Installation
Follow all safety precautions when working on pyrotechnic components. Refer to => [ Restraint System Components, Safety Precautions and General Information ] Restraint System Components, Safety Precautions and General Information.
Installation is reverse of removal, noting the following:
• Damaged bushings - 1 - cannot be replaced with workshop materials.
• If the bushings are damaged, lower seat pan frame - 2 - must be replaced.
- Clean the threaded bolt holes for self-locking nuts, for example using a thread tap.
- Replace all self-locking bolts.
Before handling airbag units (for example, when disconnecting the harness connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.
- Make sure the clip - A - and plastic toothed segment collar - 2 - as well as locking pins - B arrows - are inserted correctly in holes on fitting - 1 -.
- Make sure the plastic toothed segment - 2 - is clipped to fitting - 1 - correctly.
Plastic toothed segment collar - arrow C - must contact fitting - 1 - evenly.
- Route and secure wiring according to photos or sketches that were made.
- Ensure all connectors are engaged correctly.
• Make sure the connectors are installed all the way in and are secure.
• Make sure the wires do not get caught.
Ignition must be on when connecting battery. If pyrotechnic components (for example, airbag, belt tensioner) are not repaired correctly, they may deploy unintentionally after connecting battery. Maintain personal safety when connecting the battery by staying out of airbag deployment areas, keeping a distance from belt tensioners/seat belts and ensuring no other people are in the vehicle interior at the moment when the battery is connected.
- Switch on ignition.
- Connect the battery ground cable with the ignition turned on.
- If the airbag indicator lamp (K75) indicates a fault after installation, the DTC memory must be checked, deleted and checked again. Refer to Vehicle diagnostic tester.
- In the case of memory seats: perform a basic setting for the backrest or seat after installation of the seat in the vehicle. Refer to Vehicle diagnostic tester.
