Functions [2 of 4]

Daytime running lights (from structure week 201044, option)




Daytime running lights (10/56-57) are activated via an extra "auto-position" in Light switch module (LSM)(3/111). Daytime running lights can also, on certain markets, be activated via position 0 and P (parking lights).
When "auto-position" is selected in Light switch module (LSM) the Central electronic module (CEM) (4/56) uses information from the vehicle's twilight sensor (7/12) for automatic switching between low beams and daytime running lights. In case of missing or incorrect signal from the twilight sensor the low beams are used as usual.
Daytime running lights are never active together with running lights. On vehicles equipped with ABL-lights, there is a diode by the "auto-position". This diode pertains to the ABL-lights' function and not the daytime running lights.
For certain markets, when Light switch module (LSM) is et in "position P", the daytime running lights are deactivated automatically and the parking lights are turned when the automatic transmission's gear selector changes to P- or N-position, or when the parking brake is activated.
The light switch module (LSM) is directly connected to the central electronic module (CEM). Power is supplied to the daytime running lights, via a directly connected relay (2/152), from the central electronic module (CEM).

Turn signal lamps / Hazard warning signal flashers




This function is controlled by the left control stalk (3/133). The steering wheel module (SWM) (3/254) sends signals via the control area network (CAN) to the central electronic module (CEM) (4/56) to activate the turn signal lamps (10/13-14 and 10/47-54).
To activate the indicator for the turn signal lamp and to supply the turn signal lamp with voltage directly via one output, the central electronic module (CEM) transmits information to:
- driver information module (DIM) (5/1)
- driver door module (DDM) (3/126)
- passenger door module (PDM) (3/127)
- trailer module (TRM).
The turn signal lamps in the door mirrors are supplied with voltage via the driver door module (DDM) or the passenger door module (PDM).
If a trailer or similar is connected the symbol for a trailer in the driver information module (DIM) will be activated in time with the indicator light for the turn signal lamp.
The power supply is pulsed and the turn signal lamps are activated 90 times per minute.
The hazard warning signal flasher is activated by closing the switch (3/6) and transmits a signal to the central electronic module (CEM) to start the function. The central electronic module (CEM) transmits a signal in the same way as when activating the turn signal lamp, but to both sides. The central electronic module (CEM) also transmits a signal to the bulb in the switch to indicate that the hazard warning signal flashers are on.
If the ignition key is in position I or II, there is a clicking sound from the driver information module (DIM). If the ignition is switched off, there is no sound, but the hazard warning signal flashers continue to flash.
If a fault occurs with a lamp, the central electronic module (CEM) detects the reduction in power consumption and the frequency is doubled on the side where the fault occurred. The display in the driver information module (DIM) will occur at twice the frequency.

High level stop lamp




When the stop lamp switch (3/9) is closed, a signal is transmitted to the central electronic module (CEM) (4/56). The high mounted stop brake lamp (10/19) is supplied with power directly from the central electronic module (CEM). The stop lamp is supplied with power for as long as the stop lamp switch is closed.

Courtesy lighting/sun visor/glove compartment lighting




The interior roof lighting front (10/22) and rear (10/150) a total of four lamps is activated by the relevant switch.
The inner roof lighting and courtesy lighting (10/97-102) is automatically activated when a door is opened, when unlocking using the remote control or when activating the approach lighting.
In order for the automatic activation to function the light switch in the roof console must be in the auto position. This only applies to roof lighting. The courtesy lighting is activated regardless of the position of the light switch.
The interior roof lighting and the courtesy lighting is powered by the central electronic module (CEM) via the relay for courtesy lighting (2/89). The interior roof lighting and the courtesy lighting can be dimmed when the central electronic module (CEM) activates/ deactivates general lighting. This is because the return cable from the interior roof lighting to the Central Electronic Module (CEM) can be controlled.
Courtesy lighting activated:
- when the request for courtesy and roof lighting is transmitted from the remote receiver to the central electronic module (CEM) using serial communication
- when the remote control receiver has received a command to unlock from one of the remote controls
- when one of the doors is opened.
The lighting in the sun visors (10/114-115) and the lighting in the glove compartment (10/29) is powered by the central electronic module (CEM) via the relay for courtesy lighting (2/89). The lighting in the sun visor is activated when the cover for the vanity mirror is opened. The lighting in the glove compartment is activated when the cover for the glove compartment is opened.

Cargo compartment lighting




The cargo compartment lighting is activated when the trunk lid is opened. When the trunk lid opens the switch in the trunk lid lock unit (3/78) is activated.
The lighting (4 door 10/24, 5 door 10/25) is powered by the central electronic module (CEM) (4/56) via the relay for courtesy lighting (2/89).

Horn




The horn (16/10-11) is operated when the steering wheel module (SWM) (3/254) receives a signal from the switches in the steering wheel. The steering wheel module (SWM) transmits information via a directly connected cable to the central electronic module (CEM)(4/56) indicating that the switch is closed. The central electronic module (CEM) activates the relay (2/17) for power supply to the horn.
