4 Check P/T squib (RH).
PREPARATION:
(a) Turn 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 ACC or ON, and wait at least
for 20 seconds.
(b) Clear the DTC stored in memory
(See step 5 on page DI-349).
(c) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(e) Check the DTC (See page DI-349).
OK:
DTC B0133/62 is not output.
HINT:
Codes other than code B0133/62 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.
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 B0135/73 Short in P/T Squib (LH) Circuit
CIRCUIT DESCRIPTION
The P/T squib (LH) circuit consists of the airbag sensor assembly and seat belt pretensioner (LH).
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 B0135/73 is recorded when a short is detected in the P/T squib (LH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-475).
2 Check P/T squib (LH) 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 (LH)
(See page DI-349).
CHECK:
For the connector (on the seat belt pretensioner side) between
the seat belt pretensioner (LH) and the airbag sensor assembly,
measure the resistance between PL+ and PL-.
OK:
Resistance: 1 MW or Higher
NG Repair or replace harness or connector be-
tween seat belt pretensioner (LH) and airbag
sensor assembly.
OK
