There is a diagram showing the expected diode voltage drop measurements at the solder joints with all the fastons tabs disconnected to remove the external circuit paths: https://myimiev.com/forum/viewtopic.php?p=40562#p40562 Thank you. I have bought a cheap multi-meter with diode function, fully di...

What DTC does it throw now? i hope it is a different code. Unfortunately, it is the same single code: P1A12 - OBC abnormal stop In post #2 on page 1 is a section with a schematic of the waffle plate soldered under the power board. Also is a link to the diode drops that can be measured at those 72 s...

Did you ever check the diode drops in the waffle plate? That was recommended as the first thing to check on the previous page. How can I check that ? Do I have to de-solder all those (many) connection points -- two rows on each side to remove the plate from the bottom board ? The diodes are in betw...

I put it back together, also replaced the dead fuse in MCU and burned out capacitor: https://i.imgur.com/PvtSOLp.png Now, there is some improvement: - no red 12V battery charge indicator error light - no yellow drive unit error light when I turn it on However, it is still not charging. The code read...

Operation pin-swap completed. I also made (an ugly) solder-blob to connect 49-50 on the board if they are both ground to share.



Now it is getting dark, so I wait for tomorrow morning to put the board back into the car and test.

Correction, the F102 is not blown, checked with an ohm meter and it shows near-zero resistance. The fuse inside the MCU is blown, but I got the replacement for that already. The connector I got to replace the NC1 is not an exact match (different plastic cover shape, not compatible with the black con...

Thanks for the great info guys! The mystery of the desoldering is interesting indeed. My guess is that it was never soldered in the first place -- sloppy manufacturing job ? I can push the connector back onto the 2 metal clips at the end, then it is held firmly in place with the pins making contact,...

Taken apart the OBC,. Looks like I got a fried capacitor: https://photos.app.goo.gl/pzE6NvqwundQ5w489 hmmm, need to figure out how to post image, google photo link does not seem to work... It is the top blue one in the doghouse surrounded by the black conformal coating on this picture (this is not m...

Thanks for the explanation of those codes.
I have replaced the 12V battery and put in a fully charged new one.
Now, I got 2 new codes:

P0A09 DCDC converter fail
P1A12 On board charger abnormal stop

Hi All, I have a 2011 i-Miev that stopped charging a couple of days ago. Tried to make an appointment at the local dealer, the first available time is in 2 weeks, so I got an iCarsoft reader to try to figure out what is the problem. When I plugin the AC charger, the car shows the icon for the plugin...
