Ok that's a transfer case neutral indicator circuit malfunction code. Typically what I see with this is the encoder motor position sensor wears out by contact brushes and causes sensor to ground out. This is,usually what I see and doesn't necessarily mean that's what you have. But the position switch I believe is around $50 as opposed to most places wanting to sell you a whole encoder motor for about $400.
