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:

• Lightly vibrate components.
• Heat a component.
• Wiggle or bend wiring harness.
• Spray component with water mist.
• Remove/apply vacuum supply source.

Monitor circuit/component voltage or resistance while attempting to reproduce an intermittent. If engine is running, monitor for self-diagnostic codes. Use the results of these tests to identify a faulty component or circuit.
