Default trac light 19

so i bled the system with two small bottles of brake fluid. It was good for a day, but than the next morning when i was idling the car the light came on again. Now the trac light comes on not from pressing the brakes 10 times, but when i hit a certain speed around 50 km/ph. Flushed a litre of brake fluid down today, same thing. Diagnostic's said the same code again, code 19. does anyone know whats going on here?

Just curious if anyone has input in regards to a possible solution or route to take in order to tackle this issue? I do get trac code 19 consistently, however, there are days when the light does no come on whatsoever. It's a weird occurence. Help?...HELP! lol...

19 - TRAC motor ON and OFF operation is higher than a predetermined number of times (accumulator pressure leakage)

Do you have fluid leaking, enough to where it is losing pressure? Vacuum leak?

The brake and other fluid levels are consistent, not high nor low, so it's very unusual...

I had the same problem and cured it by replacing the nitrogen accumulator,
