COMPONENTS

The EC-60™controller’s ABS function utilizes the following components:

•Bendix® WS-24™wheel speed sensors (4 or 6, depending on ECU model and configuration). Each sensor is installed with a Bendix Sensor Clamping Sleeve

•Bendix® M-32™or M-32QR™Pressure Modulator Valves (4, 5, or 6 depending on ECU model and configuration)

•Dash-mounted tractor ABS Indicator Lamp

•Service brake relay valve

•Dash-mounted trailer ABS Indicator Lamp (used on all towing vehicles manufactured after March 1, 2001)

•Optional blink code activation switch

•Optional ABS off-road switch. (Off-road feature is not available on all models - See Chart 1.)

The EC-60™controller ATC function utilizes the following additional components:

•Traction control valve (may be integral to the service brake relay valve or a stand-alone device)

•Dash-mounted ATC status/indicator lamp

•J1939 serial communication to engine control module

•Stop lamp switch input (may be provided using the ECU hardware input or J1939)

•Optional ATC off-road switch

ECU MOUNTING

Cab ECUs

Cab-mounted EC-60™controllers are not protected against moisture, and must be mounted in an environmentally protected area.

All wire harness connectors must be properly seated. The use of secondary locks is strongly recommended.

CAUTION: All unused ECU connectors must be covered and receive any necessary protection from moisture, etc.

Cab ECUs utilize connectors from the AMP MCP 2.8 product family.

Frame ECUs

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. ECU mounting bolts must be torqued to 7.5 to 9 Nm.

CAUTION: The frame wire harness connectors must be properly seated with the seals intact (undamaged). All unused connector terminals must be plugged with the appropriate sealing plugs. Failure to properly seat or seal the connectors could result in moisture or corrosion damage to the connector terminals. ECUs damaged by moisture and/or corrosion are not covered under the Bendix warranty.

Frame ECUs utilize Deutsch connectors.
