If your power steering system is not functioning properly, it could be due to a faulty control module. Symptoms may include excessive steering effort, erratic power steering assist, or even a complete loss of power steering. Replacing the Honda 39980-S5T-A011-M1 power steering control module can help alleviate these issues and restore the proper functioning of your power steering system.
