Monitor GDS Data

1. Connect GDS to Data Link Connector (DLC).
2. Warm up the engine to normal operating temperature.
3. Monitor the "IATS" parameters on the GDS.




The output signals of IATS & ECTS change smoothly without any rapid changes. Those have almost same characteristic signal during the early period after start. It means that the temperatures of intake air and engine coolant are depended on the temperature of atmosphere. Meanwhile, during the warming up, the output signal of ECTS is going up increasingly. but, the output signal of IATS changes a little bit. even it may not change almost. It means that the heat of engine does not affect on the temperature of intake air.
4. Is parameter displayed within specifications?
