The repair of this fault centers on verifying the integrity of the sensor’s internal circuitry and software validity. Refer to the enclosed graphic as a reference of specific Side Impact Satellite Acceleration, Side Impact Satellite Pressure, and Up-Front Satellite Acceleration sensor locations on the vehicle.
