How to solve adblue issues on CAT 315F excavators, permanently.
Description of symptoms and fault codes
To solve AdBlue problems on CAT 315F excavators: The machine shows signs of impaired performance, such as repetitive power loss during operation. These power losses may be accompanied by error messages displayed on the instrument panel, indicating problems with the AdBlue emission reduction system. Diagnosing the cause of these symptoms is essential to maintain optimum machine performance and avoid potential breakdowns. We recommend checking the following AdBlue system error codes
Overall description of defects :
E954: Low Aftertreatment DEF Tank: Lack of emission control fluid in the tank interrupts regeneration of the diesel particulate filter (DPF) and reduces the efficiency of the SCR system.
E1389: After treatment SCR Operator inducement : SCR control system fault causes reduced system performance. SCR (Selective Catalytic Reduction) is a system used to reduce nitrogen oxide (NOx) emissions in diesel engines. The SCR operator inducement refers to an error message indicating that there is a problem with the SCR control system. It is often linked to problems with pressure, temperature, AdBlue flow rate, or defective components in the SCR system. It can also be linked to a lack of emission control fluid in the tank.
E1370: Aftertreatmet Def dosing Unit Loss of prime: The problem with the aftertreatmet liquid dosing unit is reducing the efficiency of the SCR system.
E931 and E930: Low/High Aftertreatment Def Pressure: The problem of emission control fluid pressure leads to reduced SCR system efficiency.
E1309: Low Aftertreatment SCR Catalyst conversion Efficiency (ET) None: The SCR system’s catalytic conversion efficiency problem results in a loss of overall machine performance.
Consequences for the current site and emergency solution
The faults mentioned in the fault codes can have a significant impact on machine performance. For example, recurrent power loss, interrupted diesel particulate filter (DPF) regeneration and SCR system pressure and temperature problems can all cause delays and reduced productivity on the job site. As a result, these faults can cause machine breakdowns and require costly repairs, resulting in lost money for the company. In addition, it is important to diagnose and resolve these problems quickly to minimize the impact on machine performance and the costs associated with maintenance and repairs. Definitive elimination of defects has proved to be the ultimate and most effective solution for avoiding late penalties.
The ultimate solution: eliminating fault and adblue injection systems
AdBlue settings can be deactivated by software to solve adblue issue on CAT 315F using a program specially developed for this purpose. This type of program deactivates AdBlue-related functions such as the injection of emission-reducing fluid and the regeneration of the diesel particulate filter (DPF).
To do this, it is necessary to access the vehicle’s ECU (Electronic Control Unit) parameters and modify the configuration settings. This can be done using a diagnostic tool specially designed to access ECU parameters. This maintains the machine’s performance without the additional cost of using AdBlue. Savings can also be made on maintenance and repair costs by avoiding problems with the AdBlue system.
It is important to check that flashing is carried out by competent professionals to avoid material damage or machine performance problems. If flashing is carried out correctly, it can help keep the machine running smoothly on site, and avoid delay penalties.
