4 Check P/T squib RH.
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect the negative (-) terminal cable from the bat-
tery, and wait at least for 90 seconds.
(c) Connect the seat belt pretensioner RH (P/T squib RH)
connector.
(d) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(b) Clear the DTC stored in memory (See page DI-692).
(c) Turn the ignition switch to LOCK, and wait at least for 10
seconds.
(d) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
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

DTC B0131/64 Open in P/T Squib RH Circuit
CIRCUIT DESCRIPTION
The P/T squib RH circuit consists of the airbag sensor assembly and the 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.
