Simulation Test
Sometimes the most difficult case in troubleshooting is that the problem symptom occurred previously does not appear again. In such case, this simulation test is used effectively for repairing intermittent malfunctions.
- Vibration
- Slightly shake the connector and wiring harness up and down and right and left.
- Slightly Vibrate sensors or actuators.
- Heat
- Heat components that likely caused the malfunction with a hair dryer or others.
- Do not heat the components to the point where they may be damaged and do not heat the ECM directly.
- Water sprinkling
- Sprinkle water onto vehicle to simulate a rainy day or a high humidity condition.
- In this test, do not sprinkle water directly onto the engine compartment or electronic components.
- Electrical loads
- Turn on all electrical systems to simulate excessive electrical loads.
