• Replace the air bag module if it has been dropped or sus-
tained an impact.
• Do not allow oil, grease or water to come in contact with the
air bag module.
• For removal/installation of the direct-connect SRS connec- tors, refer to SRC-9, "
Direct-connect SRS Component Con-
nectors".
INSTALLATION
Original Passenger Air Bag Module
Installation is in the reverse order of removal.
• For removal and installation of the direct-connect SRS connectors, refer to SRC-9, "
Direct-connect SRS
Component Connectors".
CAUTION:
• Always work from the side of or under front passenger air bag module.
• After the work is completed, perform self-diagnosi s to check that no malfunction is detected. Refer
to SRC-13, "
SRS Operation Check".
Service Replacement Passenger Air Bag Module
1. Install the front passenger air bag module to the instrument
panel pad assembly.
2. Install the instrument panel assembly. Refer to IP-13, "
Removal and Installation".
3. Connect the front passenger air bag module harness connector to yellow 4-pin service replacement air bag connector and fasten connector to mounting bracket.
CAUTION:
• Always work from the side of or under front passenger air bag module.
• After the work is completed, perform self-diagnosi s to check that no malfunction is detected. Refer
to SRC-13, "
SRS Operation Check".
WIRING HARNESS MODIFICATION
The passenger air bag module originally installed in t he vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use t ab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of t he service replacement passenger air bag module.
NOTE:
The wiring harness modification is to be performed only if the vehicle is equipped with the original passenger
air bag which uses direct-connect harness connectors. If the passenger air bag is to be replaced in a vehicle
that has already had the service replacement passenger air bag installed, the wiring harness modification is
not required.
CAUTION:
• Do not attempt to repair or replace damaged dir ect-connect front passenger air bag module connec-
tors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiri ng harness modified.
• Before servicing SRS, turn the igni tion switch off, disconnect both battery cables and wait at least 3
minutes.

REMOVAL
CAUTION:
• Before servicing the SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3 minutes.
• Do not use old bolts; replace with new bolts.
• Check diagnosis sensor unit bracket to make sure it is free of deformities, dents, cracks or rust. If it
shows any visible signs of damage, replace with new one.
• Replace diagnosis sensor unit if it has been dropped or sustained an impact.
• 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 each air bag module and seat belt pre-tensioner.
4. Remove center console. Refer to IP-20, "
Removal and Installation".
5. Disconnect diagnosis sensor unit harness connectors.
6. Remove bolts from the diagnosis sensor unit.
INSTALLATION
Installation is in the reverse order of removal.
• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to SRC-
13, "SRS Operation Check".
CAUTION:
• After replacing the air bag diagnosis sensor unit, confirm using CO NSULT-III that the ECU discrimi-
nated number (identification number) of the ne w replacement air bag diagnosis sensor unit matches
the ECU discriminated number (identification numb er) of the replaced (old) air bag diagnosis sensor
unit.
