INSPECTION PROCEDURE

NOTICE:
When the sliding roof drive gear sub-assembly is removed and reinstalled or replaced, the sliding roof drive gear sub-assembly must be initialized (LandCruiser RM000001VJR08IX.html).
1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (SLIDING ROOF)

  1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the sliding roof slides open/closed and tilts up/down (LandCruiser RM000000UZR094X.html).
