Interior Lighting
The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module (CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when either the dome lamp switch is turned on or a door is opened. The courtesy lamps will fade to off immediately when all doors are closed and the ignition is in the RUN or ACCY position.
The illuminated entry feature operates under the following conditions:
- RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned on
Once activated, the illuminated entry will "fade to off" after 3 to 5 seconds under the following conditions: All doors are closed and:
- RKE lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will reset timer. Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps. When an unlock button of the RKE is pressed, the cargo lights will turn on for 30 seconds, similar to the illuminated entry feature.
The Interior lamp defeat feature will not allow any interior lamp to be turned on. This is accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps and cargo lights due to the following.
Leaving a door open, dome lamp switch on, reading/vanity lamp switch on or glove box door open for more than 15 minutes while the ignition is off.
