Sensor Replacement Guidelines

The Side Impact Sensor (SIS) replacement policy requires replacing sensors in the area of accident damage. The area of accident damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision. In this case, a moderate collision where the side of the vehicle, near the B-pillar, is crushed, bent, or damaged due to a collision, requires replacement of the sensor. The sensor must be replaced whether the curtain air bag has deployed or if the sensor seems to be undamaged. Sensor damage which is not visible, such as a slight bending of the mounting bracket or cuts in the wire insulation, can cause improper operation of the sensor. Do not try to determine whether the sensor is undamaged; replace the sensor. Also, if you follow a diagnostic trouble code (DTC) table and a malfunctioning sensor is indicated, replace the sensor.
