Erasing ABS Codes from
Computer Memory:
Bosch 2U (Version B)
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) Plug 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).
