How does the powertrain control module work?
Powertrain Control Module (PCM) In most cars, the Powertrain Control Module contains the ECM and TCM in one unit. By combining them, the PCM can better regulate their functions together. For example, when the PCM changes gears, it can pull back the throttle to shift smoother.
Which is a symptom of a bad Powertrain Control Module?
The third symptom of a powertrain control module having issues is that the vehicle may not turn on or run properly. A bad PCM can cause the vehicle to not have any engine management control. Without any control, the engine won’t be able to start at all.
How much does it cost to reflash Powertrain Control Module?
Reflashing can also be accomplished using professional grade scan tools, which include the same functionality, plus many other features unrelated to reflashing. These are even more expensive. They can cost from $1000-$5000. Update subscriptions can also be up to $800 per year or more depending on the vendor.
Which is the brain of the engine control system?
Powertrain control modules are often touted as being the brain of the engine control system. We take a lesson in automobile-neurology, as we explore the functions and working of this system. Did You Know? The powertrain control module is just one of the many electronic control units (ECU) used in cars.

What is the name of the engine control module?
The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.
