Software deletion of emission control devices on Volvo FH540 Euro 6
Introduction
Defeating an Adblue system fault on a Volvo FH540 is possible: Software deletion of emission control devices is an operation that consists of modifying the parameters of the engine management system (EMS) and the exhaust gas management module (ACM) in order to delete the emission control devices (Adblue, FAP, EGR) on a Volvo FH540 Euro 6. This operation is generally carried out for reasons of cost, performance and flexibility. Although this operation is legal in some countries, it is important to comply with current environmental and legal standards. In some countries, the removal of anti-pollution devices may be considered an offence and may result in legal sanctions. It is therefore essential to check the regulations in force in your country before carrying out this operation.
Emission control devices are important components in reducing exhaust emissions and protecting the environment. However, they can also cause significant problems and costs if they fail. The DPFS, for example, can become clogged and require costly cleaning or complete replacement. The EGR valve can also cause performance and reliability problems. This is why software deletion can be an interesting solution for reducing maintenance and repair costs associated with emission control devices, without compromising safety or legality. It can also improve engine performance by reducing power losses caused by emission system restrictions.
Adblue system fault on Volvo FH540
The Adblue system is a urea injection system that reduces nitrogen oxide (NOx) emissions in engine exhaust gases. The Adblue system is also present on the Volvo FH540 Euro 6, and can cause problems if it fails. Faults in the Adblue system can lead to disturbances in engine operation, reduced performance, increased fuel consumption and excessive pollutant emissions. Software deletion of emission control devices is a solution for deleting the Adblue system on the Volvo FH540 Euro 6.
Steps in the procedure
Step 1: Identify the tools you need
he tools required to perform software deletion of emission control devices on a Volvo FH540 Euro 6 are flash memory read/write tools for the EMS and ACM ECUs. These tools connect directly to the EMS (bench on the ECU pins) and boot on the ACM.
Step 2: Identify the parameters to be reprogrammed
Once connected to the ECUs, the flash memory read/write tool identifies the EMS and ACM parameters to be reprogrammed in order to remove the anti-pollution devices. These include engine version, software version and required calibration.
Step 3: Development of new parameters
The new parameters required for the software deletion of Adblue, FAP and EGR valves are developed by qualified professionals. The parameters are modified to ensure that the engine operates correctly without the anti-pollution devices.
Step 4: Data flash and fault checking
Once the new parameters have been developed, the data flash (writing of the new program) is performed on the EMS and ACM using the flash memory read/write tool. After the data flash, the manufacturer's tool identifies and reads the EMS and ACM memory to check for any faults and confirm that emission-related faults are no longer present.
No more faults present after system reprogramming.
Volvo FH540 emission control components can be removed
- The urea (Adblue) injection system, comprising Adblue tank, Adblue injection pump, Adblue injectors and Adblue sensors. [the pump can be disconnected].
- The diesel particulate filter (DPF), located in the exhaust system, captures soot particles and burns them later. [the DPF cartridge can be removed].
- The exhaust gas recirculation (EGR) valve, which recycles part of the exhaust gases back into the engine to reduce NOx emissions. [the EGR valve can be blocked with a plate if broken].
Other sensors can also be disconnected if required:
- Differential pressure sensors, which measure the pressure difference across the diesel particulate filter (DPF) to determine when it needs cleaning.
- Exhaust gas temperature sensors, which measure exhaust gas temperature to help regulate the urea (Adblue) injection system.
Software deletion of emission control devices on a Volvo FH540 Euro 6 can have a number of benefits, including reduced maintenance and repair costs associated with emission control devices. Emission control components can be expensive to replace, and their failure can lead to costly repairs. In addition, eliminating emission control devices can also improve engine performance by reducing power losses caused by emission control system restrictions.
