Assist Door Module
ASSIST DOOR MODULEDESCRIPTION
Assist power window switch, a component of CAN, performs CAN communication with BCM, seat ECU, tilt ECU, driver power window switch and PIC module, and it also performs LIN communication with switch module and safety ECU. Passenger controls assist power window switch button located inside of the assist door to operate power window, mirror, door lock and unlock.
1. It performs 4 types of operation of manual up/down and automatic up/down operation for 4 power windows.
2. It performs manual operation of the mirror position by manual switch, (up/down and left/right)
3. It performs registration and replay of mirror position by the mirror switch up to 2 drivers.
FUNCTION
POWER WINDOW CONTROL
1. This switch controls power window up/down, automatic up/down from assist side. Assist's power window switch sends input signal through LIN communication by the manual up/down and automatic up/down switch input. At the same time manual up/down and automatic up/down signals sends to the wires
- Assist safety window ECU receives the signal and performs manual up/down and automatic up/down functions.
2. 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.
OUTSIDE MIRROR CONTROL BY THE SWITCH
1. Manual control of right outside mirror
If the mirror direction switch (up, down, left and right) is pressed when mirror selection switch on driver power window switch is in outside RH under ACC ON condition, then operating signal is sent to assist power window switch through CAN communication.
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.
- After 5 seconds elapse from memory switch ON.
- When the ignition 2 is OFF
- When the memory stop switch is ON
- When memory registration is complete
3. If more than 2 switches are pressed simultaneously between memory switch and position switches (POS1 or POS2), input is ignored. (Switch module sends in LIN communication)
4. Memory registration cannot be performed if the vehicle speed is over the speed limit or shift lever is not in " P" while the parking brake is released.
5. Memory is cleared if the battery is removed.
OUTSIDE MIRROR REPLAY OPERATION BY THE MEMORY SWITCH
1. Mirror is returned to the registered position as each position switch is pressed while the ignition 2 is ON.
2. Memory replay operation will be performed only if the memory is registered.(POS1 or POS2)
3. If the position switch (POS1 or POS2) is pressed while the memory replay is in operation, the final switch is effective.
4. Replay inhibit condition
- When inhibit " P" switch is OFF
- When the ignition 2 is OFF
- When RH side mirror switch is pressed
- When the vehicle speed is more than 3 km/h
- When the memory STOP switch is turned ON
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
- 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 3 km/h
- When the memory stop switch is ON
