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 33-1 x or 33-2x indicated?  

YES - Go to step 9. 

NO - Open or increased resistance 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 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 the terminals of the SRS simulator lead. There should be 1.0 ohms or 

less.

Is the resistance as specified?  

YES - Open or increased resistance in 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 33-3X ("X" CAN BE 0 THRU 9 OR A THRU F): SHORT TO ANOTHER WIRE OR 
DECREASED RESISTANCE IN LEFT SIDE CURTAIN AIRBAG INFLATOR 

Special Tools Required  



SRS inflator simulator 07SAZ-TB4011A  



SRS simulator lead E 07XAZ-S1A0200  



SRS simulator lead F 07XAZ-SZ30100  



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 33-3x 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 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 ).
