Principles of Operation

The Remote Function Actuator (RFA) module is only equipped when the vehicle has the Intelligent Access (IA) feature. On vehicles equipped with this option, the RFA  controls mostly the IA  and related entry/anti-theft systems (such as the power door locks and the liftgate release). The RFA  module communicates on the Medium Speed Controller Area Network (MS-CAN). The RFA  module controls the following functions:

• Intelligent Access (IA) feature
• Keyless entry keypad illumination
• Liftgate release
• Passive Anti-Theft System (PATS)
• Power door locks
• Remote Keyless Entry (RKE) system
