Handling Deployed Pyrotechnical Part
METHOD CONTENT
This method is divided into three sections:
- Components that must always be replaced
- Components that must be checked and replaced if necessary
- Additional information.
The different sections can be found in separate columns in the table below.
| Components that must always be replaced |
Components that must be checked and replaced if necessary |
Additional information. |
After activation of the driver's side and passenger side airbags (SRS) and/or seat belt tensioners:
- Replace all deployed airbags.
- Replace all deployed seat belt tensioners, including end mountings/quickfix.
- Replace the seat belt buckles corresponding to activated seat belt tensioners.
- Replace the deployed pyrotechnic steering column with a new one.
|
Where there is visible damage (deformation, cracks or material that has melted in the heat):
- The steering wheel.
- The contact reel on the driver's airbag.
- The dashboard if the passenger airbag has deployed.
- The windshield and its adhesive.
- All damaged wiring.
- The Supplemental Restraint System Module (SRS), see section "Additional information".
- The WHIPS mechanism.
- The loudspeakers in the dashboard.
- The panels under the dashboard.
- Steering column
- Remove any broken glass from the windshield from the ventilation ducts.
|
Important:
- When one or more airbags has deployed, the seat belt tensioners in the rear seat (and in the third row rear seat) are automatically activated. For this reason, these seat belt tensioners, the seat belt buckles and the end mountings must be replaced.
- When one or more airbags have deployed, check the seat belt tensioners in the front seats. See SEAT BELT TENSIONER, CHECKING
. The activation of the tensioner function depends on whether the seat belt was in use or not when the airbag deployed.
- Supplemental Restraint System Module (SRS) must always be replaced:
- diagnostic trouble codes (DTCs) cannot be erased
- the control module has suffered mechanical damage
- there is damage to the car floor in the area around the control module. The damage can weaken the mechanical mountings for the control module.
- If the vehicle is equipped with Volvo On Call, both the collision cable and the auxiliary battery must be checked.
- Diagnostic trouble code (DTC) SRS-112 must not be erased during the warranty period. The sensor module should be returned to Volvo in accordance with current procedures.
- It should also be possible to drive the car so that the function of the steering is guaranteed.
|
After activation of inflatable curtain (DMIC):
- replace all deployed inflatable curtains
- Replace all damaged components by the inflatable curtain, e. g.:
- the door panels.
|
After activation of inflatable curtain (DMIC):
- the collision sensors at the B-pillars and the pressure sensors in the doors
- all damaged mounting elements for the inflatable curtain and the panels
- all damaged cable harnesses
- check any components damaged by the inflatable curtain, e. g.: - A-panels
- side panels backseat
- the headlining.
|
After activation of inflatable curtain (DMIC):
- Following a heavy frontal collision, it is possible that the front part of the A-post for the inflatable curtain may be damaged. Check this.
|
After a seat airbag (SIPS) has deployed:
- Replace all deployed airbags.
- Replace the upholstery, foam and impact protection on the seats.
|
After a seat airbag (SIPS) has deployed:
- Check that the seat and the backrest frame on the seat are straight. This may be deformed after deployment of the airbag.
- Replace all damaged cable harnesses.
|
- |
After activation of roll-over protection (ROPS):
- replace all deployed roll-over protection
- replace all components damaged by the roll-over protection
- replace all damaged components on the vehicle.
|
After activation of roll-over protection (ROPS):
|
- |
After whiplash system (WHIPS) deployment:
- Replace the WHIPS mechanism.
|
After whiplash system (WHIPS) deployment:
- Check that the seat has no other visible damage.
|
After whiplash system (WHIPS) deployment:
- Note that the WHIPS system is available in two variants.
