2002 Infiniti I35FACTORY OEM SERVICE PROCEDURE

Synchronization Of Power Windows

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.
