the entire antilock system including wiring continuity. A dash

lamp, controlled by the EC-14

™

controller, advises the driver

of the condition of the entire antilock system. The condition

of specific antilock components is provided to the mechanic

by a series of labeled, light emitting diodes (LED’s) displayed

through a “window” in the EC-14

™

controller housing. No

special tools or equipment are needed to read or interpret

the EC-14

™

controller diagnostics window. It should be noted

that the diagnostics display is separate from the antilock

condition lamp on the dash. With this separation, the driver

is aware of any problems that occur, but is not concerned

with in-depth diagnostic information.

A special feature of the EC-14

™

controller diagnostic system

is its failure latching. Intermittent problems, particularly in

the wheel speed sensing area can be difficult to diagnose.

When the controller senses an erroneous condition, whether

in the controller electronics, the modulator or speed sensing

areas, it stores the condition in non-volatile memory, disables

the antilock function if necessary, illuminates the dash

mounted antilock condition lamp and the appropriate

diagnostic LEDs on the EC-14

™

controller. The malfunction

condition is truly stored and is not cleared by loss of power

to the EC-14

™

controller. The LEDs will re-light when power

is restored and remain illuminated until the problem is

corrected. After the actual problem is corrected, maintenance

personnel can clear or reset the EC-14

™

controller

diagnostics by passing a small magnet over the RESET

point in the diagnostics window.

DIAGNOSTIC LEDS

There are nine LEDs plus a magnetically actuated reset

switch in the EC-14

™

controller diagnostic window. The first

five LEDs locate a problem to a specific area of the trailer

while the last four indicate the problem component or its

wiring. The LEDs are computer controlled 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.

Left front is therefore the corner closest to the driver.)

LED o MID Red LED (SEE NOTE)

however, it will light when a magnet is placed on the

RESET switch in the diagnostic window.

"FRONT" LED

This Red LED illuminates and latches on in order to indicate

the location of a problem component or its wiring. It will light

in conjunction with either the RIGHT or LEFT LED and the

SENS LED when indicating a speed sensor problem. The

FRONT LED will also light in conjunction with the MOD LED

to indicate that the front modulator (M-21

™

or M-22

™

) or its

wiring has malfunctioned.

"MID" LED

This red LED is not used in troubleshooting the EC-14

™

controller and should light only when a magnet is held on

the RESET switch.

"REAR" LED

This red LED illuminates and latches on in order to indicate

the location of a problem component or its wiring. It will light

in conjunction with either the RIGHT or LEFT LED and the

SENS LED when indicating a speed sensor problem. The

REAR LED will also light in conjunction with the MOD LED

to indicate that the rear modulator (M-12

™

) or its wiring has

malfunctioned.
