After any collision:

• Inspect the harnesses and harness connectors that connect to all deployed airbags, pretensioners, and to all damaged components. Replace any damaged harnesses.
• Inspect all seats and seat belts for visible deformation or signs of wear on the webbing. Replace any damaged components.
• Inspect the seat belt height adjuster and webbing in the 1st row (behind the B-pillar trim) for signs of wear or deformation. Replace any damaged components.
• Inspect all seats, seat belts, and retractors with pretensioners for visible signs of deformation or signs of wear. Replace any damaged components.
  Note

  When inspecting the seat belt system, pay special attention to the area around the D-ring, where the seat belt webbing passes through the seat shoulder.
• Inspect all seat belt anchor points for damage. Check for tears, bends, dents, fastener damage, or mount point damage. Assess fixing this damage before replacing any sort of seat belt component.
• Inspect the 2nd row seat posts for full range of movement (forward and rearward, seat pitch and tracking motion). If any of the following conditions occur while inspecting, replace the seat post and seat assemblies:
  • Failure to travel the expected range
  • Unusual “metal on metal” noise during movement
  • Actuator strain
• For all the seats that were occupied during a collision: Inspect the following components for cracks:
  • Seat pivot (remove the seat’s lower trim to inspect)
  • Angle bracket where the seat belt buckle assembly mounts to the seat assembly, as shown below (remove the seat’s back trim and seat podium cover to expose the bracket)

    
    
    

• Inspect any impact sensor(s) near the collision area for damage. If the sensor is damaged, replace the sensor, and the hardware that secures it to the vehicle. Refer to the Service Manual for more information about impact sensor replacement.
  Warning

  Always replace any plugs or tape removed from the front door shells when replacing a front door pressure sensor. Additional holes in the door create more escape paths for air, which decreases the sensor's ability to detect a side impact, and can negatively affect airbag deployment.
• Inspect any undeployed knee airbag:
  • If the knee airbag cover is damaged, or if there are 3 or more consecutive broken bridges (as shown below) or 5 or more broken bridges total, replace the complete knee airbag assembly.

    
    
    

  • If there are visible signs of damage to the knee air bag cushion (such as scuffs, rips or holes) replace it.
  • Inspect the knee airbag module for visual damage (such as bent hooks or scuffing), and replace it if damaged.
• Adjust the steering column so that the column shaft (shown in yellow below) is fully retracted inside of the housing. Measure the C-channels (shown in red) on the side of the steering column. If the left C-channel is recessed more than 2.1 mm into the housing, or the right C-channel protrudes less than 19.5 mm from the housing, replace the steering column.

  
  
  

• Inspect Pedestrian Protection components on the vehicle if it is equipped with Pedestrian Protection (see Pedestrian Protection Components for more information), and replace any damaged components.
• Use Toolbox to test the supplementary restraint system for proper operation.
  1. Connect a laptop to the diagnostic port of the vehicle, and then use Toolbox 3 to locally connect to the vehicle. See .
  2. Unlock the vehicle gateway for diagnostic communication. See .
  3. In Toolbox 3, click Dashboards > Service Tools > DTCs, and then select SDM or RCM depending on the vehicle Restraint Control Type.
  4. Click Read DTCs to display the DTCs.
  5. Power cycle the vehicle.
  6. Click Clear DTCs to clear the DTCs.
  7. Determine the RCM type of the vehicle under cfg_restraint_controls. See . If the config shows "DelphiSDM", revert to Toolbox 2 to test the restraint system. If the config shows "BoschRCM", perform the next steps:
  8. Turn on the drive rails.
  9. In Toolbox 3, click the Actiions tab, type "RCM" into the search field, select PROC_RCM_X_SERVICE-TASKS, click Run, and allow the routine to complete.
  10. Cycle the drive rails.

Model X vehicles are equipped with Pedestrian Protection components such as a pressure sensing tube, and hood actuators.

To determine if a vehicle is equipped with Pedestrian Protection components, open the hood and look for Pedestrian Protection hood actuators, as shown above.

If the vehicle is equipped with Pedestrian Protection components, after a frontal collision:

• Replace the Pedestrian Protection hood actuators if they deployed.
• Inspect the Pedestrian Protection pressure sensor tube and connector for signs of damage, such as tears in the tube and cracks in the connector. Replace the pressure sensor assembly if any part has been damaged.

Current airbag component part information can be obtained through the VIN decode feature of the Parts Manual.
