2012 Leaf Charging Problem

Thu Aug 22, 2019 5:12 am

65,000 miles. Plug in either a level 1 or 2 charger. Blue lights come on for a couple seconds and clunk, everything shuts off. Installed new 12 volt battery. No help. Connector seems to be o.k. but hard to tell. Any ideas? Thank You.

Sounds like a charge timer is set. Plug the car in and try the override the timer button.

If you can post a private YouTube video, and then link to that here, that would help tremendously. In particular, show us what's happening with the three blue lights on the dash below the windshield.

Also, see this post RE the charge timer possibility:

Tried the timer charge button to left of steering column inside vehicle. Middle blue light beneath windshield came on and shut off after a few seconds. Thus, still would not go into charge cycle.

That is the timer override button. Did you try plugging in and charging while the blue light was on?
If not, it didn’t prove anything.
If yes, and it wouldn’t charge, the problem is something else.

Do you have a multimeter and some basic electrical knowledge?

Yes, I plugged level 2 charge cable in while middle blue light was on. I have a Fluke multimeter and know how to use it. Found a U-Tube video on what readings to expect on the car level 2 charge connector. Will try that.

The readings on the car charge connector were 4.3 volts between ground and the prox pin. Infinite resistance between pilot pin and ground in either direction. Would indicate an open diode or some other failure in the OBC. Doubt that a new diode in the pilot line will fix it but will try it anyway. Could also be the cable off the car charge plug but highly unlikely.

Did you mean 4.3 Ohms?

No. DC voltage is read between ground and the proximity pin. Resistance is read between ground and the pilot pin. My reading was 4.3 volts DC between the ground and the proximity pin.

Would a problem with the cable from the cars charge connector to the On Board Charger show up as a trouble code on a OBD 2 reader and LeaSpy? I do not own a OBD 2 reader but will get one if it will check that cable.

Sorry, didn’t read your post carefully.

The results do indicate an open diode. I think someone here replaced the surface mount diode on the charger’s circuit board. There may have been a photo.

I don’t know if any DTCs would be set.
