The ignition input is applied by the ignition switch through a 5 amp fuse. The battery input is connected through a 30 amp fuse directly to the battery. Failure to properly seat or seal the connectors could result in moisture or corrosion damage to the connector terminals.įrame ECUs utilize Deutsch connectors. All unused connector terminals must be plugged with the appropriate sealing plugs. Frame ECUs Frame-mounted EC controllers may be mounted on the vehicle frame, but only in locations where they will not be subjected to direct tire spray.ĮCU mounting bolts must be torqued to 7. The use of secondary locks is strongly recommended. All wire harness connectors must be properly seated. Traction control valve may be integral to the service brake relay valve or a stand-alone device.Ĭab ECUs Cab-mounted EC controllers are not protected against moisture, and must be mounted in an environmentally protected area. Off-road feature is not available on all models - See Chart 1.

Premium EC controllers have a drag torque control feature which reduces driven-axle wheel slip due to driveline inertia by communicating with the engines controller and increasing the engine torque.Įach sensor is installed with a Bendix Sensor Clamping Sleeve.

Bendix ATC can improve vehicle traction during acceleration, and lateral stability while driving through curves. However, the EC controller is able to pump the brakes on individual wheels or pairs of wheelsindependently, and with greater speed and accuracy than a driver.

When excessive wheel slip, or wheel lock-up, is detected, the EC controller will activate the Pressure Modulator Valves to simulate a driver pumping the brakes. By monitoring individual wheel turning motion during braking, and adjusting or pulsing the brake pressure at each wheel, the EC controller is able to optimize slip between the tire and the road surface.
