Airbag/Supplementary Restraint System (SRS) Repairs And Inspections Required After A Collision
WARNING:
Explosive materials
Failure to follow specified procedures may result in death or serious injury due to improper handling of airbags possible.
Failure to follow specified procedures may result in death or serious injury due to improper handling of airbags possible.
- Only appropriately trained persons may carry out work on pyrotechnic components or the Airbag Control Unit.
- Perform SRS disabling procedure prior to commencing work.
- When replacing components of the SRS system, never install used or non-genuine components.
- Pyrotechnic Components must be handled and scrapped appropriately.
- Any repairs to the vehicle structure must be returned to the original production configuration.
- Do not repair the seat stitching or seams in the seat trim cover with an internal mounted seat side airbag module.
- Replace the complete seat trim cover & foam using original VinFast part.
Ensure the 2-minute wait time has been observed before proceeding to next step.
- After ANY
collision, perform the following seat belt checks:
- Turn the ignition switch to the ON position. Verify proper operation of the seat belt reminder lamp with the belt buckled and with the belt unbuckled.
- For each seating position:
- Inspect the shoulder belt guide (1) to ensure the seat belt webbing (2) is seated flat in the guide slot and that the seat belt webbing does not bind.
- Verify that the seat belt buckle (3) is accessible.
- Fully extend the seat belt webbing and verify that the seat belt webbing does not have twists, tears or any other defects.
- Release the seat belt and allow the webbing to retract. Verify that the seat belt webbing returns freely and completely back into the retractor.
- Snap the seat belt latch (4) into the buckle. Sharply tug on the seat belt latch and buckle. Verify that the seat belt latch and buckle remain locked when tugged.
- Push the button on the buckle. Verify the seat belt latch releases easily from the buckle and the button returns back to its original position.
- In instances of vehicle collision where damage is limited to minor outer body panel cosmetic distortion, visually inspect vehicle for extent of damage, repair and replace components as necessary.
- In instances of vehicle collision where damage exceeds minor outer body panel cosmetic distortion, unrelated components can be subject to damage outside of obvious visual detection method in the area of impact.
The table below references components requiring inspection or replacement to promote a safe and quality repair.
Some inspections may require disassembly of vehicle components or additional functional tests. If you detect any damage, replace the component.

The impact sensors must be replaced in the area of the accident damage. The area of accident damage is defined as the portion of the vehicle which is crushed, bent, or damaged due to a collision. If the impact sensor or the mounting structure of the impact sensor is damaged, the impact sensor must be replaced.
Replace the impact sensor whether or not the air bags have deployed.
Replace the impact sensor even if it appears to be undamaged.
Impact sensor damage which is not visible, such as slight bending of the mounting bracket or cuts in the wire insulation, can cause improper operation of the SRS system. Do not try to determine whether the impact sensor is undamaged, replace the impact sensor. Also, if you follow a diagnostic trouble code (DTC) procedure and a malfunctioning impact sensor is indicated, replace the impact sensor.Replace Replace Replace Impact Sensors Mounting Points and Hardware - Inspect Inspect Inspect Instrument Panel Instrument Panel Cross Car Beam - Inspect Inspect Inspect Instrument Panel Knee Bolsters and Mounting Points - Inspect Inspect Inspect Instrument Panel Mounting Points and Instrument Panel Brackets, Braces, etc. - Inspect Inspect Inspect Instrument Panel Air Bag Mounting Points and Hardware - Inspect Inspect Inspect Instrument Panel Airbag Visually inspection the top trim cover of the airbag module for deformation, distortion, or indentations as a result of damage.

Do NOT replace single seat belt system components in vehicles that have been in a collision as described above. Always replace the entire seat belt system with the buckle, guide, and retractor assembly, which includes the latch and webbing material.
Closely inspect any seat belt system that was in use during the collision serious enough to deploy any airbag.
Replace any seat belt system that has torn, worn, or damaged components.
Replace any seat belt system if you are doubtful about its condition.Inspect - - Seat Belt Anchor and/or Retractor - Inspect Replace Replace Seat Belt Anchor and/or Retractor Pretensioners Mounting Points and Hardware Visually verify the seat belt retractor units are securely attached and the seat belt anchor bolts are secure.
