Storage Mode
By switching "OFF" the battery switch, the Power Module goes into Storage Mode 30 minutes after terminal R switches off.
The following CC message appears:
Before disconnecting, the PM sends out the "Shutdown" signal. After a further 90 seconds the shut down is completed. If the ignition switch is turned to terminal R "On", a Check Control message is issued which informs the driver that the vehicle is in Storage Mode.
The following CC message appears:
When the signal "15w" or change-over of the battery switch to "closed-circuit current monitoring" is detected, the electronic battery master switch is closed.
The car can still be started and driven in storage mode. All systems remain functional. The CC message remains active.
When "Terminal R Off" is active, disconnection is carried out after 30 minutes (as explained above).
