Brake Replacement on ‘19 Causing Warning Lights

717 Views 17 Replies 6 Participants Last post by  RGR
Hey all!

Just replaced pads and rotors on all 4 corners on our 2019 Ascent today. While the job went relatively smoothly, I’m now left with the following warning lights on in the vehicle : ABS, Traction Control, and BRAKE. When driving it also flashes PARK.

I am able to drive the vehicle with no issues aside from the Christmas tree on the dash. I bed the brakes in properly and then parked it due to said lights.

I followed the advice on previous threads and used an INNOVA 5510 diagnostics tool to put the EPB in and out of maintenance mode for this job. The tool now shows a B0400 error code in the ABS/VDC System, but I have yet to find any documentation as to what that is.

Any help here would be greatly appreciated!

That’s not a 100k pad… that’s a 100k pad backing 😳

What pads did you put on it? If they’re oem there’s no properly bedding them, it’s just driving without hard braking for 1000mi.

Did you check if the parking brake works, despite the lights/ warnings?
