Re: VDC stuck on, re-gen also suffering

These just mean you need to add more air to your tires, they are under inflated:

C1704 0008 BCM Low Pressure FL WT-26
C1705 0008 BCM Low Pressure FR WT-26
C1706 0008 BCM Low Pressure RR WT-26
C1707 0008 BCM Low Pressure RL WT-26


For the rest, I would review these manual for some ideas:

  • http://www.nicoclub.com/manuals/Leaf/2014%20Leaf/sec.pdf (B2555 0009 BCM Stop Lamp Circuit SEC-69)
  • http://www.nicoclub.com/manuals/Leaf/2014%20Leaf/br.pdf (C1A67 0109 BRAKE Stop Lamp Switch BR-98)
  • http://www.nicoclub.com/manuals/Leaf/2014%20Leaf/br.pdf (C1A70 0109 BRAKE Brake Control System BR-160)
  • http://www.nicoclub.com/manuals/Leaf/2014%20Leaf/brc.pdf (for the other DTCs that show "BRC" in the description)

Look also at BRC-10 thru BRC-12, as there is a diagram showing the location of relevant parts. In particular, the location of the VCM, wheel sensors, control unit, etc.

FYI, all the service repair manuals seem to be available here:

Nice!

As a first step, I would check that none of the cables/connectors have come loose on the key components. As mentioned earlier by another poster, it would be a good idea to check the voltage of your 12V battery as low voltage can cause a bunch of weird issues. If you have a battery charger, then trickle charge the 12V battery, clear the DTCs (using LeafSpy), then see if they reappear with the 12V battery now charged fully.

May have to disconnect 12V battery - terminal for 5 minutes ( better : charge it while disconnected to over 12.6V using a standard 12V charger) then reinstall and clear dtc's.
At least that will fully eliminate that possibility.
