PMM (Passenger Memory Mirror)
The PMM is located inside DSP2 (Door Switch Panel 2). The PMM is existing only when the
vehicle contain OSRVM memory, and exist with or without OSRVM fold.

Functional description PMM
The PMM is together with the DMM (Driver Mirror Module) is
connected to LIN bus 8 where the MSM (Memory Seat Module) is
the master.
There is no mirror switch in the PMM and hence only execute the
commands sent out on the LIN bus 8 from the MSM. The mirrors
is controlled either by the driver from the DMM which sends the
command for the desired operation (up/down, left/right or
fold/unfold) movement to the MSM which then sends out the command to move the mirrors
or by the stored position within the memory in MSM when the memory buttons on the driver
seat is activated.

Functional description PSM
The Power Sounder Module provides an integrated piezo speaker and an internal battery. It
will sound any alarm discovered by the BCM or by itself: this can be a disconnect of cables
or the loss of voltage in the internal battery.
The internal battery is charged by the car’s generator. It is used to supply the module even if
the car’s battery is disconnected.

RPD (Remote PRND Display)
The Remote PRND Display is a part of the automatic shift
control assembly. It indicates the selected gear:
• P(ark)
• R(ear)
• N(eutral)
• D(rive)
The selected gear is indicated by a LED. RPD communicates
with the BCM on the LIN bus LIN2.

Rain Light Module (RLM)
RLM is installed in order to collect information about rain and ambient light. Based on that
information, wipers and lights can be switched on.
There are two versions:
• RSM = Rain Sensor Module.
• RLM = Rain/Light Sensor Module.

(detection of both rain and ambient light)

Functional description RSM
Rain Sensing
Rain sensor automatically activates wipers
during rain or splash conditions maintaining
maximum visibility.
A light ray is sent out to the windshield. If
there are drops on the screen the ray is
186
Page 188
reflected. A receiver installed in the RSM measures the rate of reflection. The optical
sensitivity is less than 0,2mm².
Light Sensing
Light sensors are provided to enable automatic headlight
activation. To determine the required information both
the horizon sensor (for tunnel detection etc.) and the
day/night sensor (faced upwards) are used.
There are some features that guarantee the reliability of the module:
• Immune to false headlight On / Off requests caused by street lights, shadows, and
oncoming headlights.
• Headlamps remain off when traveling through underpasses or when stopped at an
overhead covered ATM or drive through.
• Tunnel entry is detected and headlamps are quickly activated under a wide range of
conditions.
• Allows Day /Night sensitivity adjustment of the rain sensor.
• Headlamps switch on when entering a tunnel, garage, or carport.
• Headlamps are not activated by overpasses.

SRC (Sunroof Controller)
The Sunroof Controller is a functional system for opening and closing both the sunroof and
the sunshade. Therefore two versions of the SRC are developed: SRC1 is responsible for the
sunshade movement, SRC2 controls the sunroof.
