DTC 33-8X ("X" CAN BE 0 THRU 9 OR A THRU F): SHORT TO POWER IN LEFT SIDE 
CURTAIN 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 33-8x 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 left side curtain airbag (B). 

NOTE:

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

5. Connect the SRS inflator simulator (2 ohms connector) 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 33-8x indicated?  

YES - Go to step 9. 

NO - Short to power in the left side curtain airbag inflator; replace the left side curtain airbag (see 
SIDE CURTAIN AIRBAG REPLACEMENT ). 

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

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

simulator lead from the left side wire harness.  

11. Reconnect the negative cable to the battery.  

12. Turn the ignition switch ON (II).  

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

14. Measure the voltage between each terminal of the SRS simulator lead and body ground. There should 

be 0.5 V or less.
