| The window regulators are enabled when: |
| The onboard supply control unit -J519- sends the signal "terminal 15 on" via the convenience CAN. |
| The convenience system central control unit -J393- transmits the signal to enable the window regulators to the front door control units via the convenience CAN. The rear door control units receive this command via LIN bus from the front door control units. |
| After the transition from "terminal 15 on" to "terminal 15 off" the enable signal is maintained for 10 minutes. This run-on time is interrupted if one of the two front doors is opened or the vehicle is locked with the remote control. |
| There are 3 different states: |
| t
| Ignition off, window regulators not enabled |
