replace the ecm
you can't fix an ecm, you have to replace it.

i need to replace the ecm on a 1993 olds cutlass supreme,can i replace it with another ecm from another olds cutlass?
No. Too many differences between those years.
It is not very often that an ECM needs to be replaced. Generally they can be reprogrammed. Be sure of what and why you are doing what you are about to do. Guessing is very costly.
the quad driver module is a component of the ECM. you must replace ECM.
Pull your glove box. Located on right. Disconnect 2 wiring harness's then unit will slide out with a little "wiggling". New ecm will need you to pull the prim , rubber stops and clips from your old ecm and replace on new ecm. Most parts stores will let you use tools at the counter to replace right there.

The ECM is located behind the glovebox on a 1991 Cutlass Ciera. Pull the glove box out to see it. Once located remove the mounting hardware and unplug it from the car. Replace the unit.
It's programmed into the engine ECM. You need to either replace the ECM, or have the existing one reflashed with new parameters.
