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.

before the application of ignition power. Once the power is supplied,
the switch is released and then pressed seven times.
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 fl ashes
a fi rst 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 fi xed), 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.
To clear active diagnostic trouble codes (as problems are fi xed), 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.
Inactive Diagnostic Trouble Code Mode
The ECU stores past trouble codes and comments (such as confi guration 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
