SSOFF Relay
WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
The SSOFF (self shutoff) relay supplies power to VCM and the coil of the A/C relay. The SSOFF relay is controlled by VCM so that VCM can shut off VCM power (self shutoff).
