General Description
AIRBAG SYSTEM
•When checking, use a test harness (1). Damage
to connector terminal cause malfunction. Do not di-
rectly apply the tester probe to connector terminal
of airbag.
•Do not allow water or oil to come in contact with
the connector terminals. Also do not touch the con-
nector terminals.
•Do not check continuity of the airbag modules for
driver’s side, passenger’s side and curtain, or the
pretensioner.
•If damage, open circuit or rust is found on airbag
system wire harness, do not use a soldering equip-
ment to repair. Replace the faulty harness with a
new genuine part.
•Install the wire harness securely with the speci-
fied clips to avoid interference or tangled with other
parts.
•When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender and front side frame, re-
move the front sub sensors and wire harness of air-
bag system.
•When painting or performing sheet metal work
on the side of the vehicle, including the side sill,
center pillar and front and rear doors, remove the
side airbag sensors and wire harness of the airbag
system.
•Do not use the airbag or pretensioner parts from
other vehicles. Always replace the defective parts
with new parts.
•Never reuse a deployed airbag module and pre-
tensioner.

(DTC).>
NOTE:If the communication function of the Subaru Se-
lect Monitor cannot be executed normally,
check the communication circuit. AB(diag)-33, COMMUNICATION FOR INI-
TIALIZING IMPOSSIBLE, INSPECTION, Sub-
aru Select Monitor.>

ing Light Fail-
ure.>Go to “Airbag
Wa r ni n g L ig h t Fa i l-
ure”.
3PERFORM DIAGNOSIS.
