Initialization

INITIALIZATION






NOTE: When disconnect the negative (-) battery terminal, initialize the following system(s) after the terminal is reconnected.

1. RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR

NOTE:
- 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.

a. Turn the ignition switch ON.
b. Halfway open the power window by pressing the power window switch.
c. 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.
d. Check that the AUTO UP/DOWN function operates normally.

If the AUTO/DOWN function operates normally, reset operations are complete. If not normal, follow steps (e) to (g) below.

e. Disconnect the negative (-) battery terminal for 10 seconds.
f. Connect the battery terminal.
g. Perform steps (a) to (d) again.

If the AUTO/DOWN function operates normally, reset operations are complete. If not normal, proceed to steps (h) to (k) below.

h. Turn the ignition switch ON.
i. Halfway open the power window by pressing the power window switch.
j. 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.
k. Check that the AUTO UP/DOWN function operates normally.

2. RESET SLIDING ROOF DRIVE GEAR (MOTOR)

NOTE: The sliding roof drive gear (motor) must be reset (pulse sensor's location must be set) when: 1) the battery has been disconnected, 2) the drive gear connection 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.

a. The sliding roof AUTO operation and the jam protection function may not operate normally if the battery is disconnected/reconnected, replaced or recharged. Initialize the sliding roof system using the method below.
1. Turn the ignition switch ON.
2. 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.

HINT: If the battery terminal 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 sliding roof drive gear has been initialized, the hall IC may be malfunctioning. The hall IC is built into the sliding roof drive gear and detects the roof glass position.

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

3. INSPECT SLIDING ROOF FUNCTION

HINT:
- If the jam protection function is not operating, reset the drive gear again.
- If the AUTO operation function and jam protection function do not operate after the driver gear has been reset, replace the sliding roof driver gear (sliding roof control ECU).
