841006934 - E3051 ELECTRIC REAR WINDOWS DESCRIPTION (Passive Entry )
Description
The rear electric window can be activated only with key-on (INT) except when the windows are closed/opened centrally via the Passive Entry control unit and during the timed period with key off.he device is excluded temporarily during start-up (INT/A). Operation of the rear windows with key off (STOP) must be possible only in manual mode unless one of the doors is opened (when all movements are deactivated) and in any case within the timed period calculated and managed by the Body Computer. This applies during the first few minutes following transition from Key-on (INT) to key-off (STOP).The rear window motors are controlled by keys on the relevant doors in manual and automatic mode in accordance with the following strategy:
if the length of time for which the control key is pressed is between 50 and 300 milliseconds, operation is manual. the glass goes up/down only with the key pressed;
f the key is pressed for longer than 300 milliseconds, operation is automatic: the window continues to go up/down until it reaches the end of its travel or the control key is pressed again;
if the key is pressed for less than 50 milliseconds, this is ignored (it is treated as an accidental knock).
Movement of the rear windows may also be determined by controls on the driver side door control unit, which are sent to the engine bay control unit via the CAN line.When the rear window function inhibition key on the driver side front door control unit is pressed, the rear windows cannot be controlled locally. The symbols on the rear control keys must also be off.Inputs on the boot compartment control unit receive information from the doors to indicate the presence of a possible obstacle in the path of the rising window (antipinch function). This occurs in both manual and automatic mode.If this happens, the relevant control unit must immediately interrupt the glass travel and then reverse the direction for 300 ms.f the antipinch protection is activated, the node that manages window movement receives a signal indicating that the seal has been compressed by means of a resistive sensor fitted into a coating applied to the upper right or left window seal. If the instrument panel receives one or more fault messages from the window antipinch seal coatings via the CAN network, it displays the relevant message on the matrix display. The window central locking function (also applicable to the sun-roof) See E3060 SUN ROOF
from the climate control unit that detects the presence of exhaust gas via a specific sensor (with key-on) See E6020 AIR CONDITIONING
keeping the boot handle or key pressed for at least 2 seconds (with key-off). The windows now begin to move and motion continues for as long as the handle is pressed. The function is activated only if the person is in possession of a CID.
can be activated by means of specific signals sent to the Body Computer:
