The system exits this state if the ignition signal is switched on (cf. Z2 in DOC02092), a backlight control
button is pressed for at least half a second while ignition signal is on or following a wakeup event. This
wakeup event can be the wakeup timer, a GSM incoming call, a SMBus event or a request from the MPC
processor board itself. If the board temperature e70°C during a wakeup event, the system goes into
state 9. Otherwise the MPC processor board is switched on and the system goes into sate 3. If the MPC
processor board does not start, the power supply is switched off and the system goes back into state 1 (error
1).
State 5: System powered up after a wakeup. The system cannot remain in this state for more than 30
minutes, to avoid vehicle battery draining. If this time elapses before the operating system shuts down on its
own, the IHMI-MPC board makes a request to the MPC processor board manager to shut down and the
system goes into state 6.
The MPC processor board manager could request to switch off the power supply (state 1), or to place the
board in standby (state 4). The user can request a change to state 6 by pressing simultaneously both
backlight control buttons during al least 2 seconds. It can also be requested by software (see
PROGRAMMING INTERFACES chapter for details).
If ignition signal is switched on, the system goes into state 3. If the board temperature reaches +85°C, the
IHMI-MPC board requests the MPC processor board manager to shut down the system and the system goes
into state 7.
State 6: Waiting for system shutdown. After ignition signal is switched off, if the operation time after a
wakeup is exceeded or at a user or a program request, the MPC processor board manager is requested to
shut down the system through a notification. The IHMI-MPC board waits for the module to turn itself off or to
place itself in standby. The user can force a module power off by pressing simultaneously both backlight
control buttons during al least 2 seconds. It can also be requested by software (see PROGRAMMING
INTERFACES chapter for details).
The system cannot remain in this state for more than 10 minutes (or 4 hours if system startup when ignition
signal turned on is disabled, cf. Z2 in DOC02092). After this delay, the MPC processor board is forced to
switch off and the system returns to state 1 (error 3). As soon as the board temperature r85°C , the
delay is reduced to 2 minutes. If ignition signal is switched on (or switched on again), the system goes (or
returns) into state 3.
Note: upon return to state 3, the fact that a request to shut down the system has been transmitted to the MPC
processor board manager must be taken into account.
State 7: Waiting for shutdown - system too hot. When the board temperature reaches +85°C, the MPC
processor board manager is requested to shut down the system. The IHMI-MPC board waits for module to
turn itself off or to place itself in standby.
The system cannot remain in this state for more than 2 minutes. After this delay, the MPC processor board is
forced to switch off (error 4). At the end of the wait period, the system goes into state 8 (shutdown) or state 9
(standby) if ignition signal is on, otherwise it returns to state 1 (power down) or 4 (standby).
State 8: Waiting for the system to cool down - Power down. The IHMI-MPC board waits until the board
temperature drops down to +75 °C before restarting the MPC processor board. If ignition signal is switched
off, the system goes directly into state 1.
State 9: Waiting for the system to cool down - Standby. The IHMI-MPC board waits until the board
temperature drops down to +75 °C before restarting the MPC processor board. If ignition signal is switched
off, the system goes directly into state 4.
State display
Every 10 seconds, a LED indicates the current system state by flashes of one tenth of a second every one
second. The number of flashes, in a 10 seconds period, is equal to the state number (defined in the previous
paragraph). If there is an error, the error number is displayed instead of the state until the system is restarted.
In this case, the flashes are replaced by half a second hiding.
