Intermittent Simulation
WARNING: This page is about a different car, the 2001 GMC Safari and 2001 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
Use following methods to reproduce conditions causing intermittent problem(s):
- Apply light vibration to components.
- Apply small amount of heat to component.
- Wiggle or bend wiring harness.
- Remove/apply vacuum supply source.
Monitor circuit/component voltage or resistance while attempting to simulate intermittent. If vehicle is running, monitor for DTCs. Use test results to identify problem component or circuit.
