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

Special Tools Required



SRS inflator simulator 07SAZ-TB4011A



SRS simulator lead E 07XAZ-S1A0200

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 31-9x 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).

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and
Procedures (see PRECAUTIONS AND PROCEDURES ) and General

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. Measure the resistance between each terminal of the SRS simulator lead and body ground. There

should be an open circuit or at least 1 Mohms.
