• When servicing the SRS, do not work from directly in front of air bag module.
• Always place the curtain air bag module with deployment side facing upward.
• Do not reuse center pillar upper garnish if removed.
CAUTION:
• Before servicing SRS, turn the ig nition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not use old bolts after removal; replace with new bolts.
• Do not insert any foreign objects (screwdriver, etc.) into air bag module or harness connectors.
• Do not disassemble air bag module.
• Do not expose the side curtain air bag module to temperatures exceeding 90 °C (194 °F).
• Replace the side curtain air bag module if it has been dropped or sustained an impact.
• Do not allow oil, grease or water to come in contact with the
side curtain air bag module.
• Do not attempt to repair or replace damaged direct-connect SRS component connectors. If a direct-connect harness con-
nector is damaged, the harness must be replaced.
1. Disconnect both the negative and positive battery te rminals, then wait at least three minutes.
2. Remove the headlining. Refer to EI-48
.
3. Disconnect side curtain air bag module connector. NOTE:
For removal/installation of the direct-connect SRS connectors,
refer to SRS-7, "
Direct-connect SRS Component Connectors".
4. Remove the bolts in order starting at the rear, then remove the side curtain air bag module.
INSTALLATION
Installation is in the reverse order of removal.
• For removal/installation of the direct-connect SRS connectors, refer to SRS-7, "
Direct-connect SRS Compo-
nent Connectors".
• After replacement of side curtain air bag module, per form self-diagnosis to check that no malfunction is
detected. Refer to SRS-19, "
SRS Operation Check".
