Removal and InstallationNHS0009H
REMOVAL
CAUTION:

Before servicing, turn ignition switch OFF, disconnect both battery terminal and wait at least 3
minutes.

Do not use air tools or electric tools for servicing.

Do not use old fixing nuts after removal; replace with new nuts.

Do not make an impact to the side air bag (satellite) sensor by dropping etc. Replace the side air
bag (satellite) sensor if it has been dropped or sustained an impact.

Replace the satellite sensor of deployed SRS front side air bag and deployed SRS side curtain air
bag.
1. Remove the side air bag (Satellite) sensor.
