Front Wiper Auto Stop Operation

WARNING: This page is about a different car, the 2018 Infiniti Q60. However, it is still accessible from the selected car via links, so may be relevant.

BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
IPDM E/R detects the front wiper stop position signal from the front wiper motor to find out the front wiper motor position (stop position/except stop position).
When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper motor returns to the stop position.
