11. Disconnect the SRS inflator simulator from the SRS simulator lead.

12. Connect a SRS short canceller (070AZ-SAA0100) to No. 9 and No. 10 terminals and the No. 3 and

No. 4 terminals of SRS unit connector A (28P) (see OPENING THE SRS UNIT SHORTING
CONNECTORS FOR DIAGNOSIS ).

13. Measure the resistance between the terminals of the SRS simulator lead. There should be an open

Is the resistance as specified?

YES - Faulty SRS unit or poor connection at SRS unit connection A (28P) and the SRS unit. Check
the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit
(see SRS UNIT REPLACEMENT ).

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and

then goes off.

Does the SRS indicator stay on, and is DTC 12-8x or 12-Ax indicated?

YES - Go to step 3.

NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING
INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.

3. Turn the ignition switch OFF. Disconnect the negative cable from the battery, then wait for 3 minutes.

4. Disconnect the front passenger's airbag 4P connector (A) from dashboard wire harness A.

5. Connect the SRS inflator simulator (2 ohms connectors) and simulator lead F to the dashboard wire

harness A.

6. Reconnect the negative cable to the battery.

7. Clear the DTC memory.

8. Read the DTC (see GENERAL TROUBLESHOOTING INFORMATION ).

Is DTC 12-8x or 12-Ax indicated?

YES - Go to step 9.

NO - Short to power in the front passenger's airbag first or second inflator; replace the front
passenger's airbag (see FRONT PASSENGER'S AIRBAG REPLACEMENT ).
