SYSTEM BLOCK DIAGRAM

The base grade regulator (driver’s seat), the regulator other than for the base grade (driver’s and passenger’s seats) or regulators for models with telematics (all seats) are equipped with a control module that controls the operational speed. It is connected with the body integrated unit via LIN communication. Operation is performed using individual switches. Only the seat equipped with the control module uses PLS signals of motor for auto-reversing and controlling operational speed.

NOTE
1. INITIALIZATION BY POWER WINDOW SWITCH (DRIVER’S SIDE)

Perform registration when any of the following procedures are taken.

  • With the ignition switch ON, when a power window is rolled up/down and then the power supply is cut. (This is because the positional information is updated at the moment the power window is moved after the ignition switch is turned ON.)

  • When regulator or regulator motor is replaced. (Registration is not necessary when the battery is replaced.)

1.

Turn the ignition switch to ON.

2.

Operate the switch ‐ power window main in “DOWN” direction to fully open the driver’s side glass assembly ‐ front door. Once the window is fully opened, hold the switch for longer than one second.

 

Wherever the glass is at any position, operate the switch in “DOWN” direction.

3.

Operate the switch ‐ power window main in “UP” direction to fully close the glass assembly ‐ front door on the driver’s side. Once the window is fully closed, hold the switch for longer than one second.

 

At this time, do not move the vehicle.

4.

Operate the switch ‐ power window main in “AUTO DOWN” direction to check whether the window fully opens properly. Also, operate the switch in “AUTO UP” direction to check whether the window fully closed properly.

 

If the window does not fully open/close properly, repeat steps 1) to 4).

2. INITIALIZATION BY POWER WINDOW SWITCH (PASSENGER’S SIDE)

Perform registration when any of the following procedures are taken.

  • With the ignition switch ON, when a power window is rolled up/down and then the power supply is cut. (This is because the positional information is updated at the moment the power window is moved after the ignition switch is turned ON.)

  • When regulator or regulator motor is replaced. (Registration is not necessary when the battery is replaced.)

1.

Turn the ignition switch to ON.

2.

Operate the switch ‐ power window main or the switch ‐ power window on the passenger’s side in “DOWN” direction to fully open the glass assembly ‐ front door on the passenger’s side. Once the window is fully opened, hold the switch for longer than one second.

 

  • Wherever the glass is at any position, operate the switch in “DOWN” direction.

  • The operation can be done from both the switch ‐ power window main and the switch ‐ power window on the passenger’s side.

3.

Operate the switch ‐ power window main or the switch ‐ power window on the passenger’s side in “UP” direction to fully close the glass assembly ‐ front door on the passenger’s side. Once the window is fully closed, hold the switch for longer than one second.

 

At this time, do not move the vehicle.

4.

Operate the switch ‐ power window main or switch ‐ power window on passenger’s side in “AUTO DOWN” direction to check whether the window fully opens properly. Also, operate the switch in “AUTO UP” direction to check whether the window fully closed properly.

 

  • If the window does not fully open/close properly, repeat steps 1) to 4).

  • The operation can be done from both the switch ‐ power window main and the switch ‐ power window on the passenger’s side.

3. INITIALIZATION USING THE POWER WINDOW SWITCH (REAR SEAT)

Perform registration when any of the following procedures are taken.

  • With the ignition switch ON, when a power window is rolled up/down and then the power supply is cut. (This is because the positional information is updated at the moment the power window is moved after the ignition switch is turned ON.)

  • When regulator or regulator motor is replaced. (Registration is not necessary when the battery is replaced.)

1.

Turn the ignition switch to ON.

2.

Operate the switch ‐ power window main or the switch ‐ power window on the rear seat side in “DOWN” direction to fully open the glass assembly ‐ rear door on the rear seat side. Once the window is fully opened, hold the switch for longer than one second.

 

  • Wherever the glass is at any position, operate the switch in “DOWN” direction.

  • The operation can be done from both the switch ‐ power window main and the switch ‐ power window on the rear seat side.

3.

Operate the switch ‐ power window main or the switch ‐ power window on the rear seat side in “UP” direction to fully close the glass assembly ‐ rear door on the rear seat side. Once the window is fully closed, hold the switch for longer than one second.

 

At this time, do not move the vehicle.

4.

Operate the switch ‐ power window main or the switch ‐ power window on the rear seat side, and check that the speed of automatic rolling up and down of the windows changes.

 

  • If the window does not fully open/close properly, repeat steps 1) to 4).

  • The operation can be done from both the switch ‐ power window main and the switch ‐ power window on the rear seat side.

4. HOW TO RESET THE FULL OPEN STOP POSITION

When the full open stop position becomes misaligned, it can be reset by performing the following procedure.

1.

Turn the ignition switch to ON.

2.

Operate and hold the switch ‐ power window in “AUTO DOWN (front seat)” direction (fully push the switch) or in “DOWN (rear seat)” direction for three seconds or more.

 

For the driver’s side window, this operation can be done from the switch ‐ power window main, and for the passenger’s and the rear seat side window, this can be done from either the switch ‐ power window main or the switch ‐ power window on the passenger’s side or the rear seat side.

3.

Check that the glass starts rolling down and fully opens.

4.

Operate the switch ‐ power window in “AUTO UP (front seat)” or “UP (rear seat)” direction to check whether the window fully closes properly.

5. HOW TO RESET THE FULL CLOSE STOP POSITION

When the full close stop position becomes misaligned, it can be reset by performing the following procedure.

1.

Turn the ignition switch to ON.

2.

Operate and hold the switch ‐ power window in “AUTO UP (front seat)” direction (fully pull up the switch) or in “UP (rear seat)” direction for three seconds or more.

 

For the driver’s side window, this operation can be done from the switch ‐ power window main, and for the passenger’s and the rear seat side window, this can be done from either the switch ‐ power window main or the switch ‐ power window on the passenger’s side or the rear seat side.

3.

Check that the glass starts rolling up and fully closes.

4.

Operate the switch ‐ power window in “AUTO DOWN (front seat)” or “DOWN (rear seat)” direction to check whether the window fully opens properly.
