2.
CHECK PAB 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 PAB 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 11 and 12 of SRSCM harness connector(A).
Specification (resistance) : 1.4 ~ 6.2 Ω

3)
Is the measured resistance within specification?
YES
▶ Replace the Passenger Airbag(PAB) module.
NO
▶ Check open circuit.
3.
CHECK OPEN CIRCUIT
1)
Measure resistance between the terminal 1 of PAB harness connector and the terminal 11 of SRSCM harness
connector(A).
2)
Measure resistance between the terminal 2 of PAB harness connector and the terminal 12 of SRSCM harness
connector(A).
Specification (resistance) : below 1 Ω
