Removal and installation
When removing the multi-function switch on vehicles equipped with an airbag, be careful and comply with the following conditions.
1. Do not disassemble any of the components of the SRS. Disassembly of components may disable the safety system.
2. Avoid contact with solvents or cleaning agents on the airbag.
3. Transport the air bag separately, bag side up.
4. If any SRS component has been dropped or has cracks, dents, or other defects in the housing, bracket, or connector, replace them with new ones.
5. When transporting, do not put your hands on the airbag.
6. Do not heat the airbag unit to temperatures above 93°C.
7. After deploying the airbag, replace the sensor coil spring with a new one.
8. Before installing the airbag sensor coil spring, align the mark and the sensor spring neutral pointer with the front wheels set to drive straight ahead. If the coil spring mark is not aligned properly, the steering wheel will not be able to turn fully or the coil spring wire will be damaged, preventing the SRS from working properly.
Order of execution
1. Remove the driver's airbag.
2. Remove the steering wheel.
3. Turn out screws and remove the top and lower casings of a steering column.
4. Turn out screws and remove the multipurpose switch.
5. Installation is carried out in the reverse order of removal.
