the instructions and documentation packaged with the DCI
to troubleshoot or reconfigure the EC-17
controller.
For more information on the Bendix Diagnostic
Communication Interface, see your local authorized Bendix
parts outlet or call 1-800-AIR-BRAKE (1-800-247-2725).
OPTIONAL DIAGNOSTIC LEDS & RESET
The condition of specific components is provided by a series
of labeled, light emitting diodes (LEDs) in the EC-17
controller housing. No special tools or equipment are needed
to read or interpret the EC-17
It should be noted that the EC-17
display is separate from the antilock and traction condition
lamps on the dash. With this separation, the driver is aware
of any issues that occur but is not confused by diagnostic
information. There are ten LEDs plus a magnetically actuated
reset switch. The first six LEDs locate an issue to a specific
area of the vehicle, and the next three indicate the component
or its wiring. The LEDs are software driven and are either
ON or OFF depending upon their monitor function. (Note:
right and left, front and rear are determined from the driver's
seat.) Note: The non LED EC-17N
equipped with a magnetic reset.

Note: The MID LED is used with some but not all vehicles.
When six speed sensors are not installed this LED
is not used in the diagnostic process. However, it
™
will light when a magnet is placed on the RESET
switch in the diagnostic display.
"FRT" (Front) LED
This Red LED illuminates in order to indicate the location of
a component or its wiring. It will light in conjunction with
either the RIGHT or LEFT LED and the MOD or SENS LED.
"MID" (Middle Axle) LED
This Red LED is not used in all installations. On those
vehicles that have six speed sensors installed, this Red
LED illuminates to indicate the location of a speed sensor
or its wiring. The "MID" LED should not illuminate with the
"MOD" LED.
