Clear the code from the ECU

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 

Good Luck and Hope this helps

89 Cadillac sedan deville when car is on the service engine light comes on and have to disconnect the battery to restart the computer

Disconnecting the battery will neither clear the code, nor stop the light from coming on. Press OFF and WARM together on the a/c panel to read codes. Once repair is made, codes can be cleared by pressing and holding the OFF and HI buttons

How do i shut off the service soon light on my cadillac

You will have to take it to a repair shop that has an OBD I scan tool to clear the code(s), you maybe able to clear the code(s) by disconnecting the battery for about 10 - 15 min. And see if that works (depending on what type of fault code was stored to set the light). Hope this helps.
