Checking the component and wiring

1. Ignition off. CAUTION: Avoid touching the pins in the control module and the corresponding connector on the cable harness. There is a risk of static discharge which could damage the control module. Discharge yourself and tools to be used by holding the tool's metal part and touching a body part on the car just before starting to work. If the engine cooling fan (FC) cannot be activated at any speed: Check the fuse, power supply cable and ground lead for the engine cooling fan (FC).
