FAN CONTROL MODULE INSPECTION [SKYACTIV-X 2.0]

id0112hf801100

Note

• The fan control module cannot be removed as a single unit. If the fan control module is replaced, replace the cooling fan component.

1. Connect the M-MDS to the DLC-2.

2. Start and warm up the engine.

3. Display PID FAN and simulation item FAN using the M-MDS. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [PCM (SKYACTIV-X)].)(See SIMULATION INSPECTION.)(See SIMULATION TABLE [PCM (SKYACTIV-X)].)

4. Using the simulation function, gradually increase the FAN value from 0% to the maximum value and visually verify that the cooling fan operation speed changes.

Note

• To start the cooling fan from the stopped condition, approx. 4 s. are needed for start-up preparations before starting the cooling fan.

5. Using the M-MDS, verify that the cooling fan operates normally while measuring the ECT sensor No.1 value under the following conditions.

Fan control module

Engine coolant temperature detected by ECT sensor No.1 [°C {°F}]	Cooling fan operation
less than 106 {223}	OFF
106—108 {223—226}	ON
more than 108 {226}	ON

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.
