Rear Door Power Lock Switches

In order to receive an input from its associated door lock switch, the left rear door module and the right rear door module supply battery positive voltage and ground to their associated switch. As a safety feature, the rear door lock switches do not have circuits for the unlock function. When one of these switches is activated for a lock function, voltage flows through the switch, providing the module with the necessary input.
