Howdy,
I have had this problem with my sequoia recently where I get only a P0504 code and the emergency brake light and the VSC light comes on did some research and figured that it was a bad brake pedal switch replaced it with an OEM switch and the lights are still illuminated however I am no longer getting a code I tried to do an ecu reset via leaving the battery unhooked for about 10 minutes and let the system de-energize lights would go away then come right back after ten seconds and after that I tested the ECU for the proper voltage tested within spec now I am a little lost
any insights or diag tips would be appreciated
Thank you for much for reading and have a nice day
