3. Turn the ignition switch ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does

not communicate, troubleshoot the DLC circuit (see DLC CIRCUIT
TROUBLESHOOTING ).

5. In the SRS MENU of the HDS, select SRS, then DTC to clear DTC(s).
6. Turn the ignition switch OFF.

NOTE:

Only read DTCs from the SRS menu, not from the SWS
menu. SWS (ODS unit) DTCs are subcode of SRS unit
DTCs. Only troubleshoot the corresponding SRS DTCs.

NOTE:

Make sure the battery is fully charged before you begin.

CLEAR THE DTC MEMORY USING MES CONNECTOR WITHOUT THE HDS

Special Tools Required

SCS Service Connector 07PAZ-001010A

To clear the DTC(s) from the SRS unit, use the HDS or the following procedure.

1. Make sure the ignition switch is OFF.
2. Connect the SCS service connector (A) to the yellow MES 2P connector (B).

Do not use a jumper wire.

3. Turn the ignition switch ON (II).
4. The SRS indicator will come on for about 6 seconds, and then go off. Remove

the SCS service connector from the MES connector (2P) within 4 seconds after
the indicator goes off.

5. The SRS indicator will come on again. Reconnect the SCS service connector to

the MES connector (2P) within 4 seconds after the indicator comes on.

6. When the SRS indicator goes off, remove the SCS service connector from the

MES connector (2P) within 4 seconds.

7. The SRS indicator blinks two times, indicating that the memory has been

cleared.

8. Turn the ignition switch OFF, and wait for 10 seconds.
9. Turn the ignition switch ON (II) again. If the SRS indicator comes on for 6

seconds, and then goes off, the system is OK.

TROUBLESHOOTING INTERMITTENT FAILURES

If there was a malfunction, but it does not recur, it will be stored in the memory as
an intermittent failure, and the SRS indicator may come on depending on this
malfunction detected.

After checking the DTC, troubleshoot as follows:

1. Make sure the ignition switch is OFF:
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does

not communicate, troubleshoot the DLC circuit (see DLC CIRCUIT
TROUBLESHOOTING ).

5. In the SRS MENU on the HDS, select SRS, then DTC to clear DTC(s).
6. Read the DTC (see "READING THE DTC").
7. Clear the DTC memory (see "CLEAR THE DTC MEMORY").
8. Set the parking brake, then start the engine, and let it idle.
9. The SRS indicator comes on for about 6 seconds and then goes off.

10. Shake the related wire harnesses and the connectors, and look for loose

connections, poor pinfits, and poor grounds.

11. Take a test-drive (quick acceleration, quick braking, and cornering), turn the

steering wheel fully left and right, and hold it there for 5 to 10 seconds. If the
problem recurs, the SRS indicator will come on.

NOTE:

Check the condition of the battery (see BATTERY (EXCEPT
HYBRID) ) and the charging system (see CHARGING
SYSTEM INDICATOR CIRCUIT TROUBLESHOOTING ). Low
battery voltage may cause some intermittent failures.

12. If you cannot duplicate the concern, ask the customer about the conditions

when it occurred, or ask the customer to demonstrate the concern.

13. If you cannot duplicate the intermittent failure, the system is OK at this time.

CHECKING FRONT PASSENGER'S WEIGHT SENSORS AFTER A VEHICLE COLLISION

1. Position the front passenger's seat to the rearmost position, adjust the recliner

to the forward most position. Do not move it from this position.

2. Drive the vehicle, accelerate to 20 mph (36 km/h), then stop on level ground.
3. Make sure the ignition switch is OFF.
4. Connect the HDS to the data link connector (DLC) (A).

5. Turn the ignition switch ON (II).
6. Make sure the HDS communicates with the vehicle and the SRS unit. If it does

not communicate, troubleshoot the DLC circuit (see DLC CIRCUIT
TROUBLESHOOTING ).

7. From the SRS inspection menu, select Seat Weight Sensor, then Misc test, then

"SEAT OUTPUT CHK" and follow the prompts until the front passenger's
weight sensor operation check is complete.

NOTE:

A faulty cable reel can cause intermittent connections
related to the driver's airbag inflator DTCs.
