Chapter 2 • Establishing ConnectionConnecting Brake-Link ComponentsConnect Brake-Link to the vehicle with one of the following adapters:• J560 PLC Cable Set. Attach to the tractor or trailer J560 Power LineConnector. Note: The ECU must be configured to support EnhancedPLC Mode in order to use this adapter.• 9-Pin Deutsch. Attach to the Deutsch Connector typically located underthe dash (driver’s side), beside the driver’s seat or near the trailer brakeECU.Choosing the appropriate adapter depends on:• whether you’re diagnosing the Tractor or Trailer;• which connectors are available on the Tractor/Trailer;• whether the Tractor is connected to the Trailer;?Do• whether the ECU is configured to support Enhanced PLC Mode.you know what Enhanced PLC Mode is?Older brake ECUs transmit diagnostic information over the J1708 Bus only(Figure 2.3, page 19)—accessing both tractor and trailer ECUs requiresindependent connections. Newer ECUs offer Enhanced PLC Mode—theycan send diagnostic information over the power line. If the tractor andtrailer are connected, access both ECUs via a single connection.16 NEXIQ Brake-Link Bendix ® & Eaton ® ABS Applications

Connecting Brake-Link ComponentsUse the following table to help you decide which adapter to use with the Bendix® & Eaton ® ABS Applications. Then look at the connection diagram andcomplete the instructions that follow the table.BENDIX & EATON ABS APPlICATIONSAre youtestingthe...TractorOnlyTrailerOnlyTractor/TrailerTogetherConnect to the...If the tractor ECU supports Enhanced PLCMode, connect to either the Deutsch or J560Power Line Connector.If it doesn’t, use the Deutsch Connector.If the trailer ECU supports Enhanced PLCMode, connect to the J560 Power Line; otherwise,connect to the Deutsch if available.If the trailer ECU supports Enhanced PLCMode, connect to the tractor Deutsch to communicatewith both ECUs via a single connection.If it doesn’t, connect to the trailer and tractorseparately via their perspective Deutsch Connectors.Note: Bendix ® Generation 5 controllers (formerly of Eaton ® ) supportEnhanced PLC Mode.

Chapter 2 • Establishing ConnectionEnabling Enhanced PLC ModeABS controllers that are equipped with Enhanced PLC Mode can send diagnosticinformation over the tractor/trailer power lines. This feature makes itpossible to:• access all ECUs residing on the power line via a single diagnostic connection.For example, if the Tractor and Trailer are connected, attachBrake-Link to the Tractor Deutsch to access both Tractor and TrailerABS ECUs.• access a Trailer ABS ECU when a Deutsch Connector isn’t available. Italso makes Trailer ECU access more convenient, as you only need oneadapter (J560 PLC Cable Set) to supply power and communicate withthe ECU.Bendix ® EC-30 and EC-30T controllers may require configuration to enableEnhanced PLC Mode. The rest of this section details enabling EnhancedMode.To enable Enhanced PLC Mode:1 Connect Brake-Link to the Tractor or Trailer Deutsch Connector (see“Connecting Brake-Link Components”, on page 16).Note: Some ECUs support Enhanced Mode configuration over thePLC. In other words, if the trailer is attached to the tractor, you maybe able to configure both ECUs through a single connection to thetractor Deutsch.
