WARNING:
• When servicing the SRS, do not work from directly in front of air bag module.
• Always place air bag module with pad side facing upward.
CAUTION:
• Before servicing the SRS, turn ignition switch OFF, discon-
nect both battery terminals, then wait at least three minutes.

REMOVAL
WARNING:
Before disconnecting diagnosis sensor unit harness connector(s), be sure to disconnect harness con-
nectors from air bag modules and front seat belt pre-tensioner to prevent deployment by static elec-
tricity.
CAUTION:
• Before servicing the SRS, turn th e ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not disassemble diagnosis sensor unit.
• Do not use old bolts; replace with new bolts.
• Replace the diagnosis sensor unit if it has been dropped or sustained an impact.
• Check diagnosis sensor unit bracket to make sure it is free of deformities, dents, cracks or rust. If it
shows any visible signs of da mage, replace with new one.
• The diagnosis sensor unit must always be installed with the arrow mark " ⇐" pointing toward the
front of the vehicle for proper operation.
• When replacing the air bag diagno sis sensor unit, always check with the parts department for he lat-
est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the
air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags
and seat belt pre-tensioner in a collision r esulting in serious personal injury or death.
1. Always check the air bag diagnosis sensor unit E CU discriminated number (identification number) using
CONSULT-III.
2. Disconnect the negative and positive battery term inals, then wait at least three minutes.
3. Disconnect the harness connectors for the following SRS components: Refer to SRS-40, "
Removal and
Installation" (Side curtain air bag module), SRS-44, "Removal and Installation" (Front seat belt pre-ten-
sioner), SE-12, "
Passenger Seat" (Side air bag module).
4. Remove center console assembly. Refer to IP-11, "
Component Parts".
5. Disconnect diagnosis sensor unit connectors.
6. Remove the bolts and the ground bolt, then remove the diagnosis sensor unit.
INSTALLATION
Installation is in the reverse order of removal.
