EC-30

This kit is intended for the replacement of a Bendix

EC-30

™

Electronic Control Unit (ECU). The following are the

necessary steps to replace and conﬁ gure the replacement

ECU.

PREPARATION:

Follow all standard industry safety precautions,

including, but not limited to, those listed at the end of

this document. Park the vehicle on level ground, chock

wheels, and turn off the ignition. Locate the Bendix

Electronic Control Unit (ECU) on the vehicle.

1. Remove the wire harness connectors from the ECU.

2. Remove the four fasteners securing the ECU and retain

for re-installation. Dispose of ECU.

3. Install the replacement ECU and tighten the fasteners to

98 in-lbs.

4. Inspect the wire harnesses and connectors for corrosion,

damage, etc. Replace as necessary. Insert the wire

harness connectors into the replacement ECU and ensure

that the harness is securely attached to the vehicle.

Torque the connector retaining screws to 15-20 in-lbs.

CONFIGURATION PROCESS - PART ONE

Replacement ECUs typically require a self-conﬁ guration

to adjust to the number of wheel speed sensors and/or the

Automatic Traction Control (ATC) conﬁ guration of the vehicle.

To Self-Conﬁ gure:

a. Verify that the following are connected to the EC-30

ECU and are operational:

• All connectors to the ECU.

• J1939 or J1922 communication link to the engine.

• ATC active/indicator lamp.

• ATC enable/disable switch (NOTE: Switch must be

toggled prior to self-conﬁ guration if enabling ATC).

b. Self-Conﬁ guration Procedure

Verify that all ECU, communication, sensor, and ABS

modulator connectors are in place and then turn the ignition

power on. Toggle the ATC enable/disable switch if equipped.

Activate an EC-30

the following actions:

• Hold a magnet on the reset location of the Remote

Diagnostic Unit (RDU) for approximately 20 seconds (until

the LEDs begin to rapidly roll), then remove the magnet.

• Hold a magnet on the reset location of the diagnostic

display for more than 6 seconds, but less than 11 seconds,

then remove the magnet to initiate a self-conﬁ guration.

• Using ACom

in the "configuration window" select the "self-config"

button or select "modify and conﬁ gure the ECU" from the

parameters available in the "conﬁ guration window".

When the self-conﬁ guration process is complete, the EC-30

controller will automatically go through the power-up sequence

and show the new conﬁ guration on its LED diagnostic display.

If the EC-30

speed sensors and ATC, both the ABS and ATC indicator

lamps will extinguish at the end of the power-up sequence.

CONFIGURATION PROCESS - PART TWO

Almost all Bendix replacement ECUs support Power Line

Carrier (PLC). Using ACom

5.9 or higher), conﬁ rm that the ECU installed has this feature.

™

Some older vehicles, however, may not support PLC. In

these cases, it is recommended that the technician turn off

the ECU's support of PLC.
