my 2012 miev; not sure if it works for the 2016 models.

There may be some phone apps which can do this using a wireless OBDII device, maybe those developers will respond to your request.

Re: Troubleshooting by replacing boards?

The first page of this thread was organized such that the entire 66 pages do not have to be read to find and fix a failure of your OBC. You just need to read the first page and you can fix it. Is that too much? On the first page is a list of people and a link to their problem, and if they fixed it, ...

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

Howdy Matheos, and welcome to the forum, sorry to hear that you had OBC issues with such expenses. For sure that is the reason for this thread, to help determine what has failed and how to repair it. There are 3 boards inside the OBC/DCDC Converter; 2 for the OBC in the upper chamber, and 1 for the ...

Re: Electric motor unit warning light (stopped charging mid-charge)

... I've learned that the 12V might be part of the problem--it is the original 12V. But the dome lights still turn on bright without the key, and the radio turns on in ACC mode, and the car is able to start, so it seems like the 12V is still functioning. Can you recommend any troubleshooting steps ...

Re: Replace CMU?

Are you seeing any dropouts on the other cells in that module? It seems that a low voltage power supply issue would affect all the cells, not just one..? i think there is a forum thread with pictures and schematics of the CMU board, i remember seeing this https://i.imgur.com/7s6JTru.jpg

Re: Quick question: Not charging after installing battery.

i think your problem is due to, or aggravated by, the low auxiliary battery voltage. An old, weak or worn out aux battery can cause a multitude of faults on EVs.

Re: Replace CMU?

Not sure that this is a common fault, but there is an IC on the board that measures the cell voltages and drives the cell balancers. There may be several cases in which this chip was found to be at fault, and it could be that replacing the chip would restore your CMU. Other folks have successfully r...
