October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Intermittent Simulation

To reproduce conditions creating an intermittent fault, use 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 diagnostic trouble codes. Use test results to identify a faulty component or circuit.
