System Description

WARNING: This page is about a different car, the 2010 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.

CAUTION: IPDM E/R integrated relays cannot be removed.
