Toyota Venza: Initialization

NOTICE:

• When the sliding roof glass, sliding roof housing or sliding roof ECU (sliding roof drive gear sub-assembly) 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 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, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, to the vehicle and do not perform the following electrical operations:
  1. Cranking the engine
  2. Turning the ignition switch from ON to off
  3. Operating the power window switches
  4. Operating the window defogger switch
  5. Operating the blower switch
  6. Locking/Unlocking a door
  7. Operating the headlight dimmer switch

1. Turn the ignition switch to ON.
2. Press and hold the SLIDE CLOSE or TILT DOWN switch.

   NOTICE:

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

3. The sliding roof glass starts sliding close operation and stops at the fully closed position.
4. After the sliding roof glass stops, check that the sliding roof glass moves again and stops at the correct fully closed position.

   HINT:

   The initialization process ends when this operation completes.
