Remote Receiver Module (RRX) is located up at the headlining, to the left of the front lighting panel.

Remote Receiver Module (RRX) receives signals sent from the remote control and transmits them on to Central electronic module (CEM) via serial communication (ISO).

When a key is in the ignition the Central electronic module (CEM) ignores all messages that come from the Remote Receiver Module (RRX). This is so that, e. g., the central locking system will not be locked if a button on the remote control is pushed accidentally.

The remote receiver checks for a signal from a remote control 4 times a second.

Remote Receiver Module (RRX) is supplied with voltage directly via 30-feed and is grounded in the A-pillar.
