GF82.85-P-2006QMJ Switch On/Off Behavior, Function
- with CODE (498) Japanese version
Activating navigation
The navigation system is activated automatically via the class B (interior) controller area network bus (CAN-B) when the driver door is opened. If the digital versatile disk (DVD) is inserted, this process may be accompanied by faintly audible noises from the DVD drive integrated in the navigation processor. The display of the COMAND operating, display and control unit (A40/3) remains switched off. If no status change occurs at the EIS [EZS] control unit (N73) (e.g. circuit 15C ON), the navigation system remains activated for 30 minutes.
Activation of entire system
All other subsystems are activated when the transmitter key (A8/1) is inserted into the EIS [EZS] control unit (N73) in position 0 (circuit 15C ON). The display is switched on in position 1 (circuit 1 5R ON) of the transmitter key (A8/1).
This is providing that the COMAND operating, display and control unit (A40/3) was switched on before the transmitter key (A8/1) was last removed. The system that was active before the key was last removed (e.g. radio) is switched on and the corresponding main menu is displayed. If the COMAND operating, display and control unit (A40/3) was switched off for more than 30 minutes, then a message appears with general information about how to use the system.
Conduct when pushing "ON" button
The COMAND operating, display and control unit (A40/3) can also be switched on when the transmitter key (A8/1) is removed by pressing the "ON" button. All functions are then available for 30 minutes. When 30 minutes has elapsed, the COMAND operating, display and control unit (A40/3) switches itself off automatically.
If switching off has occurred after 30 minutes, the system can be switched on again by pressing the "ON" button, thus the 30-minute run-on time starts again.
Switch off characteristics
The COMAND operating, display and control unit (A40/3) is switched off when the transmitter key (A8/1) is removed (circuit 15C OFF). The 30 minute run-on time (standby) of the navigation system begins. During this period all the important positioning parameters are stored. Moreover the COMAND operating, display and control unit (A40/3) is always in "standby" when CAN-B is active.
Switch off characteristics at undervoltage
The COMAND operating, display and control unit (A40/3) constantly monitors battery voltage. Depending on the voltage value the system will act as follows:
If the battery voltage drops below 11.5 volts (battery warning range), a message appears on the display which requests the engine to be started. If the engine is not started up, yet another warning is issued after 3 minutes have elapsed indicating that only 10 s remain to switch the engine on before the system is run down. In this case switching on the engine prevents the system from being automatically shut down. If the system has shut off and the voltage increases to more then 11.5 V again, the COMAND operating, display and control unit (A40/3) does not switch itself on again automatically.
If a system has been shut down it can still be switched back on again manually. The warning procedure then ensues for as long as the fault is not eliminated.
Battery voltage below 9.5 V (undervoltage)
The COMAND operating, display and control unit (A40/3) is automatically switched into a defined standby condition, in which only the battery voltage continues to be monitored.
In addition to this the current operating condition is stored. The COMAND operating, display and control unit (A40/3) cannot be operated or accessed using STAR DIAGNOSIS when it is in this condition. Communication with external components does not take place.
