DTC 12-5X ("X" CAN BE 0 THRU 9 OR A THRU F): INCREASED RESISTANCE IN FRONT
PASSENGER'S AIRBAG SECOND INFLATOR

Special Tools Required



SRS inflator simulator 07SAZ-TB4011A



SRS simulator lead F 07XAZ-SZ30100

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 12-1x, 12-2x, 12-4x, or 12-5x 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 the dashboard wire harness A.

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

harness A.

6. Reconnect the negative cable to the battery.

7. Clear the DTC memory.

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and
Procedures (see PRECAUTIONS AND PROCEDURES ) and General
Troubleshooting Information (see GENERAL TROUBLESHOOTING
INFORMATION ).

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

Is DTC 12-1X, 12-2x, 12-4x, or 12-5x indicated?

YES - Go to step 9.

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

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

10. Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 ). Do not disconnect the

simulator lead from the dashboard wire harness A 4P connector.

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

12. Measure the resistance between the terminals of the SRS simulator lead. There should be 1 ohms or

less.

Is the resistance as specified?

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

NO - Open or increased resistance in dashboard wire harness A; replace dashboard wire harness A.

DTC 12-3X ("X" CAN BE 0 THRU 9 OR A THRU F): SHORT TO ANOTHER WIRE OR
DECREASED RESISTANCE IN FRONT PASSENGER'S AIRBAG FIRST INFLATOR; DTC 12-6X
