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 terminals 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
1.
Locate the yellow and orange direct-connect passenger air bag module harness connectors.
2.
Use wire cutters to cut back both previously used direct-connect passenger air bag module harness con-
nectors from the vehicle wiring harness approximately 50 mm (1.9 in) from the connectors.
3.
Remove approximately 150 mm (5.9 in) of the vehicle harness covering from the cut end.
4.
Slide a piece of dual-wall heat shrink tubing (provided in the pas-
senger air bag service kit) onto each wire of the previously used
vehicle wiring harness.
5.
Fold each wire back and insert into the end of the heat shrink
tubing so that the end of the wire is approximately centered in
the heat shrink tubing.
6.
Use a heat gun to shrink the heat shrink tubing and seal the wire.
7.
Use electrical tape to secure the modified circuits to the outside of the wiring harness.
8.
Locate the front passenger air bag service replacement connec-
tor that is taped back to the main harness. Unwrap the tape to
access the yellow service replacement connector and remove
the dust cover from the connector.
