DTC B0132/62 Short in P/T Squib (RH) Circuit (to B+)
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-3.
DTC B0133/62 is recorded when a B+ short is detected in the P/T squib (RH) circuit.

See page DI-418.
INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-475).
2 Check P/T squib (RH) circuit.
CHECK:
(a) Turn the ignition switch to ON.
(b) For the connector (on the seat belt pretensioner side) be-
tween the seat belt pretensioner (RH) and the airbag sen-
sor assembly, measure the voltage between PR+ and
body ground.
OK:
Voltage: 0 V
NG Repair or replace harness or connector be-
tween seat belt pretensioner (RH) and airbag
sensor assembly.
OK
