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. See page 20 for the index showing trouble codes
and the troubleshooting guide page to read for help.
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.
Clearing Active Diagnostic Trouble Codes
The ECU will clear active trouble codes when the diagnostic
blink code switch is depressed and released three 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 Chart 3). In this mode the ECU tells the
technician, by means of a series of seven blink codes, the
type of ABS system that the ECU has been set up to expect.
For example, if the fourth blink code is a two, the technician
knows that a 6S/4M sensor/modulator configuration has
been set.
Dynamometer Test Mode
The Dynamometer Test Mode is used to disable ESP &
ATC when needed (e.g. when performing any vehicle
maintenance where the wheels are lifted off the ground
and moving, including dyno testing). For Advanced ABS
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 times, or use a hand-held or
PC-based diagnostic tool.
Reconfigure ECU Mode
Controller reconfiguration is carried out by using the
Reconfigure ECU Mode. (See page 11.)
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.
