Troubleshooting Bendix ESP Stability System

DIAGNOSTIC MODES
In order to communicate with the ECU, the controller has several modes that the technician can
select, allowing information to be retrieved, or other ECU functions to be accessed.
To enter the various diagnostic modes:
No. of Times
to Press the
Blink Code
Switch

Active diagnostic trouble code retrieval

2

Inactive diagnostic trouble code retrieval

3

Clear active diagnostic trouble codes

4

System configuration check

Active Diagnostic Trouble Code Mode
For troubleshooting, typically the Active and Inactive Diagnostic Trouble Retrieval Modes are
used. The technician presses the blink code switch once and the ABS indicator lamp flashes
a first group of two codes, and if there are more trouble codes recorded, this is followed by a
second set of codes, etc. (See this page for a brief directory of these codes.)
Clearing Diagnostic Trouble Codes
To clear active diagnostic trouble codes (as problems are fixed), simply clear (or “self-heal”) by
removing and re-applying ignition power. The only exception is for wheel speed sensor trouble
codes, which clear when power is removed, re-applied, and the ECU detects valid wheel speed
from all wheel speed sensors. Alternately, codes may be cleared by pressing the diagnostic
blink code switch 3 times (to enter the Clear Active Diagnostic Trouble Code Mode) or by using
a hand-held or PC-based diagnostic tool. Hand-held or PC-based diagnostic tools are able to
clear wheel speed sensor trouble codes without the vehicle being driven.

Clearing Active Diagnostic Trouble Codes
The ECU will clear active trouble codes when the diagnostic blink code switch is depressed
and released three times.

Visit www.bendix.com or www.foundationbrakes.com for Service Data
Sheets and other literature such as the following:

* To enter the Reconfiguration Mode, the switch must be held in
before the application of ignition power. Once the power is supplied,
the switch is released and then pressed seven times.

Inactive Diagnostic Trouble Code Mode
The ECU stores past trouble codes and comments (such as configuration changes) in its memory.
This record is commonly referred to as “event history.” When an active trouble code is cleared,
the ECU stores it in the event history memory as an inactive trouble code.
Using blink codes, the technician may review all inactive trouble codes stored on the ECU. The
ABS indicator lamp will display inactive diagnostic blink codes when the diagnostic blink code
switch is depressed and released two times.
Inactive trouble codes, and event history, may be retrieved and cleared by using a hand-held or
PC-based diagnostic tool, such as the Bendix® ACom™ Diagnostics software.

Troubleshooting: PC-based Troubleshooting, Blink Codes and Diagnostic Tools & Modes
The information presented here is condensed from the troubleshooting section of the Bendix® EC-60™ Advanced ABS Controller Service Data Sheet, SD-13-4869 available for download on www.bendix.com. Whenever possible, use a PC-based diagnostic tool, such as the Bendix®
ACom™ Software (free download from www.bendix.com) or hand-held Bendix® Remote Diagnostic Unit (RDU). The Bendix® ACom™ Software uses on-screen troubleshooting steps to help correct any DTCs. The Bendix® ACom™ Software (BW2329) may also be ordered on CD from the
Literature Center at www.bendix.com.

BLINK CODES
Blink codes allow a technician to troubleshoot ABS problems in situations where a hand-held
or PC-based diagnostic tool is not available. Instead, information about the ABS system is
communicated by the ECU, using the ABS indicator lamp to display sequences of blinks.
Note: The ECU will not enter the diagnostic blink code mode if the wheel speed sensors show
that the vehicle is in motion. If the ECU is in the diagnostic blink code mode and then detects
vehicle motion, it will exit the blink code mode.
In addition, by operating the blink code switch as described below, one of several diagnostic
modes can be entered. See Diagnostic Modes section below.
Blink Code Switch Activation
When activating the blink code switch:

ECU DIAGNOSTICS
The EC-60™ controller contains self-testing diagnostic circuitry that continuously checks for the
normal operation of internal components and circuitry, as well as external ABS components
and wiring.
Active Diagnostic Trouble Codes (DTCs)
When an erroneous system condition is detected, the EC-60™ controller:
1. Illuminates the appropriate indicator lamp(s) and disengages part or all of the ABS, ATC
and ESP functions. (See Service Data Sheet.)
2. Places the appropriate trouble code information in the ECU memory.
3. Communicates the appropriate trouble code information over the serial communications
diagnostic link as required. Hand-held or PC-based diagnostic tools attach to the vehicle
diagnostic connector, typically located on or under the dash.
When using our PC-based Bendix® ACom™ Software, follow the on-screen troubleshooting
steps to correct any DTCs. A hand-held tool such as the Bendix Remote Diagnostic Unit (RDU)
provides direct access to the DTCs without the need to use blink codes.

1. Wait at least two seconds after “ignition on.” (Except when entering Reconfiguration Mode
- see Service Data sheet.)
2. For the ECU to recognize that the switch is activated “on,” the technician must press for at
least 0.1 seconds, but less than 5 seconds. (If the switch is held for more than 5 seconds,
the ECU will register a malfunctioning switch.)
3. Pauses between pressing the switch when a sequence is required, (e.g. when changing
mode) must not be longer than 2 seconds.
4. After a pause of 3.5 seconds, the ECU will begin responding with output information blinks.

Blink Code Timing
The ECU responds with a sequence of blink codes. The overall blink code response from the
ECU is called a “message.” Each message includes, depending on the mode selected by the
technician, a sequence of one or more groups of blinks. Simply record the number of blinks for
each sequence and then use the brief troubleshooting index shown here, or full troubleshooting
information in the Service Data sheet, for active or inactive trouble codes.
NOTE:
1. Sequences of blinks illuminate the ABS indicator lamp for half a second, with half-second
pauses between them.
2. Pauses between blink code digits are 1.5 seconds.
3. Pauses between blink code messages are 2.5 seconds.
4. The lamp remains on for 5 seconds at the end of the messages.
Once the ABS indicator lamp begins displaying a sequence of codes, it continues until all blink
code messages have been displayed and then returns to the normal operating mode. During
this time, the ECU will ignore any additional blink code switch activation.
All trouble codes, with the exception of voltage and J1939 trouble codes, will remain in an active
state for the remainder of the power cycle.
Voltage trouble codes will clear automatically when the voltage returns within the required limits.
All ABS functions will be re-engaged.
J1939 trouble codes will clear automatically when communications are re-established.
