1) Before assembly
- Check that all markings on the original and new part match, especially 9665730180 and 8217G3.
- Compare the shape of the sensor body, connector, number of pins, mounting and orientation of the part.
- Inspect the connector and the sensor itself to see if it is cracked, deformed, oxidized or mechanically damaged.
- Disconnect the battery and wait a reasonable amount of time according to normal service practice before any handling of airbag system components.
2) Necessary tools and materials
- Basic set of hand tools
- Suitable bits and sockets
- Plastic levers for removing covers
- Electrical contact cleaner
- Clean lint-free cloth or cloth
- Protective gloves
3) Step-by-step assembly procedure
- Park the vehicle in a safe place and turn off the ignition.
- Disconnect the battery and leave the vehicle stationary before starting work.
- Access the area where the original sensor is located by removing any necessary covers or trim.
- Disconnect the electrical connector of the original sensor carefully, without force and without damaging the fuse of the connector.
- Unmount the old part and remove it from the holder or mounting position.
- Compare the old and new sensor side by side, including markings, connector and mounting.
- Check the condition of the cabling and the connector, or gently clean the contact surfaces with a suitable product.
- Place the used sensor in the correct position and ensure the same rotation as for the original piece.
