Troubleshooting Intermittent Failures
Troubleshooting Intermittent FailuresIf 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 the malfunction detected.
NOTE: Check the condition of the battery, and the charging system. Low battery voltage may cause some intermittent failures.
After checking the DTC, troubleshoot as follows:
1. Read the DTC.
2. Erase the DTC memory.
3. Set the parking brake, then start the engine, and let it idle.
4. The SRS indicator comes on for about 6 seconds and then goes off.
5. Shake the related wire harness and the connectors, and look for loose connections, poor pin fits, and poor grounds.
6. 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 connectors related to the driver's airbag.
7. If you cannot duplicate the intermittent failure, the system is OK at this time.
