INITIALIZATION INITIALIZE SLIDING ROOF SYSTEM
NOTICE:
- When the sliding roof glass sub-assembly or sliding roof drive cable
sub-assembly is adjusted or removed/installed, or the sliding roof drive
gear sub-assembly is replaced, the sliding roof ECU (sliding roof drive
gear assembly) must be initialized to store the position of the sliding
roof. If initialization is not performed, the auto operation function,
jam protection function, key-off operation function, key-linked
function, wireless transmitter-linked function and sliding roof open
warning function may not operate, or the sliding roof may move in
reverse or become misaligned.
- During initialization, do not subject the vehicle to physical shock,
such as opening/closing a door or driving the vehicle at 5 km/h (3 mph)
or more, and do not perform any electrical operations.
- Make sure not to turn the power switch on (ACC) or off during initialization.
- If the sliding roof ECU (sliding roof drive gear assembly) has been
replaced, DTC B2343 will be stored. Clear the DTC after performing
initialization.

HINT:
- The sliding roof switch is built into the roof console box sub-assembly.
- It is not necessary to initialize the sliding roof ECU (sliding roof
drive gear assembly) if the cable has been disconnected from the
negative (-) auxiliary battery terminal, or if the auxiliary battery has
been replaced.
(a) Perform initialization according to the table below. |
Condition of Sliding Roof |
Proceed to | | Auto operation function does not operate. |
Procedure A | | Auto
operation function operates, but the sliding roof does not stop at the
correct position (misalignment occurs), or the sliding roof moves in the
opposite direction during tilt down operation. |
Procedure B | | Auto operation function operates, but the sliding roof moves in the opposite direction during slide close operation. |
Procedure C | (1) Procedure A
- Turn the power switch on (IG).
- Fully close the sliding roof and release the sliding roof switch (roof console box sub-assembly).*1
- Press and hold the CLOSE or UP switch.
- The sliding roof performs the following operations: tilt up → pause for 1 second → tilt down → slide open → slide closed.
- After the sliding roof stops in the fully closed position, release the switch.*2
NOTICE:
Press
and hold the CLOSE or UP switch until *2 is completed. If the switch is
released before *2 is completed, repeat the operation from *1.
HINT:
The initialization process ends when this operation is complete.
- Make sure that the sliding roof auto operation function operates normally.
(2) Procedure B
- Turn the power switch on (IG).
- Press the UP switch to move the sliding roof to the fully tilted up position and then release the UP switch.
HINT:
- If the sliding roof cannot be fully tilted up due to misalignment of the
sliding roof glass sub-assembly, press and hold the CLOSE switch until
the sliding roof stops closing, and then press and hold the UP switch
until the sliding roof stops tilting up.
- If the sliding roof moves in the opposite direction while it is being
closed, repeatedly tap the CLOSE switch at short intervals to fully
close the sliding roof. When the sliding roof is fully closed, press the
UP switch to move the sliding roof to the fully tilted up position.
- Press and hold the UP switch again until the sliding roof completes the
following operations: pause for approximately 10 seconds or more → tilt
inching motion → pause for 1 second → tilt down → slide open → slide
closed.*1
- After the sliding roof stops in the fully closed position, release the switch.*2
NOTICE:
- While performing *1, if the UP switch is released before "pause for
approximately 10 seconds or more" completes, start this step over.
- While performing *1, if the UP switch is released after "pause for
approximately 10 seconds or more" completes, but before the above
movements complete, perform procedure A to initialize the position of
the sliding roof.
- Press and hold the UP switch until *2 is completed.
HINT:
The initialization process ends when this operation is complete.
- Make sure that the sliding roof auto operation function operates normally.
(3) Procedure C
- Turn the power switch on (IG).
- Press and hold the CLOSE switch until the sliding roof completes the
following operations: slide closed → move in the opposite direction →
pause for approximately 10 seconds or more → slide closed → tilt up →
pause for 1 second → tilts down → slide open → slide closed.*1
- After the sliding roof stops in the fully closed position, release the switch.*2
NOTICE:
- While performing *1, if the CLOSE switch is released before "pause for
approximately 10 seconds or more" completes, start this step over.
- While performing *1, if the CLOSE switch is released after "pause for
approximately 10 seconds or more" completes, but before the above
movements complete, perform procedure A to initialize the position of
the sliding roof.
- Press and hold the CLOSE switch until *2 is completed.
HINT:
The initialization process ends when this operation is complete.
- Make sure that the sliding roof auto operation function operates normally.
