Bulletin No.: 63-90-11
Date: August, 1996
INFORMATION
Subject:
Synchronizing The Remote Function Actuator (RFA) Transmitter
Models:
1996-97 Cadillac Concours, DeVille, Eldorado, Seville
The Remote Function Actuator (RFA) systems that CLCD began using in 1996 have incorporated "Rolling Code" technology. "Rolling Code" offers a new level of security for the RFA system that was not available in pre-1996 vehicles. This new level of security prevents anyone from recording the message being sent from the transmitter to the receiver and playing it back to gain entry to a vehicle.
"Rolling Code" refers to the way the information is being sent out by the RFA transmitters and accepted by the receivers. The transmitted signal is scrambled in a different order upon every RFA transmission. The transmitter and receiver keep track of the appropriate order of the transmitted information. When the signal being sent by the transmitter is not in the order that the receiver is expecting, the transmission is deemed invalid and no operation is performed. This occurs when the receiver and transmitter are "OUT OF SYNCHRONIZATION".
When the transmitters are out of synchronization, look for the following symptoms:
RFA-C: None of the buttons will appear to activate any functions on the vehicle.
Causes for loss of "Synchronization"
^ 512 button presses out of range of vehicle for RFA-C
^ Replacing the transmitter battery + 10 button presses out of range of vehicle
^ Performing the resynchronization procedure out of range of the vehicle
To determine if a transmitter is out of synchronization, refer to "Resynchronizing Transmitters" in Section 9K of the Service Manual or perform the following procedure:
^ Press and hold trunk button and, within one second, press and hold the lock button.
^ Continue to hold both buttons for approximately 7 seconds.
^ If the transmitter is out of synchronization, it will now function properly.
The customer should be made aware of this condition and directed to review the resynchronization procedure in the Owner's Manual.
Warranty Information
This procedure should not be charged to warranty.
