code B 1048-01
I have a 2013 f150 3.5 eco boost. the parking break light stays on. I have checked all the obvious things. I am getting a B 1048-01 code It say low break fluid switch fault. I replaced the switch still have the code. If I unplug the connector at the master cylinder it alarms in the dash and says low break fluid. with it plug in it is just the light on in the dash annoying bell for a couple minutes when I put it in drive. Also the cruze does not work
would anyone have the trouble shooting plan for that code?
Thanks for the help

Hey there! I currently have the same issue with my 2013 Ford F-150. I went through the process in the image you provided, but the brake warning indicator still stays on. In the image, it tells you to "REMOVE the jumper wire. GO to N9." Could you possibly provide the link of source in the image so I can troubleshoot further? Thank you!
