You may need to learn how to repair your car’s SCR. There are many steps that you can take in order to correct please click the up coming website page issue. The first step is to identify the underlying problem. Then, you can either replace the QLS sensor or the Aftertreatment Control Module. If you have any kind of queries with regards to exactly where and also how to make use of scr system altered or fault detected peterbilt, you can e mail us in the web-site.
Replacing QLS sensor in SCR system
The SCR system will display an engine warning light when a sensor fails. Once the engine stops running for at least an hour, the SCR will enter a 25% de-rate. The vehicle will then slow down to 5 mph. Technicians will need to replace your QLS sensor with a functioning one in order to fix the problem.

Replacing Aftertreatment Control Modules in the SCR system
The Aftertreatment Control Module can be replaced in your SCR system. It will produce a cleaner exhaust stream. The system uses a chemical reducer called DEF, also known as Diesel Exhaust fluid, to reduce harmful nitrogen oxides and make them harmless. The SCR system not only reduces nitrogen oxides but also has a control system that monitors engine temperature and pressure to maintain peak performance.
The Aftertreatment Control Module, or ACM, is responsible for ensuring that the SCR system works efficiently. It controls the NOx levels in the system and determines if the DPF should be cleaned. In some embodiments, an input function is provided by the ACM module to determine if please click the up coming website page DPF must clean to meet emission thresholds. Other embodiments of the ACM module include fewer features and functionality.
