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.
Remove front seat belt. Refer to SB-30, "Removal and Installation of Front Seat Belt" .
Remove fixing nuts, then remove side air bag (Satellite) sen-
sor.
Disconnect the side air bag (Satellite) sensor harness con-
nector.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Be careful not to damage the satellite sensor harness.
After the work is completed, make sure no system malfunction is detected by air bag warning
lamp.
In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis func-
tion and delete the memory by CONSULT
ll.
In case that malfunction is still detected after the above operation, perform self-diagnosis to repair
malfunctions. Refer to SRS-19, "
SRS Operation Check" . Fixing nut

Revision: 2006 January2006 M35/M45
For Side CollisionNHS0009M
WHEN THE SIDE AIR BAG IS ACTIVATED IN THE SIDE COLLISION:
1. Replace the following components:
–All parts of front seatback (including front seatback frame) with front side air bag module (on the side on
which front side air bag is activated)
–Curtain air bag module (on the side on which side curtain air bag is activated)
–Diagnosis sensor unit
–Satellite sensor (on the side on which side air bag and side curtain air bag is activated)
2. Check the SRS components and the related parts using the following table.
–Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
3. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" . Ensure entire SRS operates properly.
WHEN SRS IS NOT ACTIVATED IN THE SIDE COLLISION:
1. Check the SRS components and the related parts using the following table.
–Replace any SRS components and the related parts showing visible signs of damage (dents, cracks,
deformation).
2. Conduct self-diagnosis using CONSULT-II or “AIR BAG” warning lamp. Refer to SRS-19, "
SRS Operation
Check" . Ensure entire SRS operates properly.
