How the Bendix® TRDU™ Tool Operates
When the TRDU™ tool is plugged into the adapter, and the adapter/TRDU™ tool is installed between the trailer connector and the J560 connector of the towing vehicle, all the LEDs will illuminate, and the green LED will flash 4 times to indicate communications have been established.

Additionally, it is recommended at the end of any inspection that the user switches off and restores the power to the ABS ECU, then check the ABS Indicator Lamp operation and TRDU™ tool to see if they indicate any remaining Diagnostic Trouble Codes.
