Interior Lighting

The interior lighting system consists of:
^ front interior lamp with integral map reading lamp rear interior lamp (if equipped)
^ vanity mirror lamps (if equipped) interior door handle illumination
^ exterior lock cylinder illumination door courtesy lamps footwell courtesy lamps
^ engine compartment lamp
^ luggage compartment lamp

The interior lighting system can be operated by a three position switch which gives:
^ courtesy lamps on
^ courtesy lamps off
^ courtesy lamps on when door open with delay

If the courtesy lamps are set to delay, as soon as the ignition key is turned to start the engine the lights will go out.

This function as all other timed functions is controlled by the Central Timer Module (CTM). This module controls a number of independent systems by monitoring and controlling inputs and outputs.

When an exterior door handle is lifted the CTM receives an input from a switch mounted to either front door. This input triggers the courtesy lamp function, which switches the courtesy lamp relay to switch the courtesy lamps on. The CTM will allow a 12 second period to pass before extinguishing the lights. This timer function is reset if any of the inputs are reactivated during this period.

The courtesy lamp delay function can also be triggered by opening any of the doors. The door entry switch supplies the input to trigger the courtesy lamp function.
