Claim Text:
1. A method for selectively bypassing a disengagement system for a differential lock in a vehicle having a selectively lockable differential, the differential lock disengageable using a control valve in communication with the differential lock, the method comprising the steps of: a. providing a bypass valve moveable between first and second positions; b. positioning the bypass valve between the control valve and the differential lock; c. setting the bypass valve in the first position, thereby allowing unimpeded communication between the control valve and the differential lock; and d. selectively actuating the bypass valve to move the bypass valve to the second position, thereby blocking communication between the control valve and the differential lock and preventing disengagement of the differential lock; wherein the step of selectively actuating the bypass valve to move the bypass valve to the second position is achieved by introduction of working gas pressure to an actuator of the bypass valve.
