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 the service replacement passenger air bag module. Refer to
"WIRING HARNESS MODIFICATION" for wiring harness modification procedure.

CAUTION:
• Do not attempt to repair or replace damaged direct-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 wiring harness modified.

WIRING HARNESS MODIFICATION
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-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 the 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 direct-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 wiring harness modified.
• Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least 3
minutes.
• Always work from the side of or under front passenger air bag module.
• After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer
to SRS-20, "
SRS Operation Check" .
