Intermittent Simulation

To reproduce 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 circuit/component voltage or resistance while attempting to simulate intermittent. If vehicle is running, monitor for self-diagnostic codes. Use the results of these tests to identify a faulty component or an area which should be checked closely for the problem.
