4 Check P/T squib (RH).
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect negative (-) terminal cable from the battery,
and wait at least for 90 seconds.
(c) Connect the seat belt pretensioner (RH) connector.
(d) Connect negative (-) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to LOOK, and wait at least for 20
second.
(b) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(c) Clear the DTC stored in memory (See page DI-349).
(d) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(e) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(f) Check the DTC (See page DI-349).
OK:
DTC B0130/63 is not output.
HINT:
Codes other than code B0130/63 may be output at this time, but
they are not relevant to this check.
NG Replace seat belt pretensioner (RH).
OK
From the results of the above inspection, the malfunctioning part can now be considered normal.

DTC B0131/64 Open in P/T Squib (RH) Circuit
CIRCUIT DESCRIPTION
The P/T squib circuit (RH) 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-3.
DTC B0131/64 is recorded when an open is detected in the P/T squib (RH) circuit.
