X Series E70 X5 3.0Sd (M57T2) OFFRD
•
Visual alarm after anti-theft alarm has been triggered
(the visual alarm is given as per encoding with hazard warning lights, turn signals with dipped
headlights or turn signals with main-beam headlights.)
•
Actuation of bi-xenon headlamps
•
Control of the stepper motor controller for the adaptive headlights
•
Turning light
The turning lights are coupled to the adaptive headlights.
All lighting functions except the additional brake light are supplied with a pulse-modulated signal by the
footwell module (FRM). This PWM signal allows constant brightness of exterior lighting.
Interior lighting
On vehicles without roof control panel (FZD), the footwell module actuates the interior lighting in the roof
area directly.
All footwell module outputs for interior lighting are pulse-width modulated. This ensures that the brightness
of the interior lighting always remains constant in spite of voltage fluctuations.
With standard equipment, the interior lighting comprises the following components:
-
Front interior light
-
Luggage compartment lighting
-
Glove compartment lighting
-
Footwell lighting
The following components can also be installed as special equipment for the interior lights:
-
Rear interior light
-
Courtesy lighting
Central locking system
The footwell module evaluates the status of the Hall sensors in the door contacts.
When the vehicle is locked or unlocked with the mechanical key element, the footwell module will recognise
this request. The footwell module will send a message through the K-CAN to the CAS (Comfort Access
System).

Power windows
The footwell module (FRM) and the junction box electronics (JBE) actuate the power window drives.
The relays for the front power window motors are located in the footwell module. The relays for the rear
power window drives are located in the junction box electronics.

Preconditions for activation
The footwell module (FRM) receives a large number of input signals that switch on the interior lighting. The input
signals are directly read into the footwell module or are received via the K-CAN.
The following signals switch the interior lighting ON:
•
Interior lighting button pressed
