Power Sliding Door & Power Tailgate
1.Description
There are two sliding doors and one tailgate in the vehicle. A switch is fitted at each B- pillar to permit Power
Sliding Door activation.. For the tailgate, there is also one push button switch. These switches are used to send an
signal of 200 ms minimum to the PSD module (or PTG module).
2. Functional Diagram
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.

CLOSE signal.
b. RAM will pass this signal to LH PSD and RH PSD then the burglar alarm state is decided depending on the
vehicle condition.
f. PTG open/close
a. Only with the information received by RKE, the burglar alarm system cannot distinguish the OPEN signal from
CLOSE signal.
b. RAM will pass this signal to PTG module then the burglar alarm state is decided depending on the vehicle
condition.
g. Panic by key fob
a. Whenever this signal is received, the PANIC function is activated (unless the system is already in an ALARM
state).
2. Functional Diagram
Arm Mode
a.If 30 second timer is elapsed without any changes from the ARM WAIT mode, then system goes to ARM mode.
b. Whenever RKE lock signal is received in the ARM state, then the system makes a hazard flash (1 second) and
sends a door lock pulse.
Prearm Mode
a.If the vehicle is locked using the RKE transmitter, and one or more doors are in an OPEN state, the system issues
a LOCK pulse and enters a PREARM state." In the PREARM state, the hazard lamps do not flash".
b. If all doors are closed in the PREARM state, the system enters ARM WAIT mode, and the hazard lamps will flash
once.
c. During PREMARM state, if f key reminder switch is ON & IGN 1 & IGN 2 are turned on in this state, the system
immediately goes to DISARM state
Arm Wait Mode
a.The ARM WAIT mode is active for 30 seconds. If any entrance (hood, doors, tailgate) is opened, any lock knob is
moved to an UNLOCK state, or the ignition switch is turned ON, the system will immediately enter DISARM mode.
The system will enter ARM state if none of the previously mention conditions occur during the 30- second ARM
WAIT mode.
T1 : 0.5 sec
T2 : 1.0 ± 0.1 sec
Disarm Mode
a.If RKE unlock signal is received, then UNLOCK output is issued together with the flashing of hazard lamp (two
times) and the system enters into the DISARM condition.
b. When entering into DISARM from ALARM state, current alarm will be cancelled and burglar alarm relay drive
output is turned off.
c. When RKE unlock signal is received again in the DISARM state, UNLOCK output is issued again and hazard lamp
is flashed also (two times).
Alarm Mode
a.If one or more of entrances are opened in the ARM or REARM state, then Burglar alarm relay drive output is
turned ON in order to inhibit the start condition, and hazard lamp and siren are activated for once of 27 seconds
duration.
b. Siren output and hazard lamp should be synchronized to get the same output period.
c. Even though all the doors are closed during alarm, alarm continues to operate it for the remaining time.
d. When there is a new attack (with one of the entrance is still open) in the vehicle after completing the alarm output,
alarm should not be started again.
T1 : 27 sec ( - 0, +3sec)
T2 : 0.5 ± 0.1 sec
After Alarm State
a.If ALARM cycle is elapsed, the system goes into AFTER ALARM state.
b. During this state,
a. Burglar alarm relay drive output maintains ON.
b. Siren and hazard lamp output are stopped.
c. If another entry is opened during the AFTER ALARM state, the burglar alarm relay drive output remains ON, but
the siren will not be re- activated.
Rearm State
a.If all entrances are is closed during AFTER ALARM state, the system goes into REARM state.
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.
