The Powertrain Control Module (PCM) on a 2000 Acura TL is typically located in the engine bay, although there are a few models that may have it placed inside the vehicle or even in the trunk. To access the PCM for diagnostic testing or replacement, a technician may need to refer to component location reference material. It’s important to note that the PCM is sometimes referred to as the Engine Control Unit (ECU) on older Acura models, but on newer models, it is called the PCM.
