Driver Door Power Lock Switch

The driver door lock switch is the same as the passenger door lock switches, but it is wired to the driver door switch assembly (DDSA), and, for a ground circuit, the driver door module. It works the same way as the passenger lock switches work but the switch input information is processed by the DDSA. The DDSA has two circuits that supply 5 volts to the driver door lock switch, one for a lock input, and one for a unlock input. The driver door lock switch ground circuit is provided by the driver door module. When the door lock switch is activated, voltage flows through it, thus providing the DDSA with the necessary input. The DDSA then relays the switch information to the driver door module via the power door serial data line.
