Intermittent Simulation

Following methods may reproduce conditions which create an intermittent fault so fault may be identified during testing:

• Applying light vibration to components.
• Heating a component.
• Wiggling or bending a wiring harness.
• Applying humidity to a component.
• Removing or applying 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 results of these tests to identify a faulty component or an area which should be closely checked for problem.
