1.

PREPARATION
Refer to the DESCRIPTION in this TROUBLESHOOTING section. (See page RT - 36)

2.

CHECK SAB 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 SAB 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 20(7) and 19(8) of SRSCM harness connector(B).

CHECK OPEN CIRCUIT

1)

Measure resistance between the terminal 1 of SAB harness connector and the terminal 20(7) of SRSCM harness
connector(B).

2)

Measure resistance between the terminal 2 of SAB harness connector and the terminal 19(8) of SRSCM harness
connector(B).
