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

Howdy Mark and Welcome, Sorry to hear you are having problems with the OBC. It sounds like you have had a failure on both the AC input side, and on the HVDC output side, which is not typical. It may be that more details of your failure would help determine what happened--usually these two don't happ...

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

Howdy Ferenc, and Welcome to the forum. First thing: What is the age and condition of the 12V Aux battery in your car? Is it old, weak or worn out, or the original (7-year old), then replace it and try again. It doesn't hurt to inspect and clean the contacts in the car port and the EVSE handle, also...

Re: Battery Replacement - Lessons Learned

Sorry to hear Suzanne. Where are you located, maybe someone close by can use one of the phone apps (Canion or Hobdrive or the other one) to do an independent check on whether your pack is normal or defective and you are entitled to a new pack under warranty. Or you could buy the dongle for $50 bucks...

Re: No READY. P1A15 error. Condenser charge timeout.

Yes it does go to the bottom of the lower right corner of Lic's photo, to Connector CN4, labelled "VDC". The red and blue wires are from the (+) side of the pack and route to pins 1 and 2; the white wire is from the (-) side of the pack and routes to pin 5. CN4p1 then routes to CN5p1, labe...

Re: Heat Damaged Charger Plug

Howdy Icarus, i assume that the dealer would let you test drive the car. When you turn on the key the dashboard will come alive and you can read the gauges. So check the "fuel" gauge to see how full it is and count how many bars are showing, Full is 16 bars. Half is 8 bars. You probably wo...

Re: Onboard Charger (OBC) Failure - P1AFE

Those components are on the bottom board in the AC Input path. One of those ceramic resistors also has an internal fuse, may need to check it also. i think a few folks have had those parts fail, there my be some discussion about how they made and tested the repairs. Did he replace those parts from a...

Re: my miev do not see the traction battery

The EV-ECU is the main controller of the car, and it controls all the functions related to the traction battery. A good strong 12V aux battery is needed, since the EVECU drives many relays and contactors after the key is turned ON and to START, in going to READY. It sounds like the relays are not be...

First time we have seen or heard of that failure, but hopefully an easy repair.

Re: Onboard Charger (OBC) Failure - P1AFE

That is a lightning surge arrestor on the AC input side.

Which resisitor and capacitor were damaged, can you post a picture or give us the reference designators, e.g. R21 or C117.

Re: CMU board notes, eprom, cell numbering

... I find it strange that the lower voltage regulator has a voltage divider going to pin 1, and the upper one doesn't. Worth a double check? i double checked and the threshold adjustment feature for pin 1 is not being used for the HV 5V regulator, it's tied to ground which is done to use the on-bo...
