Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Side Impact Sensor
Four side impact sensors (1) are used on this vehicle when it is equipped with side curtain airbags, two each for the left and right sides of the vehicle. These sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller (ORC). Each side sensor is secured with two screws to the inner right or left B-pillar and C-pillar beneath the trim within the passenger compartment. The sensor housing has an integral connector receptacle (2), an integral anti-rotation pin (3), and two integral mounting holes (4) with metal sleeves to provide crush protection.
The right and left side impact sensors are identical in construction and calibration. A label on the sensor is imprinted with an arrow, which should always be pointed outboard in the vehicle. A cavity in the center of the molded plastic impact sensor housing contains the electronic circuitry of the sensor which includes an electronic communication chip and an electronic impact sensor. Potting material fills the cavity and a stamped cover (5) is crimped over the cavity to seal and protect the internal electronic circuitry and components. The side impact sensors are each connected to the vehicle electrical system through a dedicated take out and connector of the body wire harness.
The impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
