If the manual up and down function operates normally but the auto up and down function does not, then fail-safe mode may be functioning.
If power window initialization has not been performed, the auto up and down function will not operate.
If the rear power window regulator motor assembly LH has been replaced with a new one, initialize the power window control system.
Check that the "RL Window Auto Up" and "RL Window Auto Down" power window control system customize settings are "ON" before proceeding with work.
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.
If the pulse sensor built into the rear power window regulator motor assembly LH 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 LH at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly LH.
Using the GTS, read the data for the condition when the rear power window regulator switch assembly LH was operated.
