Safety regulations for crash sensors (pressure sensors) for front side airbags
Safety regulations for crash sensors (pressure sensors) for front side airbags
The side airbag crash sensors respond to changes in pressure and must therefore be treated with particular caution. Please note and comply with the following:
t  The correct installation position is vitally important: only install in the specified location in the door.
t  Protect the crash sensor against mechanical shocks and impacts: any crash sensors which have been dropped must no longer be used. Remove the crash sensor when carrying out work on the door bodywork.
t  The crash sensor is matched to the volume of air inside the door: deformation of the door, resulting in a reduction in the air space in the door, impairs the function of the crash sensor.
t  Avoid any major soiling of the crash sensor: do not use compressed air in the vicinity of the crash sensor. Protect the crash sensor against filings or bore chips (example, during retrofitting of door speakers). Do not use cavity sealants or spray oil in the vicinity of the crash sensor.
t  Protect against heat/cold: avoid heat effects, for example during spray painting or other bodyshop operations. The crash sensors must not be exposed to temperatures below -40°C (for example in non-air-conditioned aircraft holds).
t  The crash sensor must be protected against humidity during storage and installation.
For the crash sensor to function properly, it is vital to ensure that the door forms an effective seal after being fitted. Please note and comply with the following:
t  All components (e.g. cover, speakers, door trim) must be correctly fitted.
t  The door trim retaining clips seal the system. If necessary, renew the retaining clips.
