Sensor Replacement Guidelines

The SIR sensor replacement policy requires replacing the sensors in the area of accident damage. The area of accident damage is defined as the portion of the vehicle that is crushed, bent, or damaged due to a collision. If the vehicle has a SIR sensor mounted forward of the radiator, replace the SIR sensor.
^ Replace the sensor even if the air bags have not deployed.
^ Replace the sensor even if the sensor appears to be undamaged.

Sensor damage which is not visible, such as slight bending of the mounting bracket or cuts in the wire insulation, may cause improper operation of the SIR sensing system. Do not try to determine whether the sensor is undamaged, replace the sensor. Also, replace the sensor if a Diagnostic Trouble Code (DTC) table indicates a malfunctioning sensor.
