SIDE IMPACT SENSOR

    The side impact sensors are installed in the bottom sections of the right and left center pillars. Each sensor incorporates an analog G-sensor, micro computer, and other electrical parts. The micro computer always monitors the analog G-sensor’s output. If the micro computer determines that deployment of the side air bag is required, it sends a signal to the SRS-ECU, requesting ignition of the air bag inflator.
The micro computer also performs diagnosis of the side impact sensor components. If any fault is detected, the micro computer sends the corresponding diagnosis code to the SRS-ECU.
