Circuit Operation

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

The SRS-ECU judges how severe a collision is by detecting signals from the front impact sensors and the G-sensor in the SRS-ECU. If the impact is over a predetermined level, the SRS-ECU sends an ignition signal. At this time, the lap pre-tensioner will deploy.
