Synchronization Of Power Windows
WARNING: This page does not describe the selected car, but rather 164 other vehicles, including the 2002 Volvo V70, 2002 Volvo V40, 2002 Volvo S80, 2002 Volvo S60, and 2002 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
C-class models do not require synchronization of rear power windows. Synchronization procedure can also be performed with STAR DIAGNOSIS tester.
Synchronization of power windows links counter reading of window position to relevant Door Control Module (DCM). Synchronization must be performed whenever desynchronization occurs (battery disconnected or control module replaced). Synchronization is necessary for automatic raising/lowering function of power windows.
To synchronize power windows, press appropriate window switch in up position. When window reaches full up position maintain pressure for 3-5 seconds. When DCM detects motor lock-up for specified period position counter is reset to zero. Repeat procedure for each window.
