and procedures presented in this manual can be used.

When connected to a PC, use the instructions and

documentation packaged with the DCI to troubleshoot or

reconﬁ gure the EC-17

™

/EC-17N

™

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

™

controller

diagnostic display. It should be noted that the EC-17

™

controller diagnostics 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 ﬁ rst

six LEDs locate an issue to a speciﬁ c 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

™

controller is also not equipped with

a magnetic reset.

RESET + No LED

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.

Both the Antilock & Traction dash lamps are

ON during the system self test.

This is the ﬁ rst blink occurrence of the

Antilock dash lamp. Compare and note the

traction lamp’s reaction to the Antilock lamp.

Both dash lamps are OFF and remain OFF

at the end of the powerup sequence.

This is the second blink occurrence of the

Antilock dash lamp. Compare and note the

traction lamp’s reaction to the Antilock lamp.
