Normal Operation
The Remote Function Actuator (RFA) module controls the luggage compartment lid latch release when requested by the Intelligent Access (IA) feature. When the luggage compartment lid is closed and the exterior luggage compartment lid release switch is pressed, the RFA (Remote Function Actuator) module activates the luggage compartment external antenna, which sends out a low frequency signal. If an IA (Intelligent Access) key is within 1 m (3 ft) of the exterior of the luggage compartment, the low frequency signal activates the IA (Intelligent Access) key. When the IA (Intelligent Access) key is activated it sends a high frequency signal back to the Remote Functions Receiver (RFR) module. Once the RFR (Remote Functions Receiver) module receives the IA (Intelligent Access) key information, it sends it to the RFA (Remote Function Actuator) module. If the RFA (Remote Function Actuator) module determines that it was a programmed IA (Intelligent Access) key, it will release the luggage compartment lid latch.
- DTC B10C6:01 (Exterior Trunk Antenna: General Electrical Failure)- an on-demand DTC that sets when the RFA (Remote Function Actuator) module detects that the liftgate IA (Intelligent Access) antenna circuits are open, shorted to ground or shorted to voltage.
- DTC B113E:11 (External Boot/Trunk Release Switch: Circuit Short To Ground)- an on-demand DTC that sets when the RFA (Remote Function Actuator) module detects a short to ground on the external trunk release switch input circuit.
