US 11,440,536 B2 · Wireless device for disabling a differential in an all wheel drive vehicle

Abstract

For use in all wheel drive vehicles with a rear electronic differential, a device containing a switch for making and breaking an electrical connection in a ground line of a differential harness. When the circuit is broken and the rear electronic differential is not powered, the rear electronic differential does not power the rear axles. A wireless remote control has buttons that when pressed send a wireless signal to a receiver connected to the switch. When the first button in the remote control is pressed, the switch breaks the connection in the ground line. When the second button in the remote control is pressed, the switch completes the connection in the ground line.
