Bendix Dci Diagnostic Tool - BENDIX EC-30 ABS-ATC CONTROLLER Manual

BENDIX DCI DIAGNOSTIC TOOL

The Bendix Diagnostic Communication Interface (DCI) is a
hand held diagnostic tool that was designed for use with the
® ™
Bendix EC-17 controller system and can also be used as
a stand alone diagnostic tool for the EC-30
figure 10 for illustration. The Bendix DCI has the same 10
diagnostic LEDs as the EC-30
on the DCI duplicates the function of the magnetic reset on
the EC-30 ™ controller. There are also two DCI status
indicators to indicate power and active communication to
the DCI.
To perform diagnostics using the Bendix DCI, plug the DCI
into the vehicle's J1587 diagnostic link connector. This
connector is generally located on the lower, driver-side portion
of the vehicle dash or under the dash panel. See figure 11
for connector location.
Note: The DCI is not RP-1210 compliant and can not be
used as the communication link to any diagnostic software
intended for use with the EC-30
compliant communication link from the computer to the
vehicle diagnostic connector will be needed.
For further information on the Bendix DCI, or RP-1210
compliant tools, contact Bendix or refer to your local
authorized Bendix dealer.

Reading a Fault with DCI
When a fault is detected, the DCI identifies the faulted
component with the diagnostic LEDs. When a wheel speed
sensor fault, or an ABS modulator fault, is detected, the
SEN or MOD LEDs will be accompanied by two location
LEDs. An example is FRT-RHT-SEN. When these three
LEDs are on, this is an indication of a fault on the front
axle(FRT), right side(RHT), wheel speed sensor(SEN). For
a complete explanation of faults displayed by the DCI LEDs,
see section F, Troubleshooting.
The DCI will only indicate active system faults. When a
fault self-heals or is manually reset, the fault code remains
in fault history. Fault history can be retrieved by using blink
code diagnostics or a capable diagnostic tool.
If faults occur on multiple components, the DCI will display
one fault at a time. When the first fault is fixed and the
EC-30 ™ controller is reset, the next fault will be displayed
on the DCI.
A fault displayed on the DCI will always be accompanied by
the illumination of the ABS warning lamp and/or the ATC
active/warning lamp.
Fault Reset with DCI
After the fault is corrected, the active fault code and LEDs
can be reset by briefly pressing the reset button on the DCI.
All of the DCI diagnostic LEDs will be on while the reset
button is pressed. When the reset button is released, only
the green VLT diagnostic LED should be on. If red LEDs
remain on, active faults are still present in the system.
The EC-30 ™ controller self-configuration will occur when the
reset button is pressed for greater than 20 seconds.
