the battery ground cable, and wait more than
20 seconds.
2)Remove the glove box.
3)Disconnect the connector (AB10) from
(AB9).
4)Connect the connector (1F) in test harness F
to connector (AB9).
5)Connect the airbag resistor to connector (3F)
in test harness F.
6)Connect the battery ground cable and turn
the ignition switch to ON.
