RFA Module

The RFA  module performs the initial search for a programmed key. The RFA  module sends a message over the MS-CAN  to the BCM  indicating whether or not a programmed key is detected. If no programmed key is detected, the BCM  activates the PATS  transceiver in an attempt to detect a programmed key in the back location. For additional PATS  information,

Refer to: PASSIVE ANTI-THEFT SYSTEM (PATS) - SYSTEM OPERATION AND COMPONENT DESCRIPTION .

The RFA  module does not require PMI  when replaced.
