rear harness RH
with body harness.
5CHECK AIRBAG REAR HARNESS RH (PRE-
TENSIONER HARNESS RH).
Measure the resistance between connector
(3U) in the test harness U and chassis ground.
Connector & terminal
(3U) No. 17 — Chassis ground:
(3U) No. 19 — Chassis ground:

illuminate for 6 seconds and go
off?
Replace the seat
belt pretensioner
(LH). 10, Front Seat
Belt.>
Go to step 3.
3CHECK AIRBAG REAR HARNESS LH (PRE-
TENSIONER HARNESS LH).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the airbag resistor from test
harness.
3) Disconnect the connector (AB19) from side
airbag module (LH).
4) Disconnect the connector (AB31) from cur-
tain airbag module (LH).
5) Disconnect the connectors (AB17) and
(AB18) from airbag control module.
6) Connect the connector (1U) in the test har-
ness U to connector (AB17).
7) Measure the resistance between connector
(3U) in the test harness U and connector (2N)
in the test harness N.
Connector & terminal
(3U) No. 13 — (2N) No. 1:
(3U) No. 11 — (2N) No. 2:
