  • Page 27 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 or PLC/ENHANCED MODE . Use the following table to help you decide which protocol best suites your needs.

    • Establishing Connection Chapter Once you connect Brake-Link™ to the vehicle, choose the application, select a navigation method & hardware/communication protocol, Brake-Link™ at- tempts to establish communication with the ECU. This process is called ECU registration. The discussions in Chapter 3 & 4 assume that you have registered the ECU.
