1996 Cadillac Deville NO RFA Data

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.
