• Getting Started Chapter Getting Started Brake-Link™ is a multi-faceted, hand-held, ABS diagnostic tool that offers a variety of utilities, diagnostic applications, and configuration options. Figure 1.1 Brake-Link™ Component connection procedures and navigation vary depending on the utility or application you’re using. The connection and navigation sections in this manual are specific to the Haldex Trailer ABS Application .
Read and understand 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 Transient (EFT) events may lock up the Brake-Link™.
• Menu items : Whenever the manual instructs you to select from a list of menu items, it presents the desired choice with this format. • Screen titles : Once you select a menu item, Brake-Link™ presents the selected item’s screen. The screen title appears in bolded type.
Navigation Icons Brake-Link™ offers two methods of navigation: menu and direct access buttons. See “Navigating Brake-Link™”, on page 8. If a task can be performed with both methods, the manual provides separate instructions for each method. Topic introductions indicate when there are two sets of instructions and the following icons help you to easily locate the desired set.
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.
Page 12
To connect Brake-Link™ components and power-up: Attach the Power/Data Cable DB15 Connector to the data port (labeled To Vehicle) on the Brake-Link™; tighten the thumbscrews. Plug the Data Cable Atari End into the Atari End on the vehicle interface cable (i.e. Deutsch adapter or J560 PLC Cable Set).
