2.
CHECK BPT RESISTANCE
CAUTION
Never attempt to measure the circuit resistance of the airbag module(squib) even if you are using the speci-
fied tester.
1)
Connect the Dummy and the Dummy Adapter on BPT harness connector.
● Refer to "SPECIAL SERVICE TOOL" section in this SERVICE MANUAL for the SST No. of Dummy and
Dummy Adapter.
2)
Measure resistance between the terminal 17(10) and 18(9) of SRSCM harness connector(B).
Specification (resistance) : 1.4 ~ 6.2 Ω

3)
Is the measured resistance within specification?
YES
▶ Replace the Seat Belt Pretensioner(BPT) module.
NO
▶Check open circuit.
3.
CHECK OPEN CIRCUIT
1)
Measure resistance between the terminal 1 of BPT harness connector and the terminal 17(10) of SRSCM har-
ness connector(B).
2)
Measure resistance between the terminal 2 of BPT harness connector and the terminal 18(9) of SRSCM harness
connector(B).
