OCS Control Unit
WARNING: This page is about a different car, the 2016 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Always perform zero point reset using CONSULT when removing and installing the front passenger seat or servicing the occupant classification system (OCS). If zero point reset is not performed, the OCS may not operate normally, which may increase the risk of serious injury in a collision.
