The remote receiver module (RRX) is on the top of the driver information module (DIM).

The remote receiver module (RRX) is connected to the central electronic module (CEM) via serial communication (LIN). The remote receiver module (RRX) receives the signals transmitted from the remote control and forwards them to the central electronic module (CEM). When a key is in the ignition switch, the Central electronic module (CEM) ignores all messages from the Remote Receiver Module (RRX). This prevents the central locking system from unlocking if a button on the remote control is unintentionally pressed in.

The remote receiver module (RRX) checks for a signal from a remote control 4 times per second.

The receiver is powered by the central electronic module (CEM) and grounded in the right-hand A-post.
