Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead J 070AZ-SNAA100
- Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components, of the correct part number, and that they were properly installed. (See COMPONENT REPLACEMENT/INSPECTION AFTER DEPLOYMENT ).
- Before doing this troubleshooting procedure, review SRS PRECAUTIONS AND PROCEDURES , General Troubleshooting Information (see DTC (DIAGNOSTIC TROUBLE CODES) ), and BATTERY TERMINAL DISCONNECTION AND RECONNECTION .
- Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software (see SRS UNIT UPDATE ), and retest.
- Clear the DTCs with the HDS (see CLEAR THE DTC MEMORY ).
- Turn the ignition switch to ON (II), then wait for 10 seconds.
- Check for the DTCs with the HDS (see READING THE DTC
).
Is DTC 11-9x or 11-Bx indicated?
YES - Go to step 4.
NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.
- Turn the ignition switch to LOCK (0).
- Disconnect the negative cable from the battery, then wait at least 3 minutes.
- Remove the access panel from the steering wheel (see Driver's Airbag Replacement ).
- Disconnect the driver's airbag 4P connector (A) from the cable reel.
- Connect the terminals of SRS simulator lead J to the SRS inflator simulator (2 Ω connectors), and then connect SRS simulator lead J to the driver's airbag inflator 4P connector on the cable reel harness.
- Reconnect the negative cable to the battery.
- Clear the DTCs with the HDS (see CLEAR THE DTC MEMORY ).
- Turn the ignition switch to ON (II), then wait for 10 seconds.
- Read the DTC (see READING THE DTC
).
Is DTC 11-9x or 11-Bx indicated?
YES - Go to step 13.
NO - Short to ground in the driver's airbag first or second inflator; replace the driver's airbag (see DRIVER'S AIRBAG REPLACEMENT ), then clear the DTC.
- Turn the ignition switch to LOCK (0).
- Disconnect the negative cable from the battery, then wait at least 3 minutes.
- Remove the column cover (see COLUMN COVER REMOVAL/INSTALLATION ), then disconnect the dashboard wire harness 4P connector (A) from the cable reel.
- Connect the terminals of SRS simulator lead J to the SRS inflator simulator (2 Ω connectors), and then connect SRS simulator lead J to the cable reel 4P connector on the dashboard wire harness.
- Reconnect the negative cable to the battery.
- Clear the DTCs with the HDS (see CLEAR THE DTC MEMORY ).
- Turn the ignition switch to ON (II), then wait for 10 seconds.
- Check for the DTCs with the HDS (see READING THE DTC
).
Is DTC 11-9x or 11-Bx indicated?
YES - Go to step 21.
NO - Short to ground in the cable reel; replace the cable reel (see CABLE REEL REPLACEMENT ), then clear the DTC.
- Turn the ignition switch to LOCK (0).
- Disconnect the negative cable from the battery, then wait at least 3 minutes.
- Disconnect SRS unit connector A (39P) from the SRS unit (see step 10 under Disconnecting System Connectors ).
- Disconnect the SRS inflator simulator from both SRS simulator leads. Do not disconnect the simulator lead from the dashboard wire harness 4P connector.
- Measure the resistance between each terminal of SRS simulator lead J and body ground individually.

Is there an open circuit, or at least 1 MΩ ?
YES - Faulty SRS unit or poor connection at SRS unit connector A (39P) 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 ). If the DTC does not clear, replace the dashboard wire harness.
NO - Short to ground in the dashboard wire harness; replace the dashboard wire harness, then clear the DTC.
