Troubleshooting Intermittent Failures

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

Troubleshoot as follows:

1. Read the DTC (see "Reading the DTC").
2. Ask the customer under what conditions the SRS light usually turns on.
3. Check all SRS connectors that are related to the temporary DTC stored in memory, for poor or loose connections.
4. Erase the DTC memory (see "Erasing the DTC Memory").
5. Set the parking brake, then start the engine, and let it idle.
6. The SRS indicator should come on for about 6 seconds and then go off.
7. Shake the related wire harness and the connectors, take a test drive (quick acceleration, quick braking, cornering), turn the steering wheel fully left and right, and hold it there for 5 to 10 seconds. Use the heater or A/C to help match the conditions that the customer described. If the problem recurs, the SRS indicator will come on.
8. If you can't duplicate the intermittent failure, the system is OK at this time.
