Inactive Diagnostic Trouble Code Mode
The Bendix
®
 ESP
® 
EC‑ 80
 Controller stores past 
Diagnostic Trouble Codes (DTCs) and comments (such 
as configuration changes) in its memory.  This record is 
commonly referred to as “event history.”  When an active 
DTC is cleared, the Electronic Control Unit (ECU) stores it 
in the event history memory as an inactive DTC.
Using blink codes, the technician may review all inactive 
DTCs 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.  See page 26 for the index showing DTCs and 
the troubleshooting guide page to read.
Inactive DTCs, and event history, may be retrieved and 
cleared by using a hand‑held or PC‑based diagnostic tool, 
such as the Bendix
®
 ACom
®
 Diagnostic Software.
Clearing Active DTCs
The ECU will clear active DTCs when the diagnostic Blink 
Code Switch is depressed and released three (3) times.
System Configuration Check Mode
The ABS indicator lamp will display system configuration 
information when the diagnostic Blink Code Switch is 
depressed and released four times.  The lamp will blink 
out  configuration  information  codes  using  the  following 
patterns.  (See Figure 17).
In this mode the ECU tells the technician — by means of a 
series of seven (7) blink codes — the type of ABS system 
that the ECU has been set up to expect.  For example, if 
the fourth blink code is the number two (2), the technician 
knows that a 6S/4M sensor/modulator configuration has 
been set.
Dynamometer Test Mode
The Dynamometer Test Mode is used to disable Bendix
®
  
ESP
®
 & ATC system functions when needed (e.g. when 
performing any vehicle maintenance where the wheels are 
lifted off the ground and moving, including dynamometer 
testing).  Note: For Bendix ESP and ABS EC‑80 
Controllers, this mode will remain engaged even if 
power to the ECU is removed and re‑applied.  
To exit 
the Dynamometer Test Mode, press and release the Blink 
Code Switch three (3) times, or use a hand‑held or PC‑
based diagnostic tool.

FIGURE 17 - SYSTEM CONFIGURATION CHECK
Reconfigure ECU Mode
Controller reconfiguration is carried out by using the 
Reconfigure ECU Mode.  (See page 16.)
Note:  To enter the Reconfiguration Mode, the Blink Code 
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.
Other Methods
Troubleshooting and DTC clearing (as well as reconfigura‑
tion) may also be carried out using hand‑held or PC‑based 
diagnostic tools such as the Bendix
®
 Remote Diagnostic 
Unit (RDU
), Bendix ACom Diagnostic Software, or similar 
tools.
