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 ).
