SUN SENSOR (ELECTRONIC CLIMATE CONTROL ONLY)
The sun sensor consists of a photo diode powered from the central electronic module (CEM). The conductivity of the diode depends on the amount of light to which it is exposed.
The diode is located under a diffusing lens which reduces the sensitivity of the photo diode to the angle of the light hitting it. Increased sun intensity reduces the voltage over the photodiode.
The control module measures the voltage across the photo diode and converts the voltage to information which is then transmitted to the climate control module (CCM) via the controller area network (CAN).
The sun sensor is located in the middle of the dashboard by the windshield.
There are diagnostics for the sun sensor.

The blind spot information system (BLIS) is an auxiliary system designed to help the vehicle's driver when moving sideways. The blind spot information system (BLIS) consists of two cameras integrated in the external rear view mirrors and two LEDs located in the panel at the front of the inside of the respective windows.
The central electronic module (CEM) communicates with the left camera module (LCM) and the right camera module (RCM) via serial communication.
The blind spot information system (BLIS) is always activated automatically when the ignition is switched on, but it is possible to deactivate and activate the blind spot information system (BLIS) using one of the switches on the dashboard environment panel on the climate control module (CCM). A signal is then transmitted via the central electronic module (CEM) to the left camera module (LCM) and the right camera module (RCM) with a request to deactivate or activate the blind spot information system (BLIS).
When reverse gear is engaged, the blind spot information system (BLIS) is deactivated.
The blind spot information system (BLIS) can be diagnosed.
Using this function, the status or value of parameters can be read off. The status/value is presented digitally.
For further information about the different parameters, see: DESCRIPTION OF PARAMETERS
This function can be used to activate components and functions which affect the outputs of the central electronic module (CEM).

This function allows programmed data to be read off or data such as customer parameters to be programmed in.
Note. If possible, all data must be read out from the control module before replacement. After replacement the relevant data must be programmed into the new control module. The data must be read off before the control module is replaced. This is so that the same information can be programmed in to the new control module.
