SLIDING ROOF / CONVERTIBLE: SLIDING ROOF SYSTEM: INITIALIZATION

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

NOTICE:
* Before starting this operation, make sure that the guide rails are not deformed and there are no foreign objects on the guide rails.
* When the sliding roof glass, sliding roof housing or sliding roof drive gear sub-assembly (sliding roof ECU) 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 to the vehicle, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, and do not perform the following electrical operations:
(a) Cranking the engine
(b) Turning the ignition switch from ON to off
(c) Operating the power window switches
(d) Operating the window defogger switch
(e) Operating the blower switch
(f) Locking/unlocking a door
(g) Operating the headlight dimmer switch

HINT
When the cable of the negative (-) battery terminal is disconnected and reconnected or the sliding roof 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.





(1) Procedure A

1 Turn the ignition switch to ON.

2 Press and hold the CLOSE switch.

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

3 The sliding roof glass starts the close operation (tilt down and slide close operation) and stops at the fully close position.

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

HINT
The initialization process ends when this operation completes.

(2) Procedure B

1 Turn the ignition switch to ON.

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

3 The sliding roof glass starts the close operation (tilt down and slide close operation) and stops at the fully close position.

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

HINT
The initialization process ends when this operation completes.

(3) Procedure C

1 Turn the ignition switch to ON.

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

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

HINT
The initialization process ends when this operation completes.
