How the Bendix
®
(T
RDU ™ ) 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 four (4) times
to indicate communications have been established.
If the ABS Electronic Control Unit (ECU) has no active
Diagnostic Trouble Codes (DTCs), only the green LED will
remain illuminated.
If the ABS ECU has at least one active DTC the TRDU
tool displays the first DTC by illuminating the red LEDs,
indicating the malfunctioning ABS component and its
location on the vehicle. (See Figure 13.) If there are
multiple DTCs on the ABS system, the TRDU tool will
display one diagnostic trouble code first, then once that
DTC has been repaired and cleared, the next code will
be displayed.
The TRDU tool repeatedly blinks out the mileage stored
once communications have been established. By counting
the sequence of blinks and/or strobes on the blue LED the
odometer reading is given. See Odometer Function on
page 8 for more details.

To pinpoint the root cause and to ensure the system
diagnostic trouble code is properly corrected the first time,
additional troubleshooting may be necessary.

Bendix TRDU Tool Reset Function
The magnetic reset switch is located by the letter "B" in
the Bendix logo on the top of the TRDU tool. Activation
J560
requires a magnet with 30 gauss minimum.
The reset operations are:
1. If the magnet is held over the switch for less than six (6)
seconds the "clear diagnostic trouble codes" command
is sent.
2. If the magnet is held over the switch for more than six
(6) seconds, but less than 11 seconds, the Bendix
"self-configuration command" is sent.
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.
