CAUTION / NOTICE / HINT
NOTICE:
- If the front power window regulator motor assembly RH has been replaced
with a new one, initialize the power window control system (See page
).
- Check that the "P Window Auto Up" and "P 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 front 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 power window regulator
switch assembly at the auto up position, and opened manually by pushing down the
power window regulator switch assembly (See page
).
