WARNING: This page is about a different car, the 2013 Infiniti M56 and 2013 Infiniti M37. However, it is still accessible from the selected car via links, so may be relevant.

Transfer fluid temperature sensor is integrated with electric controlled coupling.
Transfer fluid temperature sensor detects the transfer fluid temperature and transmits a signal to AWD control unit.
