Engine diagnosis is not an easy task to do. However, proper diagnosis is important for maintaining the longevity and performance of CAT (Caterpillar) engines. CAT engines are known for their efficiency and reliability in the machinist industry. They are used in many applications, from power generation to the construction of different machinery. Moreover, like many other engines, these engines might experience many diagnosis issues that can be resolved with clearance codes.
But how can we read those codes? That’s the practical approach that you need to know, and by choosing the right coded machinist, you can operate CAT engines properly. All of these engine codes are stored in ECM (Engine Control Module), which can be used to upgrade the machine’s performance and health. So, let’s learn about reading and cleaning different codes in the CAT engine.
Common Engine Codes in CAT Engines
Engine codes are also known as diagnostic trouble codes and are stored in the ECM of their engines. While working in CAT engines, ECM generates these alphanumeric codes when it detects some abnormal conditions or malfunctions issues in the engine system. These codes are then stored in the computer memory and easily retrieved using diagnostic tools. Each of the codes is used to resolve specific issues such as fuel system issues, sensor malfunctions, engine system faults, etc.
Before you learn how to clean and read engine codes, look at the codes you must know before operating CAT engines. These are:
P Codes:
It is a Power train code that shows issues related to the engine, transmission, or other power train components.
B Codes:
This code usually relates to the problems running in CAT engine body systems like airbag systems, door modules, or lighting.
C Codes:
The code is typically related to the CAT chassis systems, such as suspension or steering.
U Codes:
U codes combine with a network or wide code dealing with normal communication issues between vehicle modules.
Tools You Need for Reading CAT Engine Codes
After knowing the list of codes you need to know while operating the CAT engine, you must also know about the tools. All of these tools help you read and clear engine-coded CAT codes that you need for specific issue diagnoses.
CAT ET Diagnostic Software:
ET diagnosis software is a tool that is specially made for CAT engines. Also, it allows the technicians to read DTCs, find out engine parameters, and perform different diagnosis tests.
CAT Communication Adapter:
The hardware adapter can easily connect with the CAT engines. Also, the technicians can connect it directly to the tablet or laptop to run ET software.
OBD-II Scanner:
It is an optional diagnosis tool that technicians use. It is useful for finding differences with OBD-II protocols. This is a generic scanner that helps read and clear the CAT codes.
Step-by-Step Guide to Reading Engine Codes
Once you know about the codes and the tools required to diagnose engine issues you must need to have a look at the reading guide. Follow the step-by-step guide to read these engine codes.
- Firstly, Connect the Diagnostic Tools
Firstly, you need to attach the CAT communication adapter to the engine port. Once you connect it, you can easily examine the issue using the adapter. Also, the port is usually located near the CAT engine which controls different modules of the engine.
After that connect the adapter with the tablet or tablet. Plug the adapter directly into the laptop where you install CAT ET diagnostic software. In this way, you can diagnose the issue through software.
- Launch the CAT ET Diagnostic Software
Once you connect the diagnostic tool with the CAT software you need to open the software and start operating CAT ET software directly on your system. Pick the correct engine model you are using with its configuration steps from the software menu. The step allows you to communicate directly with the ECM through using different codes.
- Read the Diagnostic Codes
After you successfully launch the CAT ET diagnostic software, you can access the code menu. Drag the list of codes and use the proper code to diagnose the issues you are facing. You can choose the option Fault Codes to choose the code and resolve particular issues. You can read the effects and functions of that code on your tablet before configuring it directly on CAT engines.
Brief Guide to Clear CAT Engine Codes
Once you know about the list of codes, their application, and diagnostic tools and how to read them properly, you must know how to clean them properly. It allows you to prepare the CAT engine properly. After diagnosing and addressing the issues, you need to know how to clear them properly. It is not easy to reset the functions after you verify the issue. Let us help you to assist with the guide related to clearing CAT engine codes using CAT ET diagnostic software.
- First, Fix the Highlight Issue: Once you identify the issue, you are allowed to clear the codes. Cleaning codes without addressing and fixing the issue may result in more problematic responses.
- Select Clear Codes or Reset Option: While using ER diagnosis software, you need to know how to clear the code or choose the reset option. Simply select the “Clear Codes” or “Reset” option to clear the codes with the ET diagnostic software.
- Lastly, Verify the Reset Option: After clearing the CAT engine codes, restart the engine. This way you can recheck for any new or recurring codes. The step is important to figure out the problem and make sure that it has been fully resolved and your engine is functioning correctly.
Conclusion:
Reading and cleaning CAT engine codes is an important part of a technician’s job. However, by following the step-by-step guide, you can maintain engine reliability and performance as well. With the help of CAT ET diagnostic software, you can easily diagnose the issue and run the tasks smoothly. You can consult with the technicians or perform regular maintenance to ensure your CAT engine is running properly. Follow our above guide to learn how to properly read and clear the CAT engine’s cost!
