The Bendix+ EC-60 Advanced Controller is a member of a family of electronic Antilock Braking System (ABS) devices designed to help improve the braking characteristics of air braked vehicles - including heavy - and medium-duty buses, trucks, and tractors. ABS controllers are also known as Electronic Control Units (ECUs). In addition to the Antilock Braking System and Automatic Traction Control functions, the EC-60 Advanced Controller models provide ABS-based stability features referred to as ESP+ Electronic Stability Program. The Bendix ESP system is an ABS-based stability system that enhances vehicle stability by both reducing engine throttle and by applying vehicle braking based on actual vehicle dynamics. Accordingly, the ESP system is available only on specific approved vehicle platforms after vehicle application and development efforts and validation testing. Only certain limited variations of an approved vehicle platform are permitted without further validation of the ESP system application. ESP stability system consists of Yaw Control (YC) and Roll Stability Program (RSP) features. \nNote: Cab-mounted EC-60 controllers are not protected against moisture, and must be mounted in an environmentally protected area. Frame-mounted EC-60 controllers may be mounted on the vehicle frame, but only in locations where they will not be subjected to direct tire spray.
