Default Vdc abs brake slip light on

So I've been working on this for awhile and I can't solve it. I've invested into one of the icarsoft computers and ran a diagnostic on my 07 350z and I'm getting C1114 for my abs.so I tested the relay for the abs. I disconnected the battery, took off the 3 plugs and took the housing apart to get to the repalys. I put a 9V battery to the prongs and I can hear and feel the relays opening and closing. I assembled the relay house back together and plugged it back in to see if there's any volts getting into the wire. I tested the middle plug first on the relay with the car on with a test light . Sure enough I can here the relays opening and closing and the pump even turned on. Than I tested the other two plugs with the test light and there's power on one of them but not the other. When I used a volt meter I got volts on 2 of 3 of the plugs. Now I found this odd. So I figure since the middle plug activates the pump as it did in the beginning, maybe if I use the test light to activate the pump again I'll see a volt reading on the plug that had no power. Sure enough that worked, so now I feel it's safe to assume that's a signal wire. I used the test light to see power and the relay opened and the pump turned on and now I seen voltage comming through, it read 9V . However. The light are still on in the dash and the c1114 Code won't go away. I've erased it and topped my fluids off and checks ALL the fuses. I've replaced the wheel speed sensors even, Somebody help. I'm not sure if the abs control module went out or what's going on now. I hate driving this thing in the rain, anxiety like a mother F
