Intermittent Simulation Tests

Consider the following conditions to recreate an intermittent malfunction:

• Drive vehicle on rough road or with engine vibrating at idle (with A/C on).
• Incident occurs on only extremely hot or cold days.
• Water may intrude into connectors and cause corrosion between connector terminals.
• Operate multiple accessories (P/W, P/L, A/C, wipers, lights, etc.).
• Start vehicle either hot or cold.
• Wiring harnesses may be checked by gently wiggling wire harness during testing. Relays and sensors may be checked by gently tapping during testing.
