Locked State: Both slide-out room locks are in the LOCKED state.
Unlocked State: Both slide-out room locks are in the UNLOCKED state.
No Shift State: Transmission inhibited from shifting gears. The Shift Inhibit relay closes when any Room IN limit
switch is not closed which indicates the respective slide-out room is in the IN state. The NO SHIFT LED indicates the
transmission cannot be shifted.

4-7.3.2 Service Mode
When the Service switch is in the “ON” position, the “Shift Inhibit” relay engages and prevents the coach transmission from
shifting gears. The Service Mode overrides the “Accessory” and the “Air System” interlock conditions required for Normal
Slide-out operation; i.e. the “Accessory LED” and “Air LED” on the Room Motion Switch Panel do not have to be lighted for
Slide-out operation. The “No Shift LED” on the Room Motion Switch Panel is lighted.
