Abstract
An ATV or UV without a body control module includes a daytime running light control module. Daytime running lights are turned on when the engine speed, as indicated by the ECU microprocessor, is equal to or greater than a threshold and when each of the standard and bright headlights and right and left turn indicator lights are off. Otherwise the daytime running lights are turned off. If desired, the microcontroller performing the daytime running light control method may be the same microcontroller which controls the starter motor relay.
