Inspection procedure
- Check sliding roof function
- Check the auto operation with the slide open and tilt up switch (see page rf-9).
Ok: auto operation operates normally with slide open and tilt up switch.
- Delete dtc
- Delete the dtc (see page rf-7).
End
- Initialize sliding roof drive gear sub-assembly (sliding roof ecu)
- Check that the sliding roof drive gear can be initialized (see page rf-4).
Ok: sliding roof drive gear can be initialized.
- Check sliding roof function
