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).

Easy Access
1.Description
The easy access function permits automatic rearward movement of the driver seat when the key is removed from
the cylinder. Automatic forward movement of the driver seat will take place when the key is inserted into the
cylinder. This function will be enabled on IMS equipped vehicles when the AUTO button is pressed.
Inhibit Switch should be in P- Position for the Easy Access operation.

2. Functional Diagram

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.

Battery Removal
a.If the battery is removed with the system in the ARM state, the system will be placed into the ARM state upon
battery reconnect.
b. The ALARM state will be re- activated if the battery is disconnected, then reconnected, with the system in an
ALARM state.
c. If the battery is disconnected and reconnected with the system in AFTER ALARM state, the alarm will be re-
activated.
d. The system will enter DISARM mode if the battery is disconnected during the ALARM WAIT state.
Panic
a.If RKE PANIC signal is received, Siren output and hazard lamp operate for 27 seconds and the system return to
the previous state as soon as the PANIC function finishes.
b. The PANIC function will be stopped if any RKE signal is received during PANIC activation..
c. If Key reminder switch is ON during PANIC function is operating, PANIC is stopped immediately.
d. If the system goes to ALARM mode during PANIC function is operating, PANIC is stopped immediately and then
ALARM function should be activated.
e. During ALARM state;
If RKE PANIC signal is received, ALARM mode is maintained and PANIC function should be ignored. ALARM has
higher priority than PANIC function.
f. During AFTER_ALARM state;
If RKE PANIC signal is received, AFTR_ALARM mode is maintained and PANIC function should be activated.
Safe & Rescue Mode
The goal of those modes is to be able to cope with failures that may happen on some of the most critical
functionalities (for the driver security) of the system.
Safe Mode
The safe mode is entered in case of system problems such as:
a. Incoherent inputs on monitored signals. In this case, safe mode is the debouncing time before the inputs are
considered INVALID. Note that today, we have no way to detect if the rain/light sensor is in working operation or
not. It means that a driver action will be required in case of failure of this sensor;
b. Loss of the CAN frame containing the monitored signal:
c. Loss of the CAN network: CAN goes to BUS OFF state, safe mode is the time necessary for detecting the BUS
OFF state.
In all cases, the action in safe mode is to maintain the previous state of the system (for lighting and wiping). The list of
monitored signals is the same as in rescue mode
Exiting Safe Mode
The software safe mode is exited and the module goes back to the normal mode when: a. On IPM, hardware inputs return to a coherent state;
b. The lost CAN signal comes back while timeout has not elapsed;
c. The CAN network returns to a normal state without reaching BUS OFF state.
Software safe mode is also exited when the software rescue mode is entered (problem does not disappear).
Hardware safe mode is exited and the module goes back to normal mode if the internal problem disappears (watchdog
is properly triggered again). If the problem stays, hardware safe mode is exited to enter hardware rescue mode.
Rescue Modes
The rescue mode consists in activating some safety functions when IGN2 = ON: a. Switch on the low beams (FAM), park lamps (FAM), tail lamps (RAM) and cluster backlighting (IPM);
b. Unlock of all the doors when the rescue mode is entered with IGN2 = ON
c. Front wipers do not need to be turned on by software in rescue mode because wipers can be turned on by
manually setting the MF switch to low speed. The FAM software must keep the same state as before entering the
rescue mode.
d. When IGN2 = OFF, low beams, park/tail lamps and cluster backlighting are turned off.
Entering Rescue Modes

Rescue mode is entered when some important CAN signal or hardware input are not available. Rescue mode is
entered when one of the following conditions is true:
IPMa. Timeout on CAN signal InhibitSwSts, to detect loss of CAN connection with FAM.
b. Timeout on CAN signal StopLpErrorSts, to detect loss of CAN connection with RAM.
c. MF Light Switch information is invalid: when the signals coming from MF Light Switch are not coherent for more
than 2 s, CAN signal ParkTailHeadLpCtrl is sent with INVALID value and rescue mode is entered.
d. Front Wiper MF Switch information is invalid: when the signals coming from Front Wiper MF Switch are not
coherent for more than 2 s, CAN signal FWiperCtrl is sent with INVALID value and rescue mode is entered.
e. CAN is in Bus Off state
RAM a. Timeout on CAN signal InhibitSwSts, to detect loss of CAN connection with FAM.
b. Timeout on CAN signal ParkTailHeadLpCtrl or FWiperCtrl, to detect loss of CAN connection with IPM.
c. ParkTailHeadLpCtrl = INVALID or unknown value
d. FWiperCtrl = INVALID or unknown value
e. CAN is in Bus Off state
FAM a. Timeout on CAN signal StopLpErrorSts, to detect loss of CAN connection with RAM
b. Timeout on CAN signal ParkTailHeadLpCtrl or FWiperCtrl, to detect loss of CAN connection with IPM
c. ParkTailHeadLpCtrl = INVALID or unknown value
d. FWiperCtrl = INVALID or unknown value
e. CAN is in Bus Off state
For all CAN signals, timeout duration is 2.5 times signal periodicity.

2.The IPM communicates with the diagnostic tester directly. But other units operate self diagnostic, input/output
monitoring and actuator operation via the IPM using the CAN communication.
