“RER” (Rear) 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.

“RHT” (Right) 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 FRONT or REAR LED and the MOD or SENS

LED.

“LFT” (Left) 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 FRONT or REAR LED and the MOD or SENS LED.

“TRC” (Traction) LED

This Red LED illuminates to indicate a permanent

diagnostic trouble code in the traction control system. It

may be illuminated with the MOD LED or may illuminate by

itself. NOTE: If a problem may exist with the wiring to the

engine control module (ECM), this LED will go on.

“MOD” (Modulator) LED

This Red LED illuminates to indicate an open or short

circuit in the solenoids of one of the four modulators or

the wiring connecting them to the system. When indicating

a diagnostic trouble code with a modulator this LED will

be illuminated with two positioning LEDs (RHT/LFT +

FRT/RER). NOTE: The MID positioning LED should not

be illuminated with this LED. This LED is also used to

indicate a possible problem with an ATR-1

™

or ATR-2

™

valve, antilock traction relay, solenoid. When illuminated

for a traction system diagnostic trouble code the TRC LED

will also be on.

“SEN” (Speed Sensor) LED

This Red LED illuminates to indicate an open or short circuit

in one of the speed sensors or the wiring connecting them

to the system. The “SEN” LED will be illuminated with two

positioning LEDs (RHT/LFT + FRT/MID/RER).

“ECU” (Electronic Control Unit) LED

This Red LED, when illuminated, indicates that the

controller itself has failed. Before controller replacement is

considered, always check vehicle voltage to the controller.

“VLT” LED

This Green LED illuminates and remains ON during vehicle

operation to indicate that vehicle power is reaching the

controller. If vehicle power is out of range (below 10 VDC or

above 18.0 VDC) this LED will ﬂ ash until power is brought

into range.

“RESET”

Beneath the RESET area of the display is a magnetically

sensitive switch that is used to reset the diagnostic system.

The device will respond to a magnet which has strength

sufﬁ cient to lift a three (3) ounce weight. Momentarily

holding a magnet against the RESET will cause ALL LEDs

to light during the time the magnet is against it. Holding

a magnet against the RESET longer than 20 seconds will

cause the EC-17

™

controller to initiate the self conﬁ guration

feature.

CONTROLLER CONFIGURATION

IMPORTANT GENERAL NOTE:

The following information and procedure applies to the

EC-17

™

controller equipped with the optional LED diagnostic

display and magnetic RESET switch. Controllers without

this option (EC-17N

™

) must use the J1587 diagnostic

link and the DCI with its related computer programs to

reconﬁ gure the controller. See the documentation and

instructions packaged with the equipment for speciﬁ cs.

CONTROLLER CONFIGURATION DISPLAY

1. Turn the ignition ON.

2. All LEDs will illuminate then go out.

3. The number of active sensors will be displayed by the

momentary illumination of the red SEN (sensor) LED

and two or more of the red locating LEDs. No other

LEDs will be on.

A. SEN + FRT (front) + RER (rear) = A four sensor

conﬁ guration (all systems must have at least a 4

sensor conﬁ guration)

B. SEN + FRT + MID (middle) + RER = A six sensor

conﬁ guration

4. The red TRC LED will momentarily illuminate by itself

if traction control torque limiting is active, if not, then

the display will go to the condition described in #5.

5. The red TRC and MOD LEDs will momentarily illuminate

if traction control differential braking is active, if not, then

the display will go to the condition described in #6. No

other LEDs will be on.

6. The diagnostic display will return to its normal

operational status. Assuming no diagnostic trouble

codes exist in the antilock or traction system, all red

LEDs will be off and the single, green, VLT LED is

illuminated.
