3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Using a service wire, connect PR+ and PR± of the con-
nector (on the seat belt pretensioner side) between the
seat belt pretensioner (RH) and the airbag sensor assem-
bly.
(c) Connect negative (±) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn ignition switch to ACC or ON and wait at least for 20
seconds.
(b) Clear DTC stored in memory (See page DI±223).
(c) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(e) Check DTC (See page DI±223).
OK:
DTC B0131/64 is not output.

DTC B0132/61 Short in P/T Squib (RH) Circuit
(to Ground)
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 Pub. No. RM654U on page RS±2.
DTC B0132/61 is recorded when a ground short is detected in the P/T squib (RH) circuit.
