DTC Error Code Help

Fri Feb 16, 2018 5:10 pm

So I had an issue yesterday where I plugged into a public Volta charger and the charger wasn't working, ok I reported it and after work moved on. The problem I had was my car still wouldn't charger at a different charger.

So, I opened up Leaf Spy and sure enough there was a DTC on the charger, I don't have it in front of me, but I have had that error once before and it was caused by a faulty EVSE, so I cleared the error and the car then would charge without issue.

Well, I checked in the Leaf Spy app this morning and I have an error U1000 0008 BCM CAN Comm Circuit, this error also existed last night, but I figured it was simply related and cleared it as well. The car appears to be running without any issues, but I can't seem to find out what this error means. Doing a search on google and even just on here returns a whole lot of nothing specific.

Is this simply one of those ignorable errors? I mean everything seems to run fine, doesn't seem to affect range, no extra lights are being lit up on the dashboard, so I have no clue.

BCM stands for Body Control Module so there appears to be CAN Bus communication issue(s) with the BCM. I don't know if that particular error code is serious.

Here are online tech manuals that give the DTCs and repair procedures for Nissan techs:

In your case, the BCS manual is relevant - see page 77: ... AF/BCS.pdf

Looks like it relates to the CAN bus, perhaps your OBD2 dongle caused a temporary issue on the CAN bus? I always plug mine in with the car powered off, then I typically use it with the LEAF in AUX/RADIO mode. Probably completely unnecessary, but I'm a little paranoid that the dongle might screw something up with the CAN bus.
