TORS.
Check for poor contact of the connectors
between the airbag control module and the seat
belt pretensioner RH.
Is there poor contact? Replace the airbag
rear harness RH
along with body
harness. Go to step 2 .
2 CHECK SEAT BELT PRETENSIONER.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB26) from seat
belt pretensioner (RH).
3) Connect the connector (1N) in the test har-
ness N to the connector (AB26).
4) Connect the airbag resistor to the connector
(2N) of test harness N.
5) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off? Replace the seat
