This reduces gear hunting and wheel spin. TCM functionality has improved over the years, adding input from cruise control, throttle and traction control system. The TCM uses incoming sensor data to determine when the transmission needs to shift. Then, the computer can adjust the ignition and fuel injection timing and the position of the camshafts and throttle. In a modern engine, the ECM will gather sensor data from the intake, exhaust, cooling system, and several internal components to assess the engine’s running condition. Sometimes ECM or ECU are used interchangeably with PCM, so let’s clarify the differences. What’s the Difference Between an ECM, TCM & PCM?īefore we go any further, it’s important to understand the terms that get thrown around in the industry, especially if you’re doing a DIY project or ordering parts online. It’s often referred to as the “brain” of your car because it controls so many functions. The powertrain control module (PCM) is one of the most important computers in your car, usually managing the engine and transmission, depending on the make of your vehicle. They’re now standard on all 2008 and newer cars and light trucks. Manufacturers started phasing in CANs in the early 2000s.

They do this through a system of wires and software protocols called the Controller Area Network, or CAN. Modern vehicles have a set of computers (commonly referred to as modules) that communicate with sensors throughout the car. Cars are upgradeable and customizable, giving the backyard mechanic incredible control over performance. Today, vehicles are really like computers with wheels. They could now control most of the electrical processes of the car, including climate controls, braking systems, and odometer.

By the 1990s, on-board computers became more sophisticated. It wasn’t until the 1980s that microchips and microprocessors became small enough to fit into cars. Circuit boards had specific roles like regulating fuel injection systems. The first computers appeared in cars during the late 1960s and early 1970s. Let’s begin with a brief overview of how car computers evolved, and the role of the powertrain control module in today’s vehicles. We’ll help you understand how reflashing works and what your options are, so you can make the right decision for your car and budget. Whether you’re thinking of reflashing your own powertrain control module or purchasing a replacement, our guide will answer all your questions. Everything You Need to Know About PCM Reflashing
