Intermittent Simulation

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

• Lightly vibrate component. See VIBRATION METHOD  .
• Heat component. See HEATING METHOD  .
• Wiggle or bend wiring harness. See VIBRATION METHOD  .
• Spray component with water. See WATER SPRINKLING METHOD  .
• Remove vacuum from component.
• Apply vacuum to component. Monitor circuit/component voltage or resistance while simulating intermittent. If engine is running, monitor for Diagnostic Trouble Codes (DTCs). Use test results to identify a faulty component or circuit.
• If malfunction seems to occur when electrical load is high, turn on all electrical equipment including heater blower, headlights, rear window defogger, etc. and check of malfunction occurs.
