    There is a known issue with the Ram Power Wagon locking differential system where the electronic locking differential wiring harness will fault one of three ways. The first being that the wiring harness is two short so when the rear axle articulates there isn't enough slack therefore causing the plug in the diff housing to fail. The second is that sensor inside the housing faults due to gear oil build up on the sensor. Finally the third if the locker wiring inside the housing wears out causes the locker to fault. Any of these three issues causes a "Service Axle Locker System" and prevents the front and rear lockers to be used indefinitely. This can cause the truck to become stuck during off pavement driving.
