RFA Module

The RFA module is responsible for obtaining the passive key data and keyless entry lock/unlock requests. It uses the keyless entry antennas and the Radio Frequency (RF) receiver to receive the passive key data. The RFA module receives direct input from the Radio Frequency (RF) receiver (over a single circuit network), the keyless entry antennas and the lock/unlock sensors. The RFA module communicates the passive key and request data to the BCM over the Medium Speed Controller Area Network.

If the RFA module is replaced, at least two keys must be programmed to it and a parameter reset performed with the BCM to enable the PATS.
