CIRCUIT DESCRIPTION
The side squib RH circuit consists of the airbag sensor assy center and the\
separate type front seat back
assy (side squib RH).
This circuit actuates the SRS to deploy when the SRS deployment conditio\
ns are fulfilled.
DTC B0113/42 is recorded when a short to B+ is detected in the side squib RH ci\
rcuit.

INSPECTION PROCEDURE
1 CHECK FLOOR WIRE NO.2(SIDE SQUIB RH 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 RH).
(d) Connect the negative (±) terminal cable to the battery,
and turn the ignition switch to the ON position.
(e) Measure the voltage between the body ground and SFR+ of the connector ºCº.
OK:
Voltage: Below 1 V
