Toyota RAV4 Service Manual: Initialization
- Initialize sliding roof drive gear subassembly
Notice:
When replacing the sliding roof drive gear, the sliding roof drive gear requires initialization. If a reset is not executed, the following functions do not operate: auto operation and key off operation.
- Turn the ignition switch on.
- If the sliding roof is open, close it fully.
- By pushing the slide open switch of the slide switch or the up switch of the tilt switch on the personal light, make the sliding roof operate as follows: tilt up →approximately 1 second → tilt down → slide open → slide closed.
- Check that the sliding roof stops at the fully closed position.
- Finish the initialization.
- Check that the auto operation works normally.
Notice:
If the following conditions occur while operating, initialization will fail.
- Ignition switch is turned off.
- Pushed sliding roof control switch is released while sliding roof is operating.
- Vehicle speed is 5 km/h (3 mph) or more.
- Communication is cut off.
Hint:
- If the sliding roof cannot fully close or its position has become misaligned, perform the initialization again.
- If the sliding roof tilt up switch or slide close switch is pressed and held until the roof glass has either stopped moving or started moving in the opposite direction, and then the switch is held for another 10 seconds or more, perform the initialization again.
- If the auto operation function and jam protection function do not operate after the drive gear has been reset, replace the sliding roof drive gear (sliding roof ecu).
