Intermittent Simulation
WARNING: This page does not describe the selected car, but rather 35 other vehicles, including the 1992 Pontiac Trans Sport, 1992 Oldsmobile Silhouette, 1992 Oldsmobile Bravada, 1992 GMC Yukon, and 1992 GMC Vandura Special. However, it is still accessible from the selected car via links, so may be relevant.
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.
