Getting Started
Brake-Link™ is a multi-faceted, hand-held, brake system diagnostic tool that offers
a variety of utilities, diagnostic applications and configuration options.
Component connection procedures and navigation vary depending on the utility or
application you’re using. Since this manual details the Meritor WABCO ABS Ap-
plication, the connection and navigation sections are specific to the
Meritor WABCO ABS Application.
Refer to the:
Introducing Brake-Link™ Operator’s Manual for:
—A list of safety warnings and cautions
—An overview of the documentation
—A formal introduction to Brake-Link™
—General Brake-Link™ connection instructions
—General navigation information
—GENERIC PLC TEST and RP1210A PC LINK option details
—Warranty and service information

Safety Warnings & Cautions
To protect yourself from injury and the test vehicle from damage:
Always wear approved eye protection.
Always refer to and follow the vehicle manufacturer’s WARNINGS, CAU-
TIONS and service procedures.
Exhaust gas contains deadly poison. Always test outdoors or use prop-
erly vented exhaust hose.
Keep yourself and your test equipment clear of all moving or hot engine
parts.
Unless otherwise noted, set the parking brake and place the gear selec-
tor in the NEUTRAL or PARK position. If the vehicle has an automatic
parking brake release, temporarily disconnect the release mechanism.
Also, block the drive wheels before performing a test with the engine
running.
Unless otherwise directed, turn the ignition switch OFF before discon-
necting or connecting any electrical components.
Read and understand the user manual for your iPAQ Pocket PC, as well
as this manual before operating your Brake-Link™.
NEXIQ Technologies recommends having an assistant drive the vehicle
while you use the Brake-Link™ to perform vehicle road testing.
Never leave the vehicle unattended while testing.
Certain Electro-Static Discharge (ESD) and/or Electrical Fast Tran-
sient (EFT) events may lock up the Brake-Link™. Disconnect the
Brake-Link™ from the power source and re-connect to regain full
operation.

Chapter 1• Getting Started
Using This Manual
This manual contains comprehensive information to teach you how to use the
Meritor WABCO ABS Application. It also provides the following features to support
quick reference once you’re familiar with the application.
• A detailed Table of Contents to help you find exactly what you’re looking
for quickly and easily
•All-inclusive discussions to minimize referencing other sections
•Comprehensive illustrations to help you visualize concepts
•Troubleshooting Tips to help you solve or avoid common issues
Additionally, each chapter begins with an “at-a-glance” list of the chapter’s con-
tents, along with corresponding page numbers.
Specialized Text
This manual features the following specially formatted text to help you differentiate
software elements presented by the Brake-Link™.
•Menu items: Whenever the manual instructs you to select from a list of
menu items, it presents the desired choice with the formatting you see
here, e.g., “From the main menu, select J1708/J1587 BUS.”
•Screen titles: Once you select a menu item, Brake-Link™ presents the
selected item’s screen. A screen may display information or present an-
other list of menu items. The screen title appears in bolded type, e.g.,
“From the Protocol Selection menu, select PLC/ENHANCED MODE.”
•Field/Line: The manual presents a field or line of text from a display with
this formatting. For instance, “The Request Lamp line updates to reflect
the current request.”
•Emphasis: This format draws your attention to particularly important
information.
Navigation Icons
Brake-Link™ offers two methods of navigation: menu and direct access
buttons. See “Navigating Brake-Link™”, on page 9. If a task can be performed
with both, the manual provides separate instructions for each method. Topic intro-
ductions indicate when there are two sets of instructions and the following icons
help you easily locate the desired set.

Chapter 1• Getting Started
Connecting Brake-Link™ Components
Brake-Link™ interfaces with the vehicle’s ECU(s) via:
• The 6-pin or 9-pin Deutsch connector, typically located under the dash,
beside the driver’s seat or near the trailer’s brake ECU.
or
• The J560 power line connector on the outside of the tractor or trailer.
Determining which connector (and adapter) to use with this application depends
on:
• Whether the tractor is connected to the trailer.
• Whether the trailer ECU supports Enhanced Power Line Carrier (PLC)
Mode.
?Do you know what Enhanced PLC Mode is?
Older brake ECUs transmit diagnostic information over the J1708 Bus
only—accessing both tractor and trailer brake ECUs requires independent
connections. Newer ECUs offer Enhanced PLC Mode—they can send
diagnostic information over the power line. If the tractor and trailer are con-
nected, access both ECUs via a single connection. See “Selecting a
Protocol”, on page 16, for a bus diagram and more information.

- Connecting Brake-Link™ Components
Brake-Link™ Meritor WABCO ABS Application 7
Use the following table to help you decide which connector (and adapter) to use
with the Meritor WABCO ABS Application. Then look at the connection diagram
and complete the instructions that follow the table.
NOTE:
iMeritor WABCO Enhanced Easy-Stop™ (TCS II) supports Enhanced
PLC Mode; Easy-Stop™ (TCS I) does not.
Figure 1.2 shows how to connect Brake-Link™ components for standard ABS
diagnostics.

Chapter 1• Getting Started
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.
To connect Brake-Link™ components and power-up:
1Attach the Power/Data Cable DB15 Connector to the data port (labelled To
Vehi cle) on the Brake-Link™; tighten the thumbscrews.
2Plug the Data Cable Atari End into the Atari End on the cable you attach to the
vehicle, i.e., Deutsch adapter or J560 PLC Cable Set.
3Attach the vehicle interface cable to the vehicle.
—If you’re using the J560 PLC Cable Set, plug into the power line connector
on the outside of the trailer.
—If you’re using the Deutsch Adapter, plug into the Deutsch connector typi-
cally located under the dash on the driver’s side, beside the driver’s seat
or near the brake ECU on the trailer.
NOTE:
iThe trailer ECU must support Enhanced PLC Mode to use trailer power
line or tractor Deustch connectors.
4If you’re using the J560 PLC Cable Set to attach to the trailer, connect the
alligator clips to an external power supply; otherwise, turn the tractor’s key
to the “on” position.
