5 Check sub wire harness.
PREPARATION:
Disconnect the sub wire harness connector on the airbag sen-
sor assembly side.
CHECK:
(a) Turn ignition switch to ON.
(b) For the connector (on the sub wire harness side) between
the side airbag assembly and the sub wire harness, mea-
sure the resistance between SFL+ and body ground.
OK:
Voltage: 0 V
NG Repair or replace sub wire harness.
OK
6 Check harness between airbag sensor assembly and sub wire harness.
CHECK:
(a) Turn ignition switch to ON.
(b) For the connector (on the sub wire harness side) between
the airbag sensor assembly and sub wire harness, mea-
sure the voltage between SFL and body ground.
OK:
Voltage: 0 V
NG Repair or replace harness or connector be-
tween airbag sensor assembly and sub wire
harness.
OK
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use the simulation method to check. If the malfunctioning part can not be
detected by the simulation method, replace all SRS components including the wire harness.

DTC B0130/63 Short in P/T Squib (RH) Circuit
CIRCUIT DESCRIPTION
The P/T squib (RH) circuit consists of the airbag sensor assembly and seat belt pretensioner (RH).
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS±2.
DTC B0130/63 is recorded when a short is detected in the P/T squib (RH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI±787)
2 Check P/T squib (RH) circuit.
PREPARATION:
Release the airbag activation prevention mechanism of the
connector (on the airbag sensor assembly side) between the
airbag sensor assembly and the seat belt pretensioner (RH).
(See page DI±626).
CHECK:
For the connector (on the seat belt pretensioner side) between
the seat belt pretensioner (RH) and the airbag sensor assem-
bly, measure the resistance between PR+ and PR±.
OK:
Resistance: 1 MW or Higher
NG Repair or replace harness or connector be-
tween seat belt pretensioner (RH) and airbag
sensor assembly.
