WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
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.
