Reconguring Bendix

EC-80

™

Controllers

SYSTEM RECONFIGURATION

The Bendix

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. When replacing an ECU, be sure to use an

equivalent Bendix

replacement part number so that the

standard default settings are provided.

Depending on the version, the customizable features include

ABS control settings, engine module communication, etc.

Many of these settings can be recongured using a hand-

held diagnostic tool or PC‑based software, such as the

Bendix

ACom

Diagnostics program.

ECU RECONFIGURATION

Reconguring Bendix EC-80 ABS ECUs

Reconguring a Bendix

EC‑80 ABS 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 reconguration process, and independently

from any recon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 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guring Bendix

EC-80 ATC ECUs

As with non‑ATC ECUs, the Bendix

EC‑80 ATC ECU also

carries out — independently from any recon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, Bendix

EC‑80 ATC controllers will determine the number of wheel

speed sensors and PMVs installed and congure itself

accordingly.

6S/5M Conguration

Bendix

EC-80 ATC controllers will congure for 6S/5M

operation when a recon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 Schematic (page 37) for details.

Reconguration Using the Blink Code Switch

The reconguration procedure is the same for ATC and

non‑ATC ECUs. With ignition power removed from the

Bendix

EC‑80 controller, depress the blink code switch.

After the ignition power is activated, depress and release

the switch seven times to initiate a reconguration.

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.
