    2.  

  36.  

Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.

  1. POWER WINDOW CONTROL SYSTEM (with jam protection function)
  2.  

Resetting the power window motors (initializing the pulse sensor) is necessary if: 1) the battery terminal is disconnected; 2) the power window regulator master switch, power window regulator switch, wire harness, power window regulator and power window motor are replaced or removed / installed; or 3) the GAUGE fuse, AM1 fuse, FL DOOR fuse and FR DOOR fuse are replaced. The AUTO operation function, jam protection function and remote operation function via the power window regulator master switch will not operate unless the motors are reset.

Be sure to reset the power window regulator motors using the power window switch on each door. The motors cannot be reset by remote operation through the power window master switch.

In order to prevent a large amount of current from being flowed into the system, do not simultaneously reset 2 or more power window regulator motors.

If the power window switch has been continuously operated for a long time, the power window regulator motor will stop so that no additional load can be applied to the motor. Continuing to operate the switch even after the motor has stopped will cause the switch to blink while restricting the AUTO UP / DOWN function and the remote UP/DOWN function. If this happens, reset the motor again after a few minutes have passed.

  1. Turn the ignition switch ON.
  2.  
  3. Halfway open the power window by pressing the power window switch.
  4.  
  5. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approximately 1 second after the power window is fully closed.
  6.  
  7. Check that the AUTO UP / DOWN function operates normally.
  8.  

If the AUTO/DOWN function operates normally, reset operations are complete. If not normal, perform the following 3 steps below.

  1. Disconnect the negative (-) battery terminal for 10 seconds.
  2.  
  3. Connect the battery terminal.
  4.  
  5. Perform the first 4 steps above.
  6.  

If the AUTO / DOWN function operates normally, reset operations are complete. If not normal, perform the following 4 steps below.

  1. Turn the ignition switch ON.
  2.  
  3. Halfway open the power window by pressing the power window switch.
  4.  
  5. Fully pull up the switch until the power window is fully closed and continue to hold the switch for approximately 12 seconds after the power window is fully closed.
  6.  
  7. Check that the AUTO UP / DOWN function operates normally.
  8.  
  9. SLIDING ROOF SYSTEM
  10.  

The drive gear (motor) must be reset (pulse sensor's location must be set) when one of the following occurs: 1) the battery cable has been disconnected from the negative (-) battery terminal, 2) the drive gear connector is connected /disconnected, or 3) the sliding roof is replaced or installed / removed. If the drive gear is not reset, the AUTO function will not operate.

  1. The sliding roof AUTO operation and the jam protection function may not operate normally if the battery cable is disconnected / reconnected, the battery replaced or recharged. Initialize the sliding roof system using the method below.
  2.  
  3. Turn the ignition switch ON.
  4.  
  5. Press the CLOSE switch to activate the close operation. Fully close the roof and continue to press the CLOSE switch for approximately 2 seconds. When the sliding roof control ECU initialization is finished, the roof will automatically open and stop a few millimeters from the fully open position.
  6.  

If the battery cable is disconnected, the sliding roof control ECU may not detect the position of the roof glass. If the sliding roof AUTO operation is still disabled even after the drive gear has been initialized, the Hall IC may be malfunctioning. The Hall IC is built into the drive gear and detects the roof glass position.

If the result is not as specified, replace the drive gear assembly (sliding roof control ECU).

  1. Check the SRS warning light.
    1. Check the SRS warning light.
    2.  
    3. Turn the ignition switch to the ON position, and check that the SRS warning light comes on for approximately 6 seconds (primary check).
    4.  
    5. Check that the SRS warning light goes off approximately 6 seconds after the ignition switch is turned to the ON position (constant check).

  10.  

The drive gear (motor) must be reset (pulse sensor's location must be set) when one of the following occurs: 1) the battery cable has been disconnected from the negative (-) battery terminal, 2) the drive gear connector is connected /disconnected, or 3) the sliding roof is replaced or installed / removed. If the drive gear is not reset, the AUTO function will not operate.

  1. The sliding roof AUTO operation and the jam protection function may not operate normally if the battery cable is disconnected / reconnected, the battery replaced or recharged. Initialize the sliding roof system using the method below.
  2.  
  3. Turn the ignition switch ON.
  4.  
  5. Press the CLOSE switch to activate the close operation. Fully close the roof and continue to press the CLOSE switch for approximately 2 seconds. When the sliding roof control ECU initialization is finished, the roof will automatically open and stop a few millimeters from the fully open position.
  6.  

If the battery cable is disconnected, the sliding roof control ECU may not detect the position of the roof glass. If the sliding roof AUTO operation is still disabled even after the drive gear has been initialized, the Hall IC may be malfunctioning. The Hall IC is built into the drive gear and detects the roof glass position.

If the result is not as specified, replace the drive gear assembly (sliding roof control ECU).
