Code #4

Unit will not drive,AC machine ,Code indicates park brake applied (lite on dash)but more in depth , I disabled switch and have full batt voltage at keyed brown/ wht wire and no voltage at green/ red wire ( at switch). This wire is pin #19 or wire #49 at master controller-which being disconnected should simulate an open and should deactivate the park brake issue but does not
Are there any other checks before condemning the master controller ?
Desperately seeking infor :)
