2004 Tundra VSC TRAC + ABS Light + Audible Alarm Problem

Hi all,

I'm been searching around the forums and scouring the internet to do some research on this problem that came up on my 2004 Tundra Double Cab 2WD. The VSC Trac, ABS, Parking Brake light (even with the parking brakes down) are illuminated, along with an audible alarm noise.

I attached a photo of the dash, and a video of the master cylinder + abs system where you can hear the audible alarm.

There is no CEL, thus no CEL codes can be read.
I used the paper clip method to determine the ABS and VSC codes, which are below

ABS Code 56 -> C1256 / Low accumulator pressure (not sure if this is correct though https://www.purefjcruiser.com/docs/.../Vehicle Stability Control System/0280030.pdf)
VSC Code 43 -> C1223/43 Abs System Control Malfunction (https://www.tundras.com/threads/reading-abs-vsc-codes-without-a-scan-tool-2nd-gen-and-more.62732/)

The problem seems to be similar to this: https://www.youtube.com/watch?v=m4_qv9bZfYY&t=80s

I'm convinced I'll have to either replace the brake master cylinder, which is unfortunately pretty expensive unless I find something from the junk yard, or I replace a specific part. What I don't understand is that the audible noise is something I don't or very rarely see in conjunction with the ABS, VSC Trac problem. Has anyone dealt with this before?

No service was done near the time of this problem, and the car is completely stock.

Thanks in advance.

 

Stoked about the 60K miles for a 2004. Brake guys here will have you fixed in no time !

 

VSC on an '04?
