Default RESET Diagnostic CODES, Cadillac Allante models

How does one RESET the codes on an Allante?
I guess not everyone can read " GM GREEK" ?

Here you go ..

For the purposes of the D.I.C.

Starts here:

OFF & WARM (red button) together
- the D.I.C. will light up the instrument cluster like a Christmas tree
- the D.I.C. will start diagnostics, as soon as it starts displaying ..

- until " ECM " comes up

- until " CLEAR CODES ? " comes up

- press only once
- response will be in a few seconds: CODES CLEARED

you are done ...

PRESS RESET and you are back to normal

Translation complements of yours truly @


***** print this out and place it in the Glove box *****

Diagnostic Ssytem Trees coming soon ..
