The EC-30 ™ controller can be assembled on one of four different valve models. The EC-30 ™ controller can be bracket mounted to the vehicle cab or chassis as a stand alone ECU. The ABS warning lamp for EC-17 ™ and EC-16 ™ controllers, at power-up without faults, will illuminate for approximately 8 seconds and flash twice before turning off.ĬHART 1 - ECU DIFFERENCES (EC-30 ™, EC-17 ™, EC-16 ™ CONTROLLERS) The EC-30 ™ controllerABS warning lamp, at power-up without faults, will illuminate for 2.5 seconds and then turn off. The EC-30 ™ controllerABS warning lamp power-up sequence has been simplified compared to the EC-17 ™ and EC-16 ™ controllers. The EC-16 ™ controller utilizes a totally metal enclosure. However, the EC-30 ™ controller utilizes plastic mounting inserts to reduce mounting bolt corrosion, where the EC-17 ™ controller utilizes metal mounting inserts. The EC-30 ™ controller has a black plastic enclosure similar to the EC-17 ™ controller.

The EC-30 ™ controller has been designed to replace the EC-17 ™ and the EC-16 ™ controllers as the standard Bendix ABS controller for OEM and aftermarket installations. The EC-30 ™ controller utilizes a 30-pin and an 18-pin wire harness to interface with ABS, ATC and vehicle system components.ĮC-30 ™ Controller Comparison to EC-16 ™ and EC-17 ™ Controllers The design of the EC-30 ™ controller electronics is robust against radio, electromagnetic and environmental interference.Ī patented LED (light emitting diode) diagnostic display and magnetic reset switch are incorporated in the housing for simple, self-contained diagnostics. The EC-30 ™ controller electronics are contained in a nonmetallic housing and are environmentally protected by a hard epoxy potting compound.
