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).
Gearbox Status
The status of the gearbox is sent on the CAN network when the CAN network is available.
Oil Pressure Switch Status
The status of the oil pressure switch is sent on the CAN network when the CAN network is available.
Fuel Filter Status
The FAM receives on digital input the status of the fuel filter (Fuel Filter Input) and sends it (Fuel filter switch) on the
CAN network.
Washer Fluid Sensor Status
The FAM receives on digital input the status of the washer fluid sensor and sends it on the CAN network.
If Washer Fluid Low Input is LOW for more than 10 sec, FAM sends the warning message.
Seat Belt Warning Status
The IPM receives on digital input the status of the seat belt switch and sends the seat belt warning on the CAN
network.
If the Ignition switch status is in RUN or START when the Seat Belt Sw Input is FASTENED, the seat belt warning
indicator is blinking for 6 seconds.
When Seat Belt switch Input is NOT FASTENED, the seat belt warning indicator is blinking for 6 seconds.
If the Seat Belt switch Input is FASTENED during the 6 seconds, the seat belt warning indicator is blinking till the end
of the 6 seconds.
In North America:
the seat belt warning indicator is blinking when Ignition switch is on the status RUN or START and Seat Belt Sw Input
is NOT FASTENED.
Parking Brake Indicator
The indicator manages 3 functions: brake fluid sensor, parking brake warning and vacuum switch.
The vacuum function is available for diesel engine only
The FAM receives on digital input the status of the vacuum switch and the ABS EBD warning and sends them on the
CAN network.
The status of the vacuum switch and the ABS EBD warning are sent on the CAN network when the CAN network is
available.
The FAM receives on digital input the status of the brake fluid sensor and sends it on the CAN network.
The status of the brake fluid sensor is sent on the CAN network when the CAN network is available.
The IPM receives on digital input the status of the parking brake switch and by CAN network the status of the vacuum
switch, the status of the ABS EBD warning, the status of the brake fluid sensor and the speed of the vehicle.
switch, the status of the ABS EBD warning, the status of the brake fluid sensor and the speed of the vehicle.
The IPM sends the park brake indicator control on the CAN network.
The indicator is lighted if the vacuum switch or ABS EBD warning are on or brake fluid sensor is low or park brake
switch is on.
If the speed of the vehicle is over 10 km/h and ignition switch is on the status RUN the park brake indicator control is
blinking at 50% duty in 0.6 second if Parking Brake switch Input is active. In this case Vacuum switch, ABS EBD
warning and Brake Fluid sensor are ignored.
The park brake indicator is blinking on the same time that the chime is ringing. If a CAN signal among Vacuum switch,
EBD warning or Brake Fluid Sens switch is INVALID, out of range or not received this CAN signal is considered to be
OFF.
If VehicleSpeed CAN signal is INVALID or not received, it is considered to be 0 kph.
Charging Voltage Control
The IPM receives on analog input the voltage of generator and sends a warning.
When the voltage of generator L pass strictly above 10V, the state of the CAN variable.
Turn Indicators Status
The status of the turn indicators are sent on the CAN network when the CAN network is available.
High Beam Status
The status of the high beam is sent on the CAN network when the CAN network is available.
Front Fog Lamp Status
The status of the front fog lamp (lightning and state of the bulbs) is sent on the CAN network when the CAN network
is available.
Doors Open Warning
The RAM receives on digital input the status of the driver door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the passenger door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the left sliding door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the right sliding door open switch and sends it on the CAN network.
When vehicle speed is under 10 kph, with ignition key not inserted and any door OPEN, DoorsOpenWngCtrl stays ON
for 20 min and then is turned OFF.
Tailgate Open Switch Status
When vehicle speed is under 10 kph, ignition key is inserted and Tailgate open switch is OPEN, Tailgate Open
warning stays ON forever (IPM can enter sleep mode).
When vehicle speed is under 10 kph, with ignition key not inserted and lgate open switch is OPEN, Tailgate Open
warning stays ON for 20 min and then is turned OFF.
Chime Control
1.The chime warns the driver that a problem is occurred.
These warning are:
a. Seat belt
b. Parking on
c. Over speed
d. Key reminder
e. Light Warning
f. Doors Open
g. Tailgate open warning
2. Chime sound priority:
a. 1st : Seatbelt warning
b. 2nd : Overspeed warning
c. 3rd : Door open warning
d. 4th : T/Gate open warning
e. 5th : Key operated warning
f. 6th : Parking Brake warning
g.7th : Light ON warning
h. 8th : Key learning sound
3. If two different warning condition happen at the same time, chime should work only for the highest warning
condition.
4. Cluster indicators should work for two warning behavior.
5. Behavior Description

Over Speed Warning
The IPM receives the overspeed warning by the CAN network.
The chime is actived when the overspeed speed warning is on the state Overspeed.
Key Reminder Warning
The IPM receives the status of the key on digital input.
The IPM receives the status of the driver door open switch by the CAN network.
The chime is activated when key is inserted and the driver door is open.
Light Warning

sends it on the CAn network.
The IPM receives by CAN network the speed of the vehicle.
The doors open warning chime is activated when one or several of the 4 doors is opened and the speed of vehicle is
over 10km/h.
Tailgate Open Warning
The RAM receives on digital input the status of the tailgate open switch and sends it on the CAN network.
