2 Establishing Connection uConnecting Brake-Link™ Components, page 16 uSelecting a Protocol & Registering the ECU, page 19 uEnabling Enhanced PLC Mode, page 30 N EXIQ Brake-Link™ offers a variety of connection options. Quickly and easily attach Brake-Link™ to the vehicle, power up and register the ECU to begin a diagnostic session. This chapter details each step necessary to establish communication with the ABS ECU.
Chapter 2 • Establishing Connection Connecting Brake-Link™ Components Connect Brake-Link™ to the vehicle with one of the following adapters: • J560 PLC Cable Set. Attach to the tractor or trailer J560 Power Line Connector. Note: The ECU must be configured to support Enhanced PLC Mode in order to use this adapter. • 9-Pin Deutsch. Attach to the Deutsch Connector typically located under the dash (driver’s side), beside the driver’s seat or near the trailer brake ECU.
Connecting Brake-Link™ Components Use the following table to help you decide which adapter to use with the Bendix® & Eaton® ABS Applications. Then look at the connection diagram and complete the instructions that follow the table. BENDIX & EATON ABS APPlICATIONS Are you testing the... Connect to the... Tractor Only If the tractor ECU supports Enhanced PLC Mode, connect to either the Deutsch or J560 Power Line Connector. If it doesn’t, use the Deutsch Connector.
Chapter 2 • Establishing Connection Figure 2.1 shows how to connect Brake-Link™ components for standard ABS diagnostics. Power/ Data Cable 6- or 9-Pin Deutsch Note: Where applicable, substitute with J560 PLC Cable Set (Figure 2.2) Figure 2.1 Connectivity diagram for standard ABS diagnostics. Use the J560 PLC Cable Set in place of the Deutsch adapter if you plan to attach to the tractor or trailer’s power line connector. Quick Disconnect Figure 2.
