Erasing ABS Codes from Computer
Memory: Bosch 2U (Version C)
Erase codes from memory whenever
you complete a repair or to see if a
problem will occur again. Note: The
computer will automatically erase
codes after several restarts (typically
100) if the problem does not return.
Proceed as follows:
1) Turn the ignition
switch to the ON
position. The anti-
lock lamp should
turn OFF after 3
to 4 seconds. If it
does not, a current failure still exists
which must be corrected before its
corresponding trouble code will
clear.
2) Install the
Code Scanner
(make sure
the TEST
switch is in
the ABS position)
into the test
connector until the
anti-lock lamp
turns ON. Remove the Code
Scanner. The anti-lock lamp will turn
OFF.
3) Without turning the ignition switch
OFF, repeat
the sequence
outlined in
Step 2, 2 more
times.
4) All diagnostic trouble codes should
now be cleared. Confirm this by
turning the ignition switch OFF,
installing the Code Scanner, and
turning the ignition switch back to
the ON position (do not start the
engine). Code 12, the “diagnostic
system operational” code should be
the only code displayed.
5) Turn the ignition
switch OFF.
Remove the
Code Scanner,
and reinstall the
test connector
cover (if used
on vehicle). OF
