How to Troubleshoot the SRS - Troubleshooting Intermittent Failures

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 comes on depending on the malfunction detected.

After checking the DTC, troubleshoot as follows:

1.Read the DTC (see ‘‘Reading the DTC'').

2.Erase the DTC memory (see ‘‘Erasing the DTC Memory'').

3.Set the parking brake, then start the engine, and let it idle.

4.The SRS indicator will come on for about 6 seconds and then go off.

5.Shake the 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. If the problem recurs, the SRS indicator will come on.

6.If you can't duplicate the intermittent failure, the system is OK at this time.
