MODULE INTRODUCTION
FAM/IPM/RAM consists of a power board and an electronic board. The power board contains circuit protection devices
and switching devices. The electronic board uses Intelligent Power Switching (IPS) for HS/LS load control, logic
functions and CAN/K- Line communication. The power board and electronic board are connected with pin blocks for
the Front Area Module (FAM) and VCD (Variable Connection Displacement) for the In- Panel Module (IPM) and the
Rear Area Module (RAM).
b.When the multifunction switch is not in postion headlamps turned on or autolight
c. 20 mn after the driver door is open
d. 20mn after IGN leaves the positions RUN to ACC or OFF
e. If IPM receives RKE "LOCK" command two times
3. Escort function enables only "Head Lamp Low Beam", so Park/Tail lamp should be turned off when driver door is
opened at key out (Battery Saver function).

Interior Lighting Functions
Room Lamps
1.The room lamps are can be controlled manually using the 3 - state (ON, DOOR, OFF) switch or by the Rear Area
Module (RAM). A main switch, located to the left of the steering wheel, is used as a master control switch. The
operating logic of the lamps will vary based on the position of the main switch ON, DOOR, or OFF).
2. Working conditions
a. The functioning depends on the key position in the key cylinder (OFF, ACC, RUN or START)
b. When the key goes in RUN or START position while the room lamps are decaying, then the room lamps are
turned off immediately.
c. When the Ignition key position is RUN or START and the last door is closed then the room lamps are OFF.
d. If the room lamps have been activated using the RKE UNLOCK function, and the ignition switch is turned to the
RUN or START position, the room lamps will be immediately turned OFF..
e. If the Ignition sw status is in RUN or START and Unlock information occurs, then the room lamp status is not
changed.
f. When the system enters to ARM WAIT mode by Remote Key or Mechanical cylinder lock switches the Room
lamp should be turned off immediately.
g. If there is RKE Lock signal at any door open, all doors should be locked first and wait for the all door close. No
action is taken while the Open Door status is OPEN and the doors are locked. Then when Open Door status
changes from OPEN to CLOSE, Room lamps will be OFF immediately.
h. The 30sec timer does not depend on the key reminder status.
i. If the main switch is changed to ON from DOOR after 20minute lamp OFF, all the lamps are turned ON.
j. If the Open Door status changes from OPEN to CLOSE (all doors close) when ignition switch is on RUN
position, room lamps and door courtesy lamps should turn off immediately (Do not decay off).
k. After 20minute Room Lamp OFF at door open, Room lamps are turned ON again when:
a. One of the door open switch's status changes. (Open to Close or Close to Open)
b. Ignition key is in RUN or START Position.
c. Receiving an UNLOCK event while a door is open and Main Room Lamp Switch is in the DOOR position.
l. For the room lamps, when the 20m timer is running and any of the side doors is opened the timer is restarted.

Luggage Lamp
1. Working Conditions
a. The 20min timer does not depend on the key reminder status.
b. After 20minute Luggage Lamp OFF at tailgate open, luggage lamps are turned ON again when:
a. Tailgate close and then tailgate is opened again
b. Ignition key is in RUN or START position.

Key Hole Illumination
1.
Working Conditions
The key cylinder is illuminated when the driver and / or the assist door are open.
2. Key hole extinguish conditions:
a. The key cylinder is turned off 10s after the driver and assist doors are closed.
b. The key cylinder is turned off immediately if the key is inserted in the hole and put to RUN or START position.
c. For vehicles equipped with BurglarAlarm, the key cylinder is turned off immediately when the system goes to
ARM WAIT mode during the 10s after the driver and assist doors are closed.

Panel Lights, Switch Illumination
1.Working Conditions
The MF "high beam" and "flash to pass" switches do not influence the management of the Panel Lights and Trip
Computer illumination, Rear Blower illumination and Rear Monitor illumination.
2. Functional Diagram
Adjustable Pedal(non-ims)
1.Adjust Pedal allows to activate Adjustable Pedal feature for the non- IMS equipped vehicle, IPM needs to control
the power source (by relay coil control) of the adjustable Pedal switch unit.
There is no Adjustable Pedal switch for Non- IMS version.
2. Functional Diagram
Reverse Drive Exterior Side Mirror
This function is implemented by the DDM. This function turns the 2 external reverse mirrors down when gear box in
reverse position.
Quarter Glass Open/close
1.Working Conditions
This Function is available when Ignition key is in RUN position and for 30sec after end of RUN.
a. Quarter glasses can be controlled by switches situated near driver or switches situated near rear passengers
seat (3rd row of seats).
b. When the switch is pressed the motor output is ON until the switch is released or after 5+/- 1sec. The switch
has to be released and pressed again to command the motor output ON again.
c. If power window lock is activated only driver window is enable by driver side switch and no switches are enable
to open quarter glass.
d. There is no interaction with the sliding doors. It is not forbidden to open the quarter glasses when the sliding
door on the same side is open.
e. No switch information (driver or rear passenger ) prevails on the other. If the main switch and the passenger
side switch are pressed in opposite direction at the same time, window stops moving.

Open Fuel Filler Door
1.Functional Diagram
1.The aim of this function is to receive the key fob signal and decode it. There are 8 different data included in the
radio frequency frame sent by the RKE to the IPM module:
a. Central door lock
b. Central door unlock
c. Panic function
d. Driver door window close (long press on RKE lock button)
e. Driver door window open (long press on RKE unlock button)

(separate device).
3. Input/Output Definition and Characteristics
Central Lock/unlock
1.Central locking/unlocking logic is controlled by IPM. Locking/Unlocking inputs are located in ADM, DDM
(Lock/Unlock switch, door knobs, door key cylinder) and in IPM (RKE receiver).
2. Locking/Unlocking actuators are located in ADM for passenger door, DDM for driver door and RAM for sliding doors
and tailgate.
There are 5 ways of operating central lock/unlock:
a. With Key RKE
b. With Door Lock/Unlock switches located on ADM/DDM
c. With Door Lock Monitoring switches located on the passenger/driver door
d. With Door/Tailgate Key Cylinder Lock/Unlock switches located on the tailgate or passenger/driver door.
3. Functional Diagram
Key Reminder Unlock
1.Key reminder door unlock does not take into account the lock/unlock commands from RKE, key cylinder or door
lock switches. It only takes into account the state of the door lock monitoring switch, key reminder switch and door
open status in order to proceed with the unlock sequence or not.
2. Functional Diagram
Remote Keyless Entry Panic
1.Working Conditions
RKE panic function is only active when the key is out of key cylinder.
Once started, panic operation is not stopped when ignition key is inserted, ignition is ACC, RUN or START, or
door is opened or closed.
