Selecting a Protocol & Registering the ECU

NEXIQ Brake-Link™ Bendix

& Eaton

ABS Applications 21

Both

Bendix

and Eaton

ABS Applications require you to select a hardware/

communication protocol in order to establish a connection to the ECU. In other

words, you must tell Brake-Link™ which Data Bus to use for communications:

J1708/J1587 BUS

PLC/ENHANCED MODE

. Use the following table to help

you decide which protocol best suites your needs.

J1708/

J1587

Benefits:

• provides ECU access via a standard Deutsch con-

nection

• supported by all Bendix

brake ECUs

Considerations:

• ECU access typically requires connecting to the

tractor and trailer separately

• some

trailers

do not provide Deutsch connectors

• if you’re diagnosing a trailer that

isn’t

connected to a

tractor, an external power supply and adapter is re-

quired in

addition

to the Deutsch adapter

Use if:

• the ECU you’re testing doesn’t support Enhanced

PLC Mode, i.e., Gen 4 or EC-17

• the ECU you’re testing supports, but is not config-

ured for, Enhanced PLC Mode; once you enable it,

you can use either protocol

PLC/

Enhanced

Mode

Benefits:

• provides ECU access via a Deutsch

J560 Power

Line Connection

• if the tractor is attached to the trailer, it provides ac-

cess to both ECUs via a single connection

• provides access to the

trailer

ECU if there is no

Deutsch Connector available

Considerations:

• the applicable ECU(s) must support Enhanced PLC

Mode (see pg. 30) to utilize this protocol

Use if:

• the tractor is connected to the trailer and you need

to communicate with the trailer or both ECUs

• there is no Deutsch Connector available on the trail-

• you’re testing a trailer that is not connected to a trac-

tor
