Remote Control Door Lock Receiver (RCDLR) Module
The Remote Control Door Lock Receiver (RCDLR) module is the door lock master device. This means the RCDLR has final control over whether or not doors will lock or unlock.When the passenger door lock switch is activated, the switch signal is received by the passenger door module and then sent, via the power door serial data line, to the driver door module.
When the driver door lock switch is activated, the signal is received first by the Driver Door Switch Assembly (DDSA), and then sent, via the power door serial data line, to the Driver Door Module (DDM). Once the driver door module (DDM) has received lock switch information from either door lock switch, it sends the information on to the RCDLR by the class 2 serial data line.
The RCDLR will not allow the doors to be locked when the key is in the ignition and the drivers door is open. The drivers door has a dome/jamb switch which closes when the door is opened. The DDM reports the status of the driver door dome/jamb switch to the RCDLR via the Class 2 serial data line.
