E 350 4MATIC Sedan (212.087) V6-3.5L (272.977) (2010)
Function sequence for last stopping reason
The rear window roller sun bind motor can be switched off for various reasons. The last stopping cause is stored by the rear SAM control unit.
Causes may be:
-
New request during active actuation
-
Recognition of blockage
-
Expiration of maximum time for extending/retracting
-
Command "Stop" via diagnosis
-
Recognition of hardware fault
-
Overvoltage
-
Reaching target position
Function sequence for last actuation duration
The actuation duration is stored each time the roller sun blind is actuated in the rear SAM control unit.
Function sequence for maximum actuation duration
If the rear roller sun blind is not switched off due to a fault, an operation request or timer control, the maximum value of the actuation voltage for
extending and retracting is stored separately. This allows determination of how the electrical and mechanical characteristics of the rear window roller sun
blind motor can be controlled for various vehicle and under various operating conditions.
Function sequence for maximum power
The maximum measured current is stored. This also allows experience to be gained on the variation of electrical and mechanical characteristics.
Function sequence for motion counter
The counter is increased by one for each actuation. This allows determination of how often the rear window roller sun blind motor has run in a vehicle.
