What is the PCM on a Dodge Durango?
The powertrain control module (PCM) in your Dodge Durango is located on the right (passenger side) of the engine compartment. It is the circuit board computer for the SUV designed to withstand extreme temperatures. The components in the engine, transmission, drivetrain and other areas send information to the PCM.

What’s the difference between an ECM and a PCM?
The terms “ECM” and “PCM” are used interchangeably when referring to engine electronics, but there is a difference between both units. An “ECM” is an Engine Control Module, sometimes referred to as an “ECU,” or Engine Control Unit. This computer takes incoming sensor data to alter the function of electronic systems.
What’s the difference between a TCU and an ECM?
Before we get into the PCM, let’s talk about the Transmission Control Module (TCM) since it works in tandem with the ECM. It’s sometimes referred to as a transmission control unit (TCU). This device uses incoming sensor data to determine when the transmission needs to shift.
Can a bad ECM cause a bad PCM?
A bad battery, fuel filter, bad injectors or burnt ignition coils can be the culprit rather than damage to the PCM or ECM. Once the PCM or ECM is damaged, it must be replaced.

Why does a car have an ECM system?
For cars with a manual transmission, they only had an ECM because there was no need for a computer to operate the transmission functions. – Electronic Control Unit – The term electronic control unit (ECU) is often used as a generic term for any built-in system that controls multiple electrical features in a car.
