Intermittent Simulation
To produce the conditions which create an intermittent fault so that it may be identified during testing, some of the following methods may be used:
- Applying light vibration to components.
- Heating a component.
- Wiggling or bending a wiring harness.
- Applying humidity to a component.
- Remove or apply a vacuum supply source.
Monitor component voltage, or monitor for self-diagnostic codes while attempting to simulate intermittent. Use the results of these tests to identify a faulty component or an area which should be checked closely for the problem.
NOTE:
Intermittent problems are often caused by poor harness connector. It is important to check harness connector contact.
