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 module activates the luggage compartment external antenna, which sends out a low frequency signal. If an IA key is within 1 m (3 ft) of the exterior of the luggage compartment, the low frequency signal activates the IA key. When the IA key is activated it sends a high frequency signal back to the Remote Functions Receiver (RFR) module. Once the RFR module receives the IA key information, it sends it to the RFA module. If the RFA module determines that it was a programmed IA 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 module detects that the liftgate IA antenna circuits are open, shorted to ground or shorted to voltage.
• DTC B10C6:13 (Exterior Trunk Antenna: Circuit Open) - an on-demand DTC that sets when the RFA module detects that the luggage compartment external antenna resistance is out of range.
• DTC B113E:11 (External Boot/Trunk Release Switch: Circuit Short To Ground) - an on-demand DTC that sets when the RFA module detects a short to ground on the external trunk release switch input circuit.

This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• Luggage compartment IA antenna
• Exterior luggage compartment lid release switch
• IA key
• RFR module
• RFA module
