DTC B0115/47 SHORT IN SIDE SQUIB (LH) CIRCUIT
CIRCUIT DESCRIPTION
The side squib LH circuit consists of the airbag sensor assy center and the separate type front seat back
assy (side squib LH).
This circuit actuates the SRS to deploy when the SRS deployment conditions are fulfilled.
DTC B0115/47 is recorded when a short circuit is detected in the side squib LH circuit.

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

2 CHECK AIR BAG SENSOR ASSY CENTER
(a) Connect the connector to the airbag sensor assy center.
(b) Connect the negative (±) terminal cable to the battery, and wait for at least 2 seconds.
(c) Turn the ignition switch to the ON position, and wait for at least 10 seconds.
(d)Clear the stored DTCs in the memory (See page 05±1184).
(e) Turn the ignition switch to the LOCK position.
(f) Turn the ignition switch to the ON position, and wait for at least 10 seconds.
(g)Check the DTCs (See page 05±1184).
