The ECM is one of the most vital components of a modern engine. However, these modules often suffer from visible problems that experienced car owners can directly or indirectly detect. But, a Cummins ECM is not as uncomplicated as spark plugs or other common components of a vehicle’s engine structure. Not many car owners are well-acquainted with these vehicles. So, whenever there’s a minor problem in the ECM, it escalates to damage the entire engine control unit. Conduct these basic and uncomplicated checkups on your vehicle’s ECM –
Physical Examination
A physical examination of a Cummins ECM includes visual and odor tests. The vehicle owner first must visually examine the PINs and make certain that they are standing and undamaged. If these two requirements are met, good. The next step is an odor test. Smell the control unit’s plug. A distinct odor similar to that of burnt plastic is a symptom that there are underlying issues with the module. The safest step would be to further examine the board by unbolting the unit. If you have no clue on how to open the board, avoid carrying out this step. If not, look for signs of corrosion or burns on the board’s inner components. If these signs are there, it’s time for an immediate replacement!
Swap or Substitute Test
The swap test was very common in older vehicles, but due to the complexity of modern engines, it is pretty challenging to carry out on a 21st-century vehicle. In this test, you get to diagnose/troubleshoot your Cummins ECM by a swap test. The process is simple. Look for a replacement ECM unit that has original part numbers. The swap the potentially broken unit with this replacement board. If the vehicle responds to the new module, communicating with it and carrying out all the rest of its functions, it is time to replace your old module. Instead of relying on the substitute model, invest in a new ECM.
Scanning
A simple but effective way of diagnosing your Cummins ECM is to using scanners. You need to have a basic understanding of how these scanners work in order to carry out this process. First, attach the scanning device to the EXM’s OBD-II port. After attachment, you’ll get to view and assess the engine codes sent by the Engine Computer. Look up the meaning of these engine diagnostic codes on the internet. There are several forums on the internet where ECM experts share code that denotes underlying complications, damages, or issues. If you’re having a problem with the code, get an expert to determine what the root of the damage is inside the control unit.
The Need for Self-Assessment
Do you have to suffer from these engine-related issues if you don’t have sufficient knowledge of how to repair or reprogram an ECM? Well, you’ll have to be careful enough not to cause any more damage. Carry out basic steps such as checking the ECMs inputs and outputs. Make sure all the key components – battery, fuel pump, spark plugs, etc. are functioning properly. To read more Click Here
