CAUTION / NOTICE / HINT
NOTICE:
-
If the rear power window regulator motor assembly RH has been replaced with a new one, initialize the power window control system (See page

Check that the "RR Window Auto Up" and "RR Window Auto Down" power window control system customize settings are "ON" before proceeding with work (See page
).
- After the catch protection function operates, the auto operation is not performed the first time auto up is performed. All auto up operations performed after the first operate normally.
HINT:
If the pulse sensor built into the rear power window regulator motor assembly RH is malfunctioning, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the rear power window regulator switch assembly RH at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly RH (See page
