?1.	Turn the vehicle to the OFF (LOCK) mode.

?2.	Disconnect the negative cable from the 12 volt battery, then wait at least 3 minutes.

?3.

Disconnect the following connector.

SRS unit connector A (39P)

?4.	Disconnect the SRS inflator simulator from SRS simulator lead J. Do not disconnect SRS simulator lead J from the front passenger's airbag inflator 4P connector on the dashboard wire harness.

?5.	Connect the SRS short cancellers to SRS unit connector A (39P) terminals No. 4 and No. 5, and terminals No. 6 and No. 7.

?6.

Measure the resistance of the test points.

Test condition	Vehicle OFF (LOCK) mode
	Front passenger's airbag inflator 4P connector (on the dashboard wire harness): disconnected
	SRS unit connector A (39P): disconnected
	Front passenger's airbag inflator 4P connector (on the dashboard wire harness): connected to SRS simulator lead J
	SRS unit connector A (39P) No. 4 and No. 5: connected to SRS short canceller
	SRS unit connector A (39P) No. 6 and No. 7: connected to SRS short canceller
Test point	SRS simulator lead J black terminal

Test point

SRS simulator lead J red terminal

Is there an open circuit, or at least 1 M??


	YES

The RA1?, RA1?, RA2?, and RA2? wires are OK. Faulty SRS unit or poor connection at SRS unit connector A (39P) and the SRS unit. Check the connection; if the connection is OK, check for any authorized service information related to the DTCs or symptoms you are troubleshooting or replace the SRS unit. If the DTC does not clear, replace the dashboard wire harness.?
