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.
