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 11-1x, 11-2x, 11-4x, or 11-5x 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 driver's airbag 4P connector (A) from the cable reel.

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

6. Reconnect the negative cable to the battery.

7. Clear the DTC memory.

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

Is DTC 11-1x, 11-2x, 11-4x, or 11-5x indicated?

YES - Go to step 9.

NO - Open in the driver's airbag first or second inflator; replace the driver's airbag (see DRIVER'S
