System Block Diagram
Description
The driver door module(DDM) is a part of a Controller Area Network (CAN), and performs CAN communication with the FAM, IPM, RAM, ADM, IMS and SCM. Driver controls driver side power window switch button located inside of the driver side door to operate power window, mirror, door lock and unlock.
1. Two manual operations (up and down) for four p/windows. However, on the driver's seat the auto up/down operation must be possible.
2. Manually operating the mirror position by the manual switch (Up, Down, Right, and Left)
3. Saving and replacing the mirror position by RKE -> For 2 persons
4. Out side mirror auto reverse operation
5. Out side mirror fold/unfold power control
6. Central door lock/unlock function
7. Door courtesy lamp control
8. Out side mirror defog control
9. Illumination control
10. Outside mirror turn signal lamp control.

Reminder Operation By Memory Switch
1. When the each position switch is pressed at the ON state of the IGN2 or B+ (drive door open or for 30 seconds after drive door close), the mirror shall be positioned according to the memorized value.
2. If the position switch (POS1 or POS2) has not been memorized, then the reminding operation shall not be performed.
3. During reminding operation, if a position switch (POS1 or POS2) is pressed and then the latest pressed switch shall govern the reminding operation.
4. Prohibit Condition for the Reminding Operation
A. When the mirror manual switch is being operated.
