INSPECTION PROCEDURE
1CHECK FLOOR WIRE(SIDE SQUIB LH CIRCUIT)
(a)Turn the ignition switch to the LOCK position.
(b)Disconnect the negative (±) terminal cable from the bat-
tery, and wait for at least 90 seconds.
(c)Disconnect the connectors from the airbag sensor assy center and the separate type front seat back assy (side
squib LH).
(d)Release the activation prevention mechanism built in the
connector ºBº (See page 05±1184).
(e) Measure the resistance between SFL+ and SFL± of the connector ºCº.
OK:
Resistance: 1 M
or Higher
