Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Interior Roof Lighting
There are a number of lamps inside the passenger compartment. The lamps include four reading lamps and a general courtesy lamp.
The front left and front right reading lamps and the courtesy light are located in the same unit in the roof, just above the rear view mirror. The two rear reading lamps are located in the roof above the rear seat.
The five lamps transmit control signals to the control module. These signals allow the control module to determine the status of the lamps and switches This allows faults such as broken bulbs, open circuits or jammed switches to be detected.
The five control signals are distributed as input signals at the four inputs in the upper electronic module. The control signal for the courtesy lighting shares the same inputs as control signals for the front reading lamps. The rear reading lamps each have their own input.
Two different lighting times can be programmed using VIDA depending on the requirements of the customer.
- Short lighting time which is the time from when the door is unlocked or closed or from when the engine is switched off until the interior lighting goes out. The time can be set between 5 and 255 seconds. Normal setting is 30 seconds
- Long lighting time, which is the time from when a door is left open or from when a light is lit using a button to when the interior lighting goes out. The time can be set between 0 and 255 minutes. Normal setting is 10 minutes.
There are diagnostics for all lamps in the inner roof lighting.
