6. All or part of traction control can be lost during self

configuration by;

A. Not connecting one of the wire harnesses (engine

control module for torque limiting and ATR valve
solenoid for differential braking)

B. A missing or inoperative traction dash lamp (bulb

missing or burned out).

C. A missing or inoperative traction control enable

disable switch.

D. Not placing the traction control enable / disable switch

in the disabled position. The operator can tell that
the traction features are lost by noting the absence
of the traction lamp flash upon power up. The operator
should note the flashing of the antilock condition
lamp, and the traction lamp if traction equipped, upon
every power up. Observing the dash lamps is the
only method the operator has to verify the system
operation.

7. The EC-16

controller can be reprogrammed up to 10,000

times.

8. When a replacement EC-16

controller is installed on a

vehicle that does not have one or more of the pre
programmed features, a failure will be registered on the
dash lamp(s) and on the EC-16

controller diagnostic

display. For this reason it is necessary to perform the
self configuring procedure.

9. Some configuration information is available by observing

the reaction of the dash condition lamps on vehicles
configured with traction control and equipped with the
self configuring EC-16

controller. When the ignition is

switched ON, the EC-16

controller self test is begun.

During the self test the dash lamps will flash on and off
together as indicated in the chart, depending upon the
type and amount of traction control configured into the
EC-16

controller. Note: For more information on this

subject see the TROUBLESHOOTING section of this
document.

Self Configuration Process

In order to successfully complete the self configuring process
follow the steps presented.

1. Connect all antilock and traction control wire harnesses.

Refer to the schematic in Figure 4. Make certain that all
the speed sensors present on the vehicle are connected
(H2, H3, J1, J2 on the 30 pin connector and E2, E3, F2,
F3, B2, B3, C2, C3 on the 18 pin connector). If the vehicle
has an electronic engine and traction control torque
limiting is desired the engine control module must be
connected (B2 and B3 on the 30 pin connector). If the
vehicle is equipped with either an ATR-1

or ATR-2

valve,

the solenoid connection must be made to the EC-16

controller (D2 and D3 on the 18 pin connector) in order
to obtain traction control differential braking.

2. If the vehicle is to be configured with traction control, it

must have a traction control dash lamp and a traction
control enable / disable switch. Both the lamp and switch
must be functional. Place the traction control enable/
disable switch in the traction control disabled position
(traction control inoperative).

3. Turn the ignition ON and hold a magnet on the RESET

position of the EC-16

controller diagnostic display until

the LEDs begin to randomly flash then remove the
magnet. If the magnet is not removed during the random
LED flashing a second self configuration may be initiated.
The magnet may have to be held on the RESET for as
long as 20 seconds. When the self configuration process
is complete the EC-16

controller will automatically go

through a self test. During the self test the diagnostic
display will indicate the new configuration as described
under the section entitled EC-16

Controller

Configuration Display. Note: If the EC-16

controller is

being configured with traction control (either torque
limiting, differential braking or both), the traction control
condition dash lamp, will be illuminated as well as the
appropriate LEDs on the EC-16

controller diagnostic

display. The traction control dash lamp will be illuminated
until the traction control enable / disable switch is placed
in the traction control enabled position (traction control
operative).

4. Place the traction control enable / disable switch in the

traction control enabled position (traction control
operative), the traction control dash lamp should be off.

5. Before placing the vehicle in service, verify the

configuration and the system condition by turning the
ignition OFF then ON while observing the EC-16

controller diagnostic display. The diagnostic display
should indicate the desired configuration as described
under the section entitled EC-16

Controller

Configuration Display and no red LEDs should be
illuminated at the end of the self test.

6. If the configuration appears correct but the diagnostic

LEDs indicate a failure somewhere in the system, refer
to the General Configuration Information below and use
the Troubleshooting section of this manual to locate and
repair the problem.

7. If the configuration is incorrect, the process can be

repeated as required. One common error is performing
the self configuration with the traction enable / disable
switch in the wrong position. This will prevent any traction
features from being activated. Note: The traction switch
must be in the disable position to configure traction, but
must be placed in the enable position to allow the traction
lamp to flash.
