how to fix scr system fault volvo loader

Volvo loader is one of the machines commonly used in the construction industry. It is known for its reliability and efficiency. Despite its exceptional performance, it may develop some faults that require immediate attention to avoid severe damages. One of the most common faults associated with a Volvo loader is the SCR system fault. In this article, we will elaborate on how to fix SCR system fault Volvo loader.

What is an SCR system fault?

The SCR (Selective Catalytic Reduction) system is a technology used in diesel engines to reduce harmful emissions such as nitrogen oxides (NOx). Its main components include DEF (Diesel Exhaust Fluid), a catalytic converter, and a control module. An SCR system fault occurs when there is a malfunction in any of these components. The most common causes of an SCR system fault include low DEF levels, a faulty DEF injector, or a damaged catalytic converter.

How to diagnose an SCR system fault

Before fixing an SCR system fault, it is essential to diagnose the problem accurately. With the help of a diagnostic scanner, you can easily retrieve fault codes and identify the component causing the problem. The first step in diagnosing an SCR system fault is to connect the scanner to the loader's OBD port. The scanner will then communicate with the control module and display any fault codes. It is advisable to consult the user manual or seek professional assistance if you are uncertain about the fault codes' interpretation.

How to fix an SCR system fault

Once you have identified the component causing the SCR system fault, it's time to fix the problem. If the fault is due to low DEF levels, the solution would be to refill the DEF tank. However, if the DEF injector is faulty, it needs to be replaced. The catalytic converter is another critical component that can cause an SCR system fault. If damaged, it needs to be replaced as well. It is advisable to buy genuine and high-quality replacement parts to ensure optimal performance.

Prevention measures

Prevention is always better than cure. To avoid an SCR system fault, you should adhere to the manufacturer's recommended maintenance schedule. Regularly checking the DEF levels and refilling them when low can also prevent an SCR system fault. Additionally, avoid using contaminated or cheap DEF as it can damage the injector and catalytic converter, causing an SCR system fault.

Conclusion

In conclusion, an SCR system fault is a common problem associated with Volvo load. Proper diagnosis, timely repair, and maintenance are crucial in preventing severe damages. Remember to use high-quality and genuine replacement parts to ensure optimal performance. Adhering to the manufacturer's recommended maintenance schedule, regularly checking the DEF level, and using proper DEF can prevent an SCR system fault.
