FAN CONTROL MODULE INSPECTION [SKYACTIV-G 2.0]
1. Connect the M-MDS to the DLC-2.
2. Start and warm up the engine.
3. Monitor the engine coolant temperature with the M-MDS.
4. Using the simulation function, gradually increase the FAN_DUTY value from 0% to 100%. (See PCM INSPECTION [SKYACTIV-G 2.0].)
5. Using the M-MDS, change the operation condition of the A/C while measuring the engine coolant temperature under the following conditions, and verify that the cooling fan operates correctly.
|
Engine coolant temperature (°C {°F}) |
A/C operation status |
