Check the comfort fuse in the trunk compartment fuse block. Then you will need to remove the rear seat back to access the RFA module. The RFA module is a small black box, should have a four wire connector. Two wires are data communications, and there is a power(from comfort fuse) and ground, they are pins a and c. Orange should have 12 volts when a voltmeter is placed on it to ground, and should have 12 volts when A and C are bridged with a voltmeter. If it does, then you either have a faulty module, or fault in your communication system.
