Sub Battery Relay

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.

The sub battery relay is controlled by EMCM. The sub battery relay connects/interrupts the circuit between the main battery power supply circuit and the sub battery power supply circuit.
