Intermittent Simulation

To reproduce the conditions creating an intermittent fault, use the following methods:

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

  Monitor circuit/component voltage or resistance while simulating intermittent fault. If engine is running, monitor for self-diagnostic codes. Use test results to identify a faulty component or circuit.
