SLIDING ROOF / CONVERTIBLE: SLIDING ROOF SYSTEM: INITIALIZATION

1. INITIALIZE SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)

NOTICE:
* When the sliding roof glass, sliding roof housing or sliding roof ECU (sliding roof drive gear sub-assembly) is replaced or removed and installed, the sliding roof drive gear requires initialization (pulse sensor initial position setting), as the glass position cannot be determined. If initialization is not performed, the auto slide open and tilt up functions, key-off operation and jam protection function may not operate, or the sliding roof may move in reverse or become misaligned.
* During initialization, do not apply a physical shock, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, to the vehicle and do not perform the electrical operations:

HINT
When the cable of the negative (-) battery terminal is disconnected and reconnected or the drive gear connector is disconnected and reconnected, sliding roof drive gear (pulse sensor initial position setting) initialization is not necessary.

(a) Perform initialization according to the table below.





HINT
Before performing initialization, make sure that there is no foreign matter on the guide rails and the guide rails are not deformed.

(1) Procedure A

Turn the power switch on (IG).

Press and hold the OPEN switch.

NOTICE:
Make sure not to release the switch during the initialization. If the switch is released, perform the initialization again.

The sliding roof glass starts open operation (tilt up and slide open operation) and stops at the fully open position.

After the sliding roof glass stops, check that the sliding roof glass moves slightly forward and stops at the correct fully open position.

HINT
The initialization process ends when this operation completes.

(2) Procedure B

Turn the power switch on (IG).

Press and hold the CLOSE switch until the following movements finish: starts close operation (slide close or tilt down operation) -> erroneously reverses -> stops operation for 10 seconds -> starts close operation (slide close or tilt down operation) -> stops at the fully closed position.

NOTICE:
* If the switch is released before "stops operation for 10 seconds" finished, perform Procedure B again.
* If the switch is released after "stops operation for 10 seconds" finished, perform Procedure A.

Perform Procedure A.

(3) Procedure C

Turn the power switch on (IG).

Press and hold the OPEN switch until the following movements finish: starts slide open operation -> stops at the incorrect fully open position for 10 seconds -> stops at the fully open position.

NOTICE:
* If the switch is released before "stops at the incorrect fully open position for 10 seconds" finished, perform Procedure C again.
* If the switch is released after "stops at the incorrect fully open position for 10 seconds" finished, perform Procedure A.

After the sliding roof glass stops, check that the sliding roof glass moves slightly forward and stops at the correct fully open position.

HINT
The initialization process ends when this operation completes.
