Crash Zone Sensor
WARNING: This page is about a different car, the 2016 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
The crash zone sensor is located infront of the radiator. The crash zone sensor sends signals to the air bag diagnosis sensor unit during a frontal collision. This sensor may be identified by a yellow connector.
