Description & Operation

WARNING: This page is about a different car, the 1996 Mercedes-Benz C280 and 1996 Mercedes-Benz C220. However, it is still accessible from the selected car via links, so may be relevant.

Keyless entry system is an infrared controlled system consisting of a transmitter, Remote Central Locking (RCL) control module, Drive Authorization System (DAS) control module, 3 receivers and related wiring. Vehicle can be locked and unlocked using remote control. Windows and sun roof can be also closed using remote control.

The keyless entry system is connected to engine control module using Control Area Network (CAN) data lines. The RCL control module and engine control module are coded together. This identification code can not be erased, thus swapping control modules for trouble shooting can not be done unless a matched pair of control modules are used.

To unlock vehicle, point transmitter at one of the 3 receivers and press transmitter button until Green light on receiver illuminates. To lock vehicle, point transmitter at one of the 3 receivers and press transmitter button until Red light on receivers illuminates. To lock vehicle and close windows and sun roof, press and hold transmitter button until vehicle locks and all windows and sun roof are completely closed.
