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.
Two manual operations (up and down) for four p/windows. However, on the driver's seat the auto up/down operation must be possible.

If Central door lock/unlock Sw is "on", driver door lock Sw Sts message is sent to lock/unlock.
If Key cylinder lock switch is "on", driver door key cylinder Sw Sts message is sent to lock.
If Key cylinder unlock switch is "on", driver door key cylinder Sw Sts message is sent to unlock.
If door lock Ctrl message from IPM is "driver door lock, driver door and assist door lock, rear door, tailgate and driver door lock, lock all", door lock actuator is locked for O.5sec.
If door lock Ctrl message from IPM is "driver door unlock, driver door and assist door unlock, rear door, tailgate and driver door unlock, unlock all", or lock actuator is unlocked for O.5sec.
Under the condition "IGN ON", if Crash Sensor Sts message from IPM is ON, Door UNLOCK makes output.(5 ± 0.5sec)
Remained action goes on irrespective of OFF signal of Crash Sensor Sts message.
Door Lock can't make output until IGN is OFF during or after Crash Action.
After Crash UNLOCK, Driver Door Key Cylinder Sw Sts and Driver Door Lock Sw Sts data are not sent to LOCK though key cylinder lock Sw and main door lock Sw is on until IGN is "OFF".
Unlock action is done again after 100ms if any door is still locked after Crash UNLOCK.
If Crash Sensor Sts message is sent on door, unlock action will be generated until IGN is “OFF”
If the vehicle is under any condition of the followings, all doors is locked.
If message from IPM is (Door Lock Ctrl = LOCK_ALL), it will be locked for 0.5sec.

If door is locked by using door lock knob after opening door while IGN Key is inserted to Key Cylinder, Unlock output will be for 1sec (IPM sends Key Remember Unlock Ctrl message to Long Unlock) and there will be a series of three outputs every 0.5sec if door condition is "Lock".
(IPM sends Key Remember Unlock message to Short Unlock)
If condition is unlocked during a series of three outputs, output will be stopped.
LOCK/UNLOCK by Key fob is run by Door Lock Ctrl message from IPM.
Operation in DDM is identical with Central Door Lock/Unlock.
If the priority is the low, it'll be ignored.

If there is a signal which has priority over existing action, it will be stopped Immediately and the signal makes its own action.
When was new output condition after existing output completion, send output after wait 100 ms by standard existing output completion point of time.(except CRASH UNLOCK, Without waiting TIME 100 ms immediately action enforcement)
Manual Control for O/S Mirror LH
At the ACC or RUN ON state, if the mirror select switch in the SW ASSY P/WDW MAIN is the LH state and the mirror direction switches (UP, DOWN, LEFT, and RIGHT) are operated, then the mirror motor shall be driven to control the mirror to the desired direction.
Manual Control for O/S Mirror RH
At the ACC or RUN ON state, if the mirror select switch in the SW ASSY P/WDW MAIN is the RH state and the mirror direction switches (UP, DOWN, LEFT, and RIGHT) are operated, then the driving signal shall be sent to the SW ASSY P/WDW MAIN through the CAN.
If the position switch (POS1 or POS2) within 5 seconds after the memory switch (‘SET’ SW) is pushed at the ON state of the IGN2 (the switch module shall send the state signal through can), the present mirror position shall be memorized. (The 5-second duration from the ON state of the memory switch is the memory allowance period so that the allowance state shall be released if the 5 second duration is passed. That is, if the position switch (POS1 or POS2) is ON during the memory allowance period, and then the present position shall be memorized.) Except, when the mirror manual switch at the LH is operated, the mirror position at RH shall not be memorized.
Inhibiting and releasing of saving mode may be carried out when any of following conditions is satisfied:
- If 5 seconds is elapsed after the memory switch is turned on
- If the ignition 2 is turned off
- When saving is completed
- If "Ignition Sw Sts" of the CAN communication data sent by the IPM is not "Run"
- If "Inhibit Sw Sts" of the CAN communication data sent by the CLU is not "P"
- If "Vehicle Speed" of the CAN communication data sent by the CLU is over "3Km/h
If the battery is removed, the memory must be cleared. (only position data)
In IGN On (IGN State = On) or Driver door opened or during 30 seconds after Driver door open to close when IGN Off Condition (It used IMS Main signal), if user press the position button, Outside Mirror is play to memorized position
The position switch (position1 and position2) that has not been saved yet cannot perform replacing.
If the user presses a position switch (position1 or position2) during replacing operation, the recently pressed switch will be prior to the other.
Replacing Prohibition Conditions
If the mirror switch on the LH side is pressed
If "position switch states" of the CAN communication data sent by the IMS is not "ON"
If "Vehicle Speed" of the CAN communication data sent by the cluster is "3Km/h" or more
