Starter Control Relay
WARNING: This page is about a different car, the 2011 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
Starter control relay and starter relay are integrated in IPDM E/R. Both are used for the engine starting function. The starter relay is controlled by BCM, and the starter control relay is controlled by the IPDM E/R while both communicate with the BCM. IPDM E/R sends the starter control relay and starter relay status signal to BCM.
