Intermittent Simulation

To reproduce conditions creating an intermittent problem, use following methods

  1. Lightly vibrate component.
  2. Carefully heat component using a hair dryer.
  3. Wiggle or bend wiring harness.
  4. Spray component with water mist.
  5. Remove/apply vacuum source.

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