System Description: Outline

Power window system consists of

• BCM (Body Control Module)
• driver's door control unit (LCU1)
• passenger, rear LH, RH door control units
• four power window regulators

BCM is connected to driver's door control unit (LCU1) via DATA LINE A-3, and driver's control unit (LCU1) and other door control units supply power and ground to each power window regulator.

When ignition switch is in the "ON" position, power window will be operated depending on power window sub/main switch (which is combined with each door control unit) condition.
