Précautions concernant les coussins gonflables et le système de retenue supplémentaire (SRS)
General Precautions
The Supplementary Restraint System (SRS) includes airbags, pretensioners, and other safety-related components. The SRS contains components which could be potentially hazardous to the technician if not serviced and handled correctly.
These precautions are not restricted to operations performed when servicing the SRS; the same care must be exercised when working on other systems and components located near the SRS components:
- Steering system: Driver airbag and knee airbag.
- Dash: Passenger airbag and knee airbag.
- Interior trim: Restraint Control Module (RCM), LH and RH Body Control Modules (BCM), seatbelt pretensioners, and curtain air bags.
- Electrical system: Pyrotechnic fuse, SRS harnesses, link leads, and connectors.
Making the SRS System Safe
Before working on, or in the vicinity of, SRS components, perform the following procedures to disable the SRS system:
-
Use Toolbox to check for any stored fault Diagnostic Trouble Codes (DTCs).
-
Perform the vehicle HV disablement procedure. Refer to procedure 17010000, "Vehicle HV Disablement Procedure."
-
Wait 1 minute for the energy reserve capacitors to discharge.
Installation
Carefully inspect SRS components before installation. Do not install an SRS component if it shows evidence of being dropped or improperly handled, such as dents, cracks, or deformation.
-
Never install used SRS components from another vehicle, or attempt to repair an SRS component. Use only new, genuine Tesla replacement parts.
-
Never use SRS components that lack clear identification labels.
-
Never use a RCM that has been dropped.
-
Never apply electrical power to an SRS component unless instructed to do so as part of an approved test procedure.
-
Always use new fasteners when replacing SRS components. Make sure that the fasteners are tightened to the specified torque.
-
Make sure that SRS components are not contaminated with oil, grease, detergent, or water.
-
Make sure that the RCM is installed correctly. There must not be any gap between the RCM and the body. An incorrectly mounted RCM might cause the SRS system to malfunction.
-
Do not supply power to the RCM until all other SRS components are connected.
SRS Component Testing Precautions
The airbags and other SRS components are triggered using relatively low operating currents. To prevent accidental deployment, always adhere to the following precautions:
Handling and Storage
-
The RCM, pretensioners, and airbags must be stored in a secure steel cabinet at room temperature. The storage area must comply with all legal requirements. It must be away from flammable items and have suitable fire extinguishers or other fire extinguishing equipment. Makes sure that heat, fire, water, and corrosive substances cannot contaminate the stored components.
-
Keep new SRS components in the original packaging until they are ready to be installed.
-
Never wrap your arms around an airbag module. If an airbag module has to be carried, hold it by the cover, with the cover face up and the base away from your body.
-
When handling seatbelt pretensioners with retracting spool assemblies, never point the end of the piston tube towards your body or at other people. Hold with the piston pointing towards the ground. Do not grip by the retractor reel or seatbelt. Hold the outer casing only.
-
Always keep components cool, dry, and free from contamination.
-
Never transport airbag modules or seatbelt pretensioners in the cabin of a vehicle.
-
Never attach anything to an airbag cover or any trim component covering an airbag module. Do not allow anything to rest on top of an airbag module.
-
Do not apply grease or cleaning solvents to seatbelt pretensioner units. Component failure could result.
-
Never drop an airbag or SRS component. The RCM is a particularly shock sensitive device and must be handled with extreme care.

SRS Component Deployment
If a vehicle is to be scrapped and contains an undeployed airbag module or pretensioner, the module or pretensioner must be manually deployed.
Always observe the following precautions:
- Impact: due to inflating airbag or pretensioner operation causing component "kick."
- Hearing: due to noise produced by deploying airbags and seatbelt pretensioner units.
- Burns: hot component parts and gases.
- Irritation to eyes and lungs: from deploying gases or combustion residue.
-
Only use deployment equipment approved for the intended purpose.
-
Test the deployment tool before beginning the deployment procedure.
-
Notify the relevant authorities of intention to deploy SRS components.
