INITIALIZE SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR ASSEMBLY)
When the sliding roof ECU (sliding roof drive gear assembly) is replaced or removed and reinstalled, it requires initialization. If initialization is not performed, the following functions may not operate, or may not operate correctly: auto operation and jam protection function.
If the following conditions occur during the initialization procedure, initialization will fail:
One of the following electric loads is applied to the vehicle during initialization: cranking the engine, power window operation, rear defogger operation, blower operation, power seat operation, power door lock operation or headlight illumination.
The engine switch is turned off.
Another switch is turned on during initialization.
The vehicle experiences a strong vibration during initialization, such as slamming of a door.
Check the operation of the sliding roof.
| Sliding Roof Operation | Proceed to |
|---|---|
| Auto operation does not operate. | Procedure A |
| Auto operation operates normally, but the sliding roof glass does not stop at the correct fully closed position. | Procedure B |
| Auto operation operates normally, but the sliding roof erroneously reverses operation while sliding closed. | Procedure C |
Before performing initialization, make sure that there is no foreign matter on the guide rails and the guide rails are not deformed.
Procedure A (Normal initialization)
Turn the engine switch on (IG).
Press and hold the CLOSE switch.
The sliding roof glass starts sliding close operation and stops at the fully closed position.
After the sliding roof glass stops, continue pressing the CLOSE switch for 1 second or more.
Check that the sliding roof glass moves slightly rearward and stops at the correct fully closed position.
The initialization process ends when this operation completes.
Procedure B (Resetting the memorized position)
Turn the engine switch on (IG).
Press and hold the CLOSE switch until the sliding roof glass stops and then release the switch.
Press and hold the CLOSE switch again for 10 seconds or more.
The sliding roof glass starts sliding closed operation and stops at the fully closed position.
After the sliding roof glass stops, continue pressing the CLOSE switch for 1second or more.
Check that the sliding roof glass moves slightly rearward and stops at the correct fully closed position.
The initialization process ends when this operation completes.
Procedure C (Clear initialization)
Turn the engine switch on (IG).
Press and hold the CLOSE switch until the following movements finish and then release the switch: starts sliding closed → erroneously reverses → stops operation for 10 seconds → starts sliding closed → stops at the fully closed position.
Perform Procedure A.
