The Powertrain Control Module abbreviated as PCM is placed in the engine area. PCM is also mentioned as JTEC which is Jeep/Truck Engine Controller. PCM is an electronic control module. The input signals from different switches and sensors are sent to the electronic control module. This module performs all the functions needed in an electronic control system. All the functions which functions in normal car or truck are done manually. In electronic case these functions are done with less amount of coils and wires hence results in substantially low power consumption.
The functionality of PCM in Jeep/Truck
The PCM is also found in the electric partly operatedwindow switchsnakeoil level switch, gearshift indicator, headlight switch and air-fuel mixer switch. In some cars it is also connected to the catalytic converter directly. In some other cars it passes the transmission signal to the driveline. The PCM in some vehicles is also linked to the charging system. In some cars like Ferrari, it is even linked to the brake transmission. The Chevrolet uses a variable transmission with electronic throttle connected to the PCM. Some other cars include Ford a-series, Toyota a-series and rpm. The throttle varies its responsiveness depending on the speed of the engine.
The input signals that are sent to the PCM from different switches and sensors are generally 2 voltage traces. It can be single or double. In some cars a single continuous line is split into two separate wires to give the possibility to analog voltage intermediate. The analog voltage then goes to the second PCM.
Different types of Powertrain Control Modules
There are two types of Powertrain Control Modules existing, Powertrain Control Module and Hybrid Control Module.
Powertrain Control Module with On Board Diagnostic: This is the latest type of Powertrain Control Module. A diagnostic mode is incorporated in the module to detect any problems and the frequency of malfunction. Therefore, if the module finds any problem it can immediately shut down the engine but it does require some additional off board diagnostic hardware.
Powertrain Control Module with Chain-Reulation: This is a relatively new innovation. Chain re-ulation technology is incorporated in modern module, which helps in maintaining the health of the alternator and the engine without the trouble of inspecting the whole system. This module does not include a diagnostic function but the functions it delivers are similar to what a garage would provide for a car under repair.
Powertrain Control Module with Insight: This is an incredible module, which delivers the exact power you need as well as enhancing the overall efficiency of your car. It includes a bunch of sensors, a lot of them are digital and interact with the Powertrain Control Module. This module is mostly used as a support for advanced systems and it certainly offers a lot of functionalities.
Powertrain Control Module with ECC: This is an incredible unit that includes more than a hundred sensors across the vehicles to significantly helps the driver know the fact the his car is running smoothly. This module significantly helps the initiate the driving process and it's a good way to detect any irregularities within your car. You can definitely notice the change in the pick up when you are driving along an over the road. This particular module absorbs the vibration and virtually boom, this is quite useful.
The Powertrain Control Module has made the driving experience comfortable and as comfortable for the driver as it can be, with additional complications, for example the night driving where its quiet as you near the town and all is good. And then as you drive along the straight roads and you need to change gear below 3000 rpm. The Powertrain Control Module helps you out, here is an initial power output of 381 hp at an bang beside the Module.
Therefore, the Powertrain Control Module not only improves the performance of your car but more importantly its functions like Single adopted 90 degree V angle for the Module and the addition of Brake Assist. If you take a look at the advanced functions, the brake assist stresses on application of the progressive braking system, this in turn help's the application of the progressive braking system.
This module offers a good support to the electronic stability of your Jeep. This stability control system is applied to improve the safety aspect of your Jeep. To summarize, the PCM helps perform a lot of functions, for example it is among the essential components needed for the automatic level control. By adding more information and deeperConnections between Powertrain Control Module and the wild card (ECU), a lot of potentials to come out of it have been unlocked.
