Reconfiguring 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 reconfigured using a hand-
held or PC-based software, such as the Bendix
®
ACom
™
Diagnostics program.
ECU RECONFIGURATION
Reconfiguring Standard ECUs
Reconfigurating 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 reconfiguration process, and independently
from any reconfiguration 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 configure 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 reconfiguration, it will configure itself
to control the relay to disable the retarding device as needed.
Reconfiguring Premium ECUs
As with standard ECUs, the Premium EC-60
™
controller
also carries out, independently from any reconfiguration
being carried out by the technician, an automatic check of
the J1939 serial link and communicate 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 configure itself accordingly.
6S/5M Configuration
Premium EC-60
™
controllers will configure for 6S/5M
operation when a reconfiguration 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.
Reconfiguration Using the Blink Code Switch
The reconfiguration 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 reconfiguration event.
Diagnostic Tool
A reconfiguration event may be initiated using a hand-held
or PC-based diagnostic tool to communicate with the ECU
over the SAE J1587 diagnostic link.
