Is the resistance as specified?

YES - Open or increased resistance in the left side wire harness; replace left side wire harness.

NO - Open or increased resistance in the right side wire harness; replace the right side wire harness.

DTC 31-3X ("X" CAN BE 0 THRU 9 OR A THRU F): SHORT TO ANOTHER WIRE OR
DECREASED RESISTANCE IN DRIVER'S SIDE AIRBAG INFLATOR

Special Tools Required



SRS inflator simulator 07SAZ-TB4011A



SRS simulator lead E 07XAZ-S1A0200



SRS short canceller 070AZ-SAA0100

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 31-3x 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 left side wire harness 2P connector (A) from the driver's side airbag (B).

5. Connect the SRS inflator simulator (2 ohms connectors) and simulator lead E to the left side wire

harness.

6. Reconnect the negative cable to the battery.

7. Clear the DTC memory.

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

Is DTC 31-3x indicated?

YES - Go to step 9.

NO - Short to another wire in the driver's side airbag inflator; replace the driver's side airbag (see
SIDE 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 C (28P) from the SRS unit (see step 7 ).

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

12. Connect the SRS short canceller (070AZ-SAA0100) to the No. 1 and No. 2 terminals of SRS unit

connector C (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

circuit or at least 1M ohms.

Is the resistance as specified?

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

NO - Go to step 14.

14. Disconnect right side wire harness 16P connector C604 (A) from the left side wire harness connector

15. Measure the resistance between the No. 13 [No. 1] terminal of the right side wire harness 16P

connector C604 and body ground, and between the No. 14 [No. 7] terminal and body ground. There
should be an open circuit or at least 1Mohms.
