Reconfi guring EC-60
™
Controllers
SYSTEM CONFIGURATION
The EC-60
™
controller is designed to allow the technician to
change the default system settings (chosen by the vehicle
OEM) to provide additional or customized features. When
replacing an ECU, be sure to use an equivalent Bendix
replacement part number so that the standard default set-
tings are provided.
Depending on the model, the customizable features include
ABS control settings, engine module communication etc.
Many of these settings can be reconfi gured using a hand-
held or PC-based software, such as the Bendix
®
ACom
™
Diagnostics program.
ECU RECONFIGURATION
Reconfi guring Standard ECUs
Reconfi guring an EC-60
™
controller may be carried out by
using the Blink Code Switch or by using a hand-held or
PC-based diagnostic tool.
Note: During the reconfi guration process, and independently
from any reconfi guration being carried out by the technician,
standard ECUs automatically check the J1939 serial link
and communicate with other vehicle modules. In particular,
if the serial link shows that the vehicle has a retarder device
present, the ECU will confi gure itself to communicate with
the retarder device for improved ABS performance. For
example, if the ECU detects the presence of a retarder
disable relay during a reconfi guration, it will confi gure
itself to control the relay to disable the retarding device
as needed.
Reconfi guring Premium ECUs
As with standard ECUs, the Premium EC-60
™
controller
also carries out, independently from any reconfi guration
being carried out by the technician, an automatic check
of the J1939 serial link and communicates with other
vehicle modules. This includes checking for ATC and
retarder disable relay operation. In addition, premium
EC-60
™
controllers will determine the number of wheel
speed sensors and PMVs installed and confi gure itself
accordingly.
6S/5M Confi guration
Premium EC-60
™
controllers will configure for 6S/5M
operation when a reconfi guration event is initiated and
the ECU detects that an additional axle PMV is wired as
follows:
PMV Connector ECU Connector
Hold Right Additional Axle Hold
Release Left Additional Axle Release
Common Right Additional Axle Common
See 6S/5M System Schematics (pages 37 & 40) for
details.
Reconfi guration Using the Blink Code Switch
The reconfi guration event is the same for both Standard
and Premium ECUs. With ignition power removed from the
EC-60
™
controller, depress the blink code switch. After the
ignition power is activated, depress and release the switch
seven times to initiate a reconfi guration event.
Diagnostic Tool
A reconfi guration event may be initiated using a hand-held
or PC-based diagnostic tool to communicate with the ECU
over the SAE J1587 diagnostic link.
