| Safety measures when working with pyrotechnic components |
Note | The following are pyrotechnic components: |
| t
| Belt force limiters (depending on vehicle equipment level) |
| t
| Battery isolation elements (depending on vehicle equipment level) |
| t
| Only trained personnel may carry out test, assembly and repair work. |
| t
| There are no replacement intervals for airbag units. |
| t
| Under no circumstances should checks be carried out with a test lamp, voltmeter or ohmmeter. |
| t
| Pyrotechnic components may only be checked in installed state and with vehicle diagnosis, testing and information systems approved by the manufacturer. |
| t
| When working on pyrotechnic components and airbag control unit -J234-, battery earth strap must be disconnected with ignition switched ON. Then cover negative terminal. |
| t
| A waiting time of 10 seconds is necessary after disconnecting the battery. |
| t
| The battery must be connected with the ignition switched ON. When doing this, there should be no-one inside the vehicle. Exception: Vehicles with battery inside passenger compartment. In this case do not stay anywhere near the effective range of the airbags and seat belts. |
| t
| Before handling pyrotechnic components of the restraint system, for example before isolating an electrical connection, the mechanic must electrostatically discharge himself/herself. Electrostatic discharge is achieved by touching earthed metallic parts, such as the door striker plate. |
| t
| Wash hands after coming into contact with triggered pyrotechnic components of restraint system. |
| t
| Pyrotechnic components must not be opened or repaired; always use new parts (risk of injury). |
| t
| Pyrotechnic components that have been dropped onto a hard surface or show signs of damage must not be installed in a vehicle. |
| t
| Pyrotechnic components must be installed immediately after they have been removed from their packaging. |
| t
| If work is interrupted, the pyrotechnic component must be stored back in its packaging. |
| t
| Leaving the pyrotechnic component unattended is prohibited. |
| t
| When connecting restraint system pyrotechnic components, only the person carrying out the work may be inside the vehicle. |
| t
| Pyrotechnic components must not come into contact with grease, cleaning solution or similar. |
| t
| The airbag unit must be replaced if any contamination such as oil, paint or solvent penetrates the fabric. |
| t
| Pyrotechnic components must not be subjected to temperatures above 100°C even for short periods. |
