SYSTEM RECONFIGURATION
The Bendix
®
ESP
®
EC‑80
™
Controller is designed to
allow the technician to change the default system settings
(chosen by the vehicle OEM) to provide additional or
customized features.
Depending on the model, the customizable features include
ABS control settings, engine module communication etc.
Many of these settings can be recongured using a hand‑
held or PC‑based software, such as the Bendix
®
ACom
®
Diagnostic software.
ECU RECONFIGURATION
Reconguring a Bendix ESP EC‑80 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 reconguration being carried out
by the technician — the Electronic Control Unit (ECU) will
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 con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 reconguration, it will congure itself to control the
relay to disable the retarding device as needed.
Reconguration Using the Blink Code Switch
With ignition power removed from the Bendix ESP EC‑80
Controller, depress the Blink Code Switch. After the
ignition power is activated, depress and release the switch
seven (7) times to initiate a reconguration event.
Diagnostic Tool
A reconguration event may be initiated using a hand‑held
or PC‑based diagnostic tool to communicate with the ECU
over the SAE J1939 diagnostic link.
6S/5M Conguration
A Bendix ESP EC‑80 Controller will congure for 6S/5M
operation when a reconguration event is initiated, and the
ECU detects that an additional‑axle Pressure Modulating
Valve (PMV) is wired as follows:
PMV Connector ECU Connector
Hold Right Additional Axle Hold
Release Left Additional Axle Release
Common Right Additional Axle Common
DATA STORAGE
Depending on the product type and version, Bendix
®
brand ECUs may store data related to troubleshooting,
diagnostics, service needs, vehicle system operating
status, and vehicle operator inputs. No personally
identifying data (e.g. name, gender or age) is recorded.
Bendix will not access stored ECU data or share it with
others except: with the consent of the vehicle owner; in
response to an ofcial request by law enforcement or
other governmental agency; as part of Bendix’s defense
of litigation; or, as otherwise required by law. Data that
Bendix receives may also be used for research purposes
or made available to others for research purposes, where
a need is shown and the data is not linked to a specic
vehicle or owner.
Bendix brand antilock ECUs are not designed to store
data for purposes of accident reconstruction and Bendix
ACom Diagnostic Software is not intended to retrieve data
for purposes of accident reconstruction. Bendix makes no
representations as to the accuracy of data retrieved and
interpreted from Bendix ECUs for purposes of accident
reconstruction.
