INITIALIZE ROOF SUNSHADE (for LONG TYPE PANORAMIC FIXED MOONROOF)
When the sunshade trim sub-assembly is adjusted or removed/installed, or the roof sunshade ECU (sliding roof drive gear sub-assembly) is replaced, the known roof sunshade position is lost. If initialization has not been performed, the position of the roof sunshade will deviate and the auto-operation function and jam protection function will not operate. For this reason, it is necessary perform initialization (pulse sensor initial position setting) of the roof sunshade ECU (sliding roof drive gear sub-assembly).
When performing initialization, do not add electrical load or cause large vehicle movement such as when opening or closing a door, or driving the vehicle (a vehicle speed signal of 5 km/h or more), etc.
The roof sunshade switch is located in the map light assembly.
Initialization
Refer to the following table and perform initialization.
| Roof Sunshade Condition | Link |
|---|---|
| Auto-operation does not operate. | Procedure A |
| Auto-operation operates normally but the roof sunshade position has deviated, etc. | Procedure B |
| Auto-operation operates, but incorrectly reverses during closing. | Procedure B |
Procedure A
Turn the ignition switch to ON.
Press and hold the CLOSE switch until the following operation is completed.
The roof sunshade moves in the following order: stopped for approximately 10 seconds*1 → starts closing → stops at the fully closed lock position → starts opening*2 → stops at the correct fully closed position (completion of initialization).
If the OPEN switch is released before initialization completes, press and hold the switch again until this operation completes.
*1: If the roof sunshade does not start closing after pausing for approximately 10 seconds, release and then press and hold the CLOSE switch until the operation is complete.
*2: The opening operation may not be noticeable as the opening distance is quite short.
Confirm that the roof sunshade auto function operates normally.
Procedure B
Turn the ignition switch to ON.
Press and hold the CLOSE switch for 0.3 seconds or more to start the roof sunshade auto function.
Press and hold the CLOSE switch until the following operation is completed.
The roof sunshade moves in the following order: stopped for approximately 10 seconds*1 → starts closing → stops at the fully closed lock position → starts opening*2 → stops at the correct fully closed position (completion of initialization).
If the OPEN switch is released before the initialization completes, turn the ignition switch off and perform procedure B again.
*1: If a close operation is not performed after being stopped for approximately 10 seconds, release the CLOSE switch, then press and hold the CLOSE switch again until the operation completes.
*2: The opening operation may not be noticeable as the opening distance is quite short.
Confirm that the roof sunshade auto function operates normally.
