Side Impact Sensors
Side Impact Sensor
The side impact crash sensors must be fitted in the correct orientation, and there must be no gap between the sensor and the body mounting position. Ensure the mounting screws are tightened to the correct torque. Be careful when refitting trim molding not to damage sensors or sensor harness.
The side impact sensors are located behind the rear lower quarter trim moldings, and mounted to the body floor via their own mounting brackets, in alignment with the rear seat cushion front mountings. Each sensor is attached to their body mounting bracket by two Torx bolts.
Each side impact sensor consists of an electronic accelerometer, microprocessor and serial link circuit. The sensor uses the accelerometer to determine the severity of a side impact, and if the impact is great enough to warrant multiple restraint operation, the sensor communicates the need for deployment to the MRS control unit via a single line serial link.
