The RFA module receives a power liftgate activation command (double press) from the Remote Keyless Entry (RKE) transmitter. The RFA module sends a signal over the MS-CAN to the LTM . The signal transmitted between the RFA module and the LTM is not specific to the open or close operation. The LTM determines which operation to carry out depending on the liftgate position when the signal is received.
