Driver Door Power Lock Switch

The driver door lock switch is the same as the passenger door lock switch, but it is wired to the Driver Door Switch Assembly (DDSA), and, for a ground circuit, to the driver door module. It also works the same way as the passenger lock switch works, but the switch signal input information is detected and processed by the DDSA. The DDSA has two circuits that supply 5 volts to the driver door lock switch, one for a lock signal, and one for an unlock signal. The driver door lock switch ground circuit is provided by the driver door module. When the door lock switch is activated, the normally open switch contacts are closed, the voltage flows through the switch and is detected by the DDSA. The DDSA then relays the switch information to the driver door module via the class 2 serial data circuit.
