Theory Of Operation
Impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the module. 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. It is important to review this graphic thoroughly to understand the specific area of diagnosis you are looking to complete.
The Up-Front Right and Up-Front Left Satellite Acceleration Sensors are located behind the Front End Module carrier in the engine area. The number 1 side sensors are located in the 1st row door area with the number 1 side sensor being on the passenger side (Right Side Satellite Pressure Sensor 1) and the number 1 side sensor also being on the driver side (Left Side Satellite Pressure Sensor 1). The number 4 side sensors are located in the "B" pillar area just past the 1st row doors (these side sensors will be new side sensors to be added for the 2011 model year). The number 4 side sensor is located on the passenger side (Right Side Satellite Acceleration Sensor 4) and the number 4 side sensor is also located on the driver side (Left Side Satellite Acceleration Sensor 4). The number 2 side sensors are located in the "C" pillar area just past the 2nd row doors. The number 2 side sensor is located on the passenger side (Right Side Satellite Acceleration Sensor 2) and the number 2 side sensor is also located on the driver side (Left Side Satellite Acceleration Sensor 2). The number 3 side sensors are located in the 3rd row area just above the rear axle. The number 3 side sensor is located on the passenger side (Right Side Satellite Acceleration Sensor 3) and the number 3 side sensor is also located on the driver side (Left Side Satellite Acceleration Sensor 3).
