You can find the 2001 Buick Century Oddie control module on the passenger side firewall. The body control module will be near the bottom of the firewall.
The coils are mounted to it.

Inside the car, passenger side, under the glove compartment.

You will find the ICM directly below the coils. Just remove the coils and you will be able to remove it. This is on a 1990 Buick Century V6 3300 engine. If you have a different engine I cannot confirm the location.
If you are referring to resetting the Check Engine Light then you will need to have someone with a scanner to do it. If you are referring to reprogramming the Engine Control Module then the dealer will do it.
Yes the ecm( engine control module)/ pcm( powertrain control module) are the same thing. Different manufacturers use different acronyms, ECU (engine control unit) is another often used.
I just bought one for $86.00 from an Autozone in Wisconsin. Compare that to your local tax rates and you have your answer. However, have a auto parts store check your old one first it may not be bad.
