Description And Operation
The power window system is managed by the Body Control Module (BCM) and by the LIN bus electronics integrated in the power window motors.
The vehicle operator can actuate the power windows using the power window switches on the door panels. All of the power windows on the vehicle (front and rear) can be operated using the master switch (l) on the driver side door panel. The front and rear windows can be operated from their respective switches.

The passenger side power window switch is defined as a module because of the LIN type electronics integrated in the switch.
REAR POWER WINDOW SWITCH
Each rear door will come equipped with a power window switch.
The front and rear power window regulator motors are secured to the carrier plate using four.
The front and rear power window regulator motors incorporate an electronic unit which communicates data with the BCM over the LIN bus data network. The integrated electronic unit provides a supply to the power window regulator motors in both of the "up" and "down" modes.

| (*) - Ground from the BCM | |

All power window switches are connected to the BCM. When a switch is operated, the BCM receives the signal and actuates the power window regulator motor over the LIN data bus to operate the desired power window operation.
In the following "key status" conditions:
- OFF
- ON
- ENGINE RUNNING
- CRANK
The power window regulator motors actuate only if the LIN line through which it communicates with the BCM is in normal operating conditions. The power window regulator motors cannot move the window if the LIN data line is in sleep mode or no longer in normal operating conditions.
The LIN data line enters sleep mode three minutes after "key status" is set to OFF position. During the three minutes after key-off, the LIN line is active and the window can be moved (Comfort Enable function). If the driver or passenger door is opened in the course of the three minutes, the Comfort Enable function is deactivated.
The windows can only be operated the battery voltage range of 10V (+/-0.6V) - 16V (+/-0.6V).
