Ford Freestar Air Bag Sensor Parts and Q&A

• Impact Sensor, Front

  Q: What Precautions Should Be Taken When Servicing the Front Air Bag Sensor on Ford Freestar?

  A:

  Safety glasses should be worn at all times during service of the front impact severity sensor to protect against possible deployment-related injuries. Proper operation of the system requires the vehicle sensor to maintain correct orientation. It is mandatory to inspect the sensor bracket and wiring pigtail for deformation after a crash event before you replace or repose the sensor alongside all damaged supplemental restraint system parts regardless of Air Bag deployment. When the restraints control module fuse is detached while the Ignition Switch shows the ON position the air bag warning lamp lights up normally despite the absence of any fault. A vehicle cannot return to the customer until the supplemental restraint system operates with no faults present. The correct repair method consists of adding a new component; the diagnostic procedure needs to be repeated when the same issue occurs after reinstalling the original part. The first step involves turning off the system power followed by disconnecting the electrical connector of the front impact severity sensor. You should remove the two retaining nuts while making sure they reach 12 Nm (9 lb-ft) torque before reinstallation. The front impact severity sensor must be carefully taken out while checking both the radiator support and sensor mating components for cleanliness and absence of debris. The installation process ends after reversing the removal procedure and restarting the system power.
• Side Impact Sensor

  Q: How should the Air Bag Sensor for side impact in the second row on the left-hand side be serviced on Ford Freestar?

  A:

  The repair of the side impact sensor that sits in the left second row demands safety eye protection plus the elimination of memory saver equipment while the vehicle is in service. The RCM fuse removal will trigger the air bag warning lamp when the ignition switch activates ON position but this condition indicates normal operation without causing SRS fault issues. The vehicle needs to be returned to the customer only after verifying that the SRS operates correctly without any problems. The diagnostic process requires replacing the new component but if the problem continues technicians should reinsert the original part for another test. First depower the system before completing the tasks of removing the rear door scuff plate and safety belt anchor bolt installation of 40 Nm (30 lb-ft) torque during reassembly. To reach the side impact sensor and access it properly you should first pull out the C-pillar quarter trim panel while separating the weather strip when needed. The procedure begins with dissociating the electrical connector while removing the speaker bolt and speaker nut. The side impact sensor electrical connector needs disconnecting before freeing the sensor with its two securing bolts which should be tightened to 12 Nm (9 lb-ft) at installation. The safety belt webbing should be untwisted before performing the reinstallation steps for the side impact sensor. Execute the final stages by powering up the system while testing the correct functioning of the active restraint system.
