"The exterior lighting is controlled by the CJB (central junction box). The CJB controls the following vehicle functions:
Control and monitoring of exterior lamps including turn signal indicators and hazard warning functionality
Communication and control and monitoring of trailer lighting via the trailer module
Monitoring and evaluation of check control inputs from other system control modules and output of applicable
messages in the instrument cluster message center.
The CJB is connected to the medium and high speed CAN (controller area network) bus. The CJB contains a
microprocessor which performs the control, monitoring and evaluation functions.
A combined rain/light sensor is fitted which controls the automatic wiper operation and the automatic lighting
function.
An Auto High Beam system can also be fitted which automatically controls the high beam headlamps.

The exterior lighting system comprises the following exterior lamps:
Front and rear side lamps
License plate lamps
Side marker lamps (if fitted)
Front and rear turn signal indicator lamps
Turn signal indicators side repeater lamps

There is also a headlight leveling control module that is in the engine compartment on the driver's side (LHD).
