Multiplex Communication: Overview Kia Sedona II

DESCRIPTION

The driver door module is a part of a Controller Area Network (CAN), and performs CAN communication with the BCM, FAM, IPM, RAM, 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 by RKE.
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. Saving and replacing the mirror position by RKE --> For 2 persons
7. Out side mirror AUTO reverse operation
8. Out side mirror FOLD/UNFOLD power control
9. CENTRAL DOOR LOCK/UNLOCK function
10. DOOR COURTESY LAMP control
11. Out side mirror DEFOG control
12. Illumination control

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. (Switch module sends in LIN communication). (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 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 switch of the CAN communication data sent by the IPM is not "Run" or "Start". If Inhibit switch of the CAN communication data sent by the FAM is not "P". 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 Outside mirror LH position is registered in the driver side power window switch when the ignition is turned off from on. When door is locked by the keyless, outside mirror position is registered corresponding to the keyless code. Data related to the memory operation is received from BCM in CAN communication.
2. Replay operation When door is unlocked by the keyless under ignition off state, it replays the position corresponding to the keyless code. Data related to the replay operation is received from BCM in CAN communication on CAN line.
3. Replay prohibit condition If the mirror switch on the LH side is pressed If Ignition switch of the CAN communication data sent by the IPM is not "Run" or "Start". If Inhibit switch of the CAN communication data sent by the FAM is not "P". If vehicle speed of the CAN communication data sent by the CLUSTER is "3Km/h" or more.

1. Memory operation Outside mirror LH position is registered in the driver side power window switch when the ignition is turned off from on. When door is locked by the keyless, outside mirror position is registered corresponding to the keyless code. Data related to the memory operation is received from BCM in CAN communication.
2. Replay operation When door is unlocked by the keyless under ignition off state, it replays the position corresponding to the keyless code. Data related to the replay operation is received from BCM in CAN communication on CAN line.
3. Replay prohibit condition When the inhibit "P" switch is OFF. When RH side mirror switch is pressed. When mirror switch is pressed after ignition on. When the vehicle speed is over 3km/h

The assist door module is a part of CAN, and performs CAN communication with the BCM, FAM, IPM, RAM, DDM, and IMS. The driver can control the power window, mirror, door (lock/unlock) by using buttons of the ADM on the door of the driver's seat.

1. Operating the power window by buttons
2. Central Door LOCK/UNLOCK function
3. Manually operating the mirror position by the manual SW (Up, Down, Right, and Left)
4. Saving and replacing the mirror position by the memory switch --> For 2 persons
5. Out side mirror AUTO reverse operation
6. Door courtesy lamp control
7. Out side mirror defog control
8. Illumination control

1. IMS Message from DDM is sent to RETURN1 or RETURN2, out side mirror returns to the position stored.
2. Memory permit status is released if any of the following conditions is met 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 switch of the CAN communication data sent by the IPM is not "Run" or "Start". If Inhibit switch of the CAN communication data sent by the FAM is not "P". 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 THE MEMORY SWITCH

1. IMS message from DDM is sent to RETURN1 or RETURN2, O/S MIRROR returns to the position stored.
2. Replacing not stored position doesn't work.
3. If RETURN Message is sent during replacing, the last Message has priority.
4. Replacing Prohibition Conditions.

1. If the mirror switch on the LH side is pressed
2. If Ignition switch of the CAN communication data sent by the IPM is not "Run".
3. If Inhibit switch of the CAN communication data sent by the FAM is not "P".
4. If vehicle speed of the CAN communication data sent by the CLUSTER is "3Km/h".

1. Memory operation If the ignition is turned off after being on, the position of the O/S mirror RH is saved in the switch ASSY power window main. If the door was keyless-locked, the outside mirror RH position is saved corresponding to the keyless code.
2. Replay operation If the door is keyless-unlocked while the IGN SW is off, replacing is made to the saved position corresponding to the keyless code.
3. Replay prohibit condition When the inhibit "P" switch is OFF When RH side mirror switch is pressed When mirror switch is pressed after ignition on When the vehicle speed is over 3km/h
