Powerful ABS troubleshooting for tractors
in a portable package
Small, Simple, Powerful
The Bendix® RDU is a small, portable diagnostic tool for
troubleshooting Bendix® tractor based ABS systems. The unit
simply attaches to the vehicle’s 9-pin diagnostic connector
and the LEDs illuminate to direct you to the component
that needs attention. No blink codes. No handhelds.
No computers. No complicated instructions. Just fast and easy
Easy to Use: The RDU is intuitive and easy to use so your
maintenance staff can spend less time learning how to work
with the tool and more time fixing the problem.
Low Cost: The original patent pending design provides
exceptional functionality at a very affordable price. Eliminate
tool sharing by putting an RDU in every toolbox.
Compact Size: It’s only 11/2” in diameter by 15/8” tall. And
because it’s portable, you can use it in the shop or take it
wherever you need to go.
Compatible: The flexible Bendix® RDU supports the complete
range of Bendix ABS components, including the
Bendix® EC-60™, EC-30™, EC-17, Gen 5, and Gen 4 Electronic
Control Units (ECUs).
How the Bendix RDU Works
The Bendix® RDU simply plugs into the 9-pin diagnostic
connector in the cab of the vehicle. The green LED will flash
four times to indicate communications have been established.
If the ABS system has no active trouble codes or faults, only the
green VLT LED will remain lit to indicate that the system is
receiving the proper voltage. If the ABS system has at least
one active trouble code/fault, the red LEDs will light up
to indicate the malfunctioning ABS component and its
location on the vehicle.
