Driver Door Power Lock Switch

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

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, the driver door module. It also works the same way as the passenger lock switch works, but the switch input information is detected and processed by the DDSA and less voltage is used for the switch signals. 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, the voltage that flows through it is detected by the DDSA. The DDSA then relays the switch information to the driver door module via the power door serial data line.
