Tesla Model 3: 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:

Warning: Do not use a multimeter or other general purpose test equipment on SRS components. Only use the recommended diagnostic equipment to diagnose SRS system faults.

Warning: Do not use electrical test equipment on any SRS harness unless all SRS components are disconnected.

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.

Warning: Store the airbag module with the deployment side facing up. This will prevent it from being propelled if accidentally deployed, which might cause injury.

Warning: Improper handling or storage can internally damage airbag modules and pretensioners, making them inoperative. If you suspect a module has been damaged, install a new component and refer to the Deployment/Disposal Procedures for disposal of the damaged module.

SRS Harnesses and Connectors

Note: SRS wiring can be identified by a special yellow outer sleeve protecting the wires (black with yellow stripe protective coverings are sometimes used).

Warning: Never attempt to modify, splice, or repair SRS wiring.

Warning: Never install electronic equipment (such as a mobile telephone, two-way radio, or in-car entertainment system) in such a way that it could generate electrical interference in the SRS harnesses. Seek specialist advice when installing such equipment.

Warning: Always make sure that SRS wiring is routed correctly. Be careful to avoid trapping or pinching the cables. Do not leave the connectors hanging loose, or allow SRS components to hang from their harnesses. Look for possible points of chafing.

Warning Labels

Warning: Read and follow all warnings and cautions printed on SRS component warning labels.


     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: Warning: Only
