Is the resistance as specified?

YES - Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the
connection; if the connection is OK, replace the SRS unit (see SRS UNIT REPLACEMENT ).

NO - Open or increased resistance in the right side wire harness; replace the right side wire harness.

DTC 22-3X ("X" CAN BE 0 THRU 9 OR A THRU F): SHORT TO ANOTHER WIRE OR
DECREASED RESISTANCE IN FRONT PASSENGER'S SEAT BELT TENSIONER

Special Tools Required



SRS inflator simulator 07SAZ-TB4011A



SRS simulator lead F 07XAZ-SZ30100

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 22-31 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 right side wire harness 4P connector (A) from the front passenger's seat belt tensioner.

NOTE:

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

harness.

6. Reconnect the negative cable to the battery.

7. Clear the DTC memory.

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

Is DTC 22-3x indicated?

YES - Go to step 9.

NO - Short in the front passenger's seat belt tensioner; replace the front passenger's seat belt (see
FRONT SEAT BELT REPLACEMENT ).

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

10. Disconnect the driver's seat belt tensioner connector (see step 6 ).

11. Disconnect SRS unit connector B (28P) from the SRS unit (see step 7 ).

12. Disconnect the simulator lead from the right side wire harness.

13. Measure the resistance between the No. 3 and the No. 4 terminals of SRS unit connector B (28P).

There should be an open circuit or at least 1 M ohms.
