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:
   • '04-06 models (see DLC CIRCUIT TROUBLESHOOTING )
   • '07-08 models (see '07-08 MODELS )
5. In the SRS MENU on the HDS, select SRS, then DTC to clear DTCs.
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: A faulty cable reel can cause intermittent connections related to the driver's airbag inflator DTCs.
12. If you can not 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.
