1. Verify that battery voltage is 12.4 V or more.

• If it cannot be verified, charge the battery or contact an external power supply to the vehicle.
2. Connect the WDS or equivalent to the DLC-2.

3. Turn the ignition switch to the ON position.

Note
• The cooling fan does not operate if the duty value of the fan control signal is 10 % or less, or 95 % or more.
• The range of the duty value of the fan control signal which the simulation function can control is 10 %-90 %.
• Due to the cooling fan protection function, there is a time lag until the fan control signal reaches the specified duty value. (Example: If a fan control signal with a 90 % duty value is input while the cooling fan is stopped, it takes approx. 14 s until the fan speed increases and stabilizes.)
4. Using the "FAN DUTY" simulation function, input fan control signals with duty values of 20 %, 40 %, 60 %, and 80 % at 30 s intervals and verify that the cooling fan operation speed increases.

• If the cooling fan does not operate, inspect the following:
- Open or short circuit in fan control module power supply
- Open or short circuit in fan control module ground
- Open or short circuit in the wiring harness between fan control module terminal B and PCM terminal 1AP (ZJ, Z6) / 1W (LF).
• If the wiring harnesses and connectors are normal, inspect the cooling fan component.
• If the cooling fan operation speed does not increase, replace the cooling fan component.
