Courtesy Lamp: Description and Operation
ILLUMINATED ENTRYThe Illuminated Entry System is available on vehicles equipped with the Remote Keyless Entry (RKE) system. The Illuminated Entry System turns ON the courtesy lamps when the remote keyless entry system is activated.
The Remote Keyless Entry Module and the Body Control Module (BCM) are used to control the system. Courtesy lamps will turn on for 30 seconds and "fade-to-OFF" over a five second period.
The Illuminated Entry System also turns ON the courtesy lamps when a door is opened. The courtesy lamps will remain ON while the door is open, then "fade-to-OFF" 30 seconds after the last door is closed.
The courtesy lamps will "fade-to-OFF" immediately when the ignition is switched to ON.
The Illuminated Entry System cannot be activated during the 30 second period after the ignition switch is turned OFF except by using the RKE transmitter. If a door is opened and closed during this 30 second period, the system will function as previously described.
The courtesy lamps will "fade-to-OFF" immediately if the RKE lock function is actuated with all the doors closed.
