Description of defect

In radiator fan controllers, cracks may occur in the solder section during use due to improper soldering of the IC leads. This may result in non-operation or continuous operation of the radiator fan due to poor continuity of the leads. In the worst case scenario, the water temperature gauge may show a high temperature when non-operational.

Improvement details

Replace the fan controller with a countermeasure.
