Powertrain control module (PCM) – Sometimes the functions of the engine control unit and transmission control module (TCM) are combined into a single unit called the Powertrain Control Module. Seat control unit; Speed control unit (SCU) Telematic control unit (TCU) Transmission control module (TCM) Brake control module (BCM; ABS or ESC)
Simple fault code readers/reset tools are mostly aimed at the consumer level. Professional hand-held scan tools may possess more advanced functions Access more advanced diagnostics; Set manufacturer- or vehicle-specific ECU parameters; Access and control other control units, such as air bag or ABS
The Sensotronic Brake Control (SBC) system allows for precise control of brake pressure at each wheel, enabling the use of stability control methods such as Anti-lock Braking System (ABS) and Electronic Stability Program (ESP). On some vehicles, the system incorporates features designed to enhance driver convenience, including:
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
In intermediate level ESC systems, ABS will be disabled, or the computer will actively lock the wheels when brakes are applied. In these systems, or in vehicles without ABS, the performance in emergency braking in slippery conditions is greatly improved as grip state can change extremely rapidly and unpredictably off-road when coupled with inertia.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine.

An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the ...
