How Software Can Make Your Grand Cherokee's PCM Better

By Granderson Elliot


The ECU is the brain of the car. It is important in the performance of the car and its fuel system. It determines the amount of fuel used up by the engine of a car, like a Cherokee, in consideration to the throttle position, amount of air in the engine, and the transmission gear, among others. Therefore, your Jeep Grand Cherokee ECM is the one that controls the whole performance of the car.

Without the ECU or sometimes referred to as a computer or an ECU, your Jeep Grand Cherokee will not run well. Although manufacturers make these computers to last for a long time, you can still experience occasional troubles.

The components of the car will not function well as the computer cannot receive the necessary information because of the electronic troubles. If this is the case, the computer of the Dodge Caravan will not receive information regarding the fuel needs of the engine. As a result, maintaining the accurate speed of the car is not possible. Worse, there is also a chance that your car will not start or even completely not function anymore.

Another important component of the car that works with the computer is the airflow sensor. Actually, the ECU can release the right amount of fuel to its engine if the sensor is able to give the exact information on the amount of air that flows inside the engine.

Thus, you cannot expect the car to run smoothly if the airflow sensor is broken because it is highly possible that the ECU will provide the wrong amount of fuel to the engine.

Because of such problem, you can end up spending a lot of money on gas. Usually, when a car breaks down, the first thing that car owners check is the ECM and in most cases, they are correct. However, you must still check the other parts of the Dodge Grand Caravan ECU, in case you purchase them in the internet.

At times, the reason why a ECM or computer malfunctions is that the fuse blows up. A fuse is very important in protecting the electronic components of a car from any power surges that may cause damage. Although most houses nowadays use circuit breakers, the fuse found in cars look like the ones used at home.

Thus, if your car does not work, the very first thing that you should check out is the fuse. However, if you do not know where to find the car's fuse, maybe you can take a look at the cover of the fuse box. But if you still cannot find it there, better look for the diagram in your Grand Caravan operator manual.

Aside from the factors mentioned above, the software of the ECM that makes it run can also be the cause of the problem. All programs can be corrupt, regardless of the use or application. The software of the ECU is not an exemption. Therefore, you can return the ECU to the dealer as they can determine the problem as well as find a solution to it.
