Diagnosing Scr System Fault

You must have a bad NOX sensor if the emission system lamp is on. This indicates potential issues with the SCR system. Checking the fuel tank is another step in diagnosing SCR faults, as low DEF levels can trigger the warning light. SCR, or Selective Catalytic Reduction, is a technology that converts harmful NOx into nitrogen and water using DEF. An SCR warning light means the system may not function properly due to low AdBlue levels or system faults. Common causes of SCR faults include faulty sensors, wiring issues, or DEF quality problems. Deal with electrical and wiring issues first, then check sensors and system components for faults. Modern Kenworth trucks are known for SCR system problems, indicating potential issues with the manufacturer’s technology.


Fixing Scr System Fault

Common solutions for SCR system faults:

  • In case of an SCR fault, it can be due to a faulty NOx sensor, DEF quality sensor, or wiring issue to SCR sensors/components.
  • If the AdBlue fluid runs out, the SCR system will not operate normally, leading to power reduction messages and warning lights.
  • Some solutions involve resetting the SCR system software and checking the fuel tank and system components for issues.
  • Electrical and wiring issues, including battery connections and fuse checks, might help in resolving SCR system faults.

Driving With An Scr System Fault

In case of an SCR system fault, it is not recommended to drive the vehicle as it can impact engine performance and emissions control. Continuing to drive with an SCR system fault can cause further damage and lead to costly repairs.

Frequently Asked Questions Of How To Fix Scr System Fault Kenworth

What Does Scr Mean On A Kenworth?

SCR on a Kenworth stands for Selective Catalytic Reduction, an exhaust aftertreatment technology that converts harmful nitrogen oxides (NOx) into harmless nitrogen and water using a reductant called Diesel Exhaust Fluid (DEF). It helps to reduce emissions and comply with environmental regulations.

How Do I Reset My Scr System?

To reset your SCR system, access the vehicle settings menu and locate the SCR reset option. Confirm the reset to clear any faults.

What Causes Scr System Fault?

An SCR system fault can be caused by a faulty NOx sensor, DEF quality sensor, or wiring issue to SCR sensors/components.

What Does Scr Warning Light Mean?

The SCR warning light indicates a fault in the Selective Catalytic Reduction (SCR) system, which helps reduce NOx emissions. When the AdBlue ® fluid runs out, the light turns on, affecting the system’s operation. This may be due to a faulty sensor or wiring issue.

Resetting the SCR system software may help resolve the fault.

Conclusion

If you’re facing a SCR system fault on your Kenworth, understanding the issue is crucial. Addressing possible causes like faulty sensors or wiring can help resolve the problem efficiently. Stay informed and take necessary steps to ensure your vehicle’s SCR system operates smoothly.

Trust in proper diagnosis and maintenance procedures for optimal performance.
