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.
LO = NO
HI = YES

Starts here:

PRESS:
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 ..

PRESS:
LO
- until " ECM " comes up

PRESS:
HI
- until " CLEAR CODES ? " comes up

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

you are done ...

PRESS RESET and you are back to normal

This is a older posting-on the off chance it's still reveiwed, my 1992 Allante has different ABS codes than listed here. I'm looking for the FSM discription for Code 64 on the Bosch III System. Does anyone have this info??
