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: Make sure the battery connections are good and the battery is sufficiently charged.
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 comes on for about 6 seconds and then goes off.
5. Shake the related wire harnesses and the connectors, and check for loose connections, poor pinfits, 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 DTCs related to the driver's airbag.
7. If you cannot duplicate the intermittent failure, the system is OK at this time.
Checking the Front Passenger's Weight Sensors after a Vehicle Collision
1. Position the front passenger's seat to the rear most position, adjust the recliner to the most forward position. Do not move the seat from this position.
2. Drive the vehicle, accelerate to 20 mph (36 km/h), then stop on level ground.
3. Connect the HDS to the data link connector (DLC) (A).
4. From the SRS inspection menu, select Seat Weight Sensor, then Misc Test, then "SEAT OUTPUT CHK." and follow the prompts until the ODS operation check has been completed.
