Intermittent Simulation

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

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

Monitor circuit/component voltage or resistance while attempting to simulate intermittent. If engine is running, monitor for self-diagnostic codes. See appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section. Use the results to identify a faulty component or circuit.

NOTE: For information on connecting test equipment, see appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section.
