Driver Door Module (DDM)





Description

The driver door module is a part of a Controller Area Network (CAN), and performs CAN communication with the FAM, IPM, ADM, and IMS. 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. Opening and closing the quarter glass by the quarter glass switch.
3. Window UP/DOWN operation.
4. Manually operating the mirror position by the manual switch (Up, Down, Right, and Left)
5. Saving and replacing the mirror position by the MEMORY switch -> For 2 persons
6. Out side mirror AUTO reverse operation
7. Out side mirror FOLD/UNFOLD power control
8. CENTRAL DOOR LOCK/UNLOCK function
9. Illumination control

Control Function

Power Window Control
1. This switch controls power window up/down, automatic up/down from driver & assist side.
A. Driver's power window switch sends input signal through CAN communication by the manual up/down and automatic up/down switch input. At the same time passenger side sends manual up/down and automatic up/down signals to the wires.
B. Each safety window ECU receives the signal and performs manual up/down and automatic up/down functions.
2. Power window lock
When the driver's power window lock switch is ON, each safety window ECU receives the power window lock command to prohibit the operation by the passenger side doors except the driver's door.
3. Timer function
Power window switch can be controlled for 30 seconds after the ignition is turned off. This function stops immediately even within 30 seconds if the front door is opened.

Key Reminder
1. 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 and there will be a series of three output signals every 0.5sec if door condition is "Lock".
2. Remained action goes on though Key Reminder Unlock message changes to "OFF".

Priority Of Door Lock/unlock
1. Higher priority signals take precedence, and will override lower priority signals.
2. If the priority is the same or low, it'll be ignored.

Out Side Mirror Control By The Switch
1. If the mirror direction switch (up, down, left and right) is pressed when mirror selection switch on driver side power window switch is in outside LH(RH) under ACC ON condition, then mirror motor moves to the corresponding direction.

Outside Mirror Memory Operation By The Memory Switch
1. If position switch (POS1 or POS2) is pressed within 5 seconds after pressing the memory switch under ignition 2 on, it registers current mirror position. (Memory permit status lasts for 5 seconds after memory switch ON. After 5 seconds, memory permits status terminates. In other words, current position is registered if the position switch (POS1 or POS2) is turned on, during the memory permit status). However, RH side mirror position is not registered during the LH side mirror manual switch operation.
2. Memory permit status is released if any of the following conditions is met
A. If 5 seconds is elapsed after the memory switch is turned on
B. If the ignition 2 is turned off
C. When saving is completed
D. If Ignition switch of the CAN communication data sent by the IPM is not "Run" or "Start".
E. If Inhibit switch of the CAN communication data sent by the FAM is not "P".
F. If vehicle speed of the CAN communication data sent by the cluster is "3Km/h" or more.
3. Memory is cleared if the battery is removed.

Outside Mirror Memory And Replay Operation By Keyless
1. Memory operation
A. Outside mirror LH position is registered in the driver side power window switch when the ignition is turned off from on.
2. Replay prohibit condition
A. If the mirror switch on the LH side is pressed
B. If Ignition switch of the CAN communication data sent by the IPM is not "Run" or "Start".
C. If Inhibit switch of the CAN communication data sent by the IPM is not "P".
D. If vehicle speed of the CAN communication data sent by the CLUSTER is "3Km/h" or more.
Auto Reverse Function






Fail Safe Function
1. If the sensor does not move more than 60mV for the input changes (5 second operation) of the position sensor although the motor is operating, automatic control will stop.
2. The mirror operation signal cannot be displayed into the same direction for more than 15 seconds. (When the mirror is replacing to the saved position or the switch is manually pressed)
3. Monitoring the replacing time
A. If the replacing operation does not stop within 40 seconds, the mirror motor will not outputted and the replacing operation will stop.

IMS Switch
1. If it's satisfied with the followings
(1) Can communication Data ignition switch sent by IPM is "RUN"
(2) Can communication Data Inhibit switch sent by IPM is "P"
(3) Can communication Data vehicle speed sent by CLUSTER is under "3Km/h"
2. If SET switch is ON, IMS message is SET.
3. If POSITION switch is ON within 5sec since SET switch is ON, IMS message will be sent to MEMORY1 or MEMORY2.

Seat Manual Switch
If Seat switch is controlled, seat control message is sent to seat.
