Technical Description (Comment)
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
If the intermittent wiper interval does not depend on the vehicle speed, the input circuit of the vehicle speed signal (combination meter) and the ETACS-ECU may be defective. Alternatively, the vehicle speed-dependent wiper may be set to "disabled" by using the customization function.
