Whats up everybody, i'm having a bit of a problem on my 05 G35x with 185k. Couple of months ago, my abs, vdc, and slip lights came on and the abs pump would continue to run after that. Well soon after I got all my rotors and pads changed and I never had that problem again. Well now two months later, the problem is back only this time the abs pump turns off after a while or by me shutting down the car. Do I need a new ABS pump or a new Relay?

 

Maybe it's the relay, bench test it 50 times.

 

Okay because when I had it at the shop it had the following codes: C1110(Controller Failure), P1574(ASCD VHL SPD SEN), P1212(TCS/CIRC), and U1001(CAN COMM CIRCUIT).

 

I suspect that C1110, and U1001 and P1212 problems are because you have a bad vehicle battery or corroded lugs, have the battery load bank tested at a shop to make sure it's actually good, use a wire brush to clean ALL THE CONNECTION POINTS NOT JUST THE TERMINALS OF THE BATTERY! Follow the battery cable, unbolt everything, clean everything, there are 3 connections on the positive side right at the fusible link alone.

P1574 might be related but it probably just a bad wheel sensor.

I'm going to guess you didn't take it to Nissan because they would have told you exactly what the problem was instead of just giving you a bunch of DTC's.
