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 this manual before operating your NEXIQ
Brake-Link™.
✔NEXIQ Technologies recommends having an assistant drive the vehicle
while you use the NEXIQ Brake-Link™ to perform vehicle road testing.
✔Never leave the vehicle unattended while testing.
Certain Electro-Static Discharge (ESD) and/or Electrical Fast Transient
(EFT) events may lock up the NEXIQ Brake-Link™. Disconnect the NEXIQ
Brake-Link™ from the power source and re-connect to regain full
operation.

Manual Icons
This manual uses icons to denote specific types of peripheral information.
Connecting 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.
The brake controllers
supported by this application transmit information over
the vehicle’s power lines. If the trailer is connected to the tractor, attach
Brake-Link™ to the tractor’s Deutsch connector; otherwise, attach to the trail-
er’s power line with the J560 PLC Cable Set.

Figure 1.2 shows how to connect NEXIQ Brake-Link™ components for ABS
diagnostics.
Use the J560 PLC Cable Set in place of the Deutsch adapter if you’re connect-
ing to the trailer’s Power Line.
To connect Brake-Link™ components and power-up:
1Attach the Power/Data Cable DB15 Connector to the data port (labelled
To Vehicle) on the Brake-Link™; tighten the thumbscrews.

—If you’re using the J560 PLC Cable Set, plug into the power line con-
nector on the outside of the trailer.
—If you’re using the Deutsch Adapter, plug into the Deutsch connector
typically located under the dash on the driver’s side, beside the
driver’s seat.
Note: If the trailer is connected to the tractor, you can attach
Brake-Link™ to the tractor or trailer Deutsch connectors.

This process is called
registration . Each procedure in this chapter assumes
you’ve connected Brake-Link™ to the tractor/trailer, selected a navigation
method and registered the ECU.
To register the ECU & select a navigation method:
1Connect Brake-Link™ to the tractor or trailer and power-up (see “Con-
necting Components”, on page 5). Brake-Link™ boots up and presents
the Select Application screen.
Use the and keys to select WABASH NATIONAL ABS;
