ecm location

right side under the glove box and to the right. Here are the diagrams on what it looks like and the location under the dash on the right side. Check out the images (Below). Please let us know what happens.

its in the passenger compartment, behind the glove box

i had no idea they change its location mitchell on demand and all data both agree with me its under the right side of the dash mitchell had no clear picture so this is from all-data let me know if i need to update my books !

sorry its under the air filter, its to big to fit there. Alldata is wrong?

V8 front wheel drive automatic.

I have heard it is behind the glove box, but I want to be sure. There were two modules I could see there but the part numbers corresponded to the airbag module and climate control module.

There were wires with warnings about not probing due to the airbag module being connected, so I did not want to look any further.

Is the PCM the other silver box up and behind the airbag module? If so, is it okay to disconnect those wire harnesses in the way? It will not engage the airbag.

Any tips on what size socket is needed and where all the bolts are keeping the PCM attached?

I need to remove the PCM to install a memory chip adapter so I can do some real-time tuning with a Moates emulator.

Thanks!

The PCM is behind the glove box, up in the corner. Three different size connectors, I think just a 10mm nut on a stud and bracket will allow it to be removed.

1985 Cadallic sedan deville 401 engine. Where is the location of the engine control module? The box I think it is has numbers 861546 and 41247489.

Thanks.

You have a 4.1 engine, not a 401.
It's located behind RH Side Of I/P, Near Shroud

the ecm is under the r/side dash under the lower panel on the firewall.why are you replacing it????

Have checked dery thing else, the engine will run with key in start. Release start circuit the engine quits. Open to any suggestions for I think this control is a bear to get out.

I'd say you are probably wrong on both counts. I doubt the controller has anything to do with that symptom and it isn't really that hard to change. I'd take a close look at the ignition switch.

youll need to remove the ingition switch on the steering column.operate the switch with a screwdriver.start the car and testdrive.no ecm replacment
