id0112t1801100

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. Gradually increase the FAN value from 0 to the maximum possible M-MDS operation value using the simulation function. (See SIMULATION INSPECTION.)(See SIMULATION TABLE [PCM (SKYACTIV-D)].)

• Visually verify that the operation speed of the cooling fan conforms to the override drive.

Note

• To start the cooling fan from the stopped condition, approx. 5 s. are needed for start-up preparations before starting the cooling fan.

5. Using the M-MDS, change the operation condition of the engine coolant temperature under the following conditions, and verify that the cooling fan operates correctly.

Engine coolant temperature °C {°F}

Cooling fan operation status

less than 98 {208}

0%

100—108 {212—226}

15%

more than 108 {226}

86%

Engine coolant temperature °C {°F}	Cooling fan operation status
less than 98 {208}	0%
100—108 {212—226}	15%
more than 108 {226}	86%

6. If normal operation cannot be verified in Steps 4 and 5, inspect the input signals of the following parts. Replace the cooling fan motor if all the following parts are normal.

• ECT sensor
