Wiper System
SPEED SENSITIVE INTERMITTENT WIPERSThe AN truck equipped with a highline CTM will utilize speed sensitive intermittent wipers. Only a highline CTM will be able to support this feature. A base CTM will provide for intermittent wipers without the speed sensitive feature. The low and high speeds are controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as selected by the driver, an immediate wipe of the windshield takes place and the new delay interval is implemented.
