MoDiC Operation
2001 BMW 330Ci Convertible (E46) L6-3.0L (M54)SECTION MoDiC Operation
MoDiC Operation
The MoDiC is switched on by pressing the ON/OFF button on the control panel. Before the start mask appears, the following procedures are carried out:
- System boot
- Temperature check
- Buffer battery check
- Main battery check
- Power on internal self test
- Start screen is displayed
Suspend Mode
The MoDiC will switch to the suspend mode after a period of time when no activity has taken place.
The suspend mode is a power saving mode that is designed to save battery power. The MoDiC switches to the suspend mode in three steps as follows:
Stage 1 (doze mode): The computer's clock pulse frequency is reduced to save power
Stage 2 (sleep mode): The hard disc is switched to the economy mode to save power.
Stage 3 (suspend mode): All internal components are switched off, but the content of the working memory is saved.
Any of the power-economy stages will be terminated if the touch screen is pressed. The suspend mode can be manually activated or deactivated by pressing the suspend mode button in the control panel.
Detailed Operation Instructions:
Refer to the Handbook included with the MoDiC for in-depth setup, initial boot-up and cleaning/maintenance procedures.
Refer to IDC bulletins for version specific software loading instructions.
