Solving an adblue fault on DAF XF105.460
How to permanently remove adblue fault on DAF XF105.460
The AdBlue fault on a DAF XF105.460 can have several causes. The fault here is the P2100 and the U0113 reduce engine performance. First let’s see what these faults correspond to, then we will explain how to virtualize the SCR system.
The P2100 fault indicates that the engine is in “derate” mode due to a fault in the AdBlue system. The “derate” mode consists of limiting engine performance in order to reduce pollutant emissions. This can result in a reduction in the power and maximum speed of the vehicle.
The probable cause comes from fault U0113:
Error message U0113 indicates that there is a problem with the frequency of messages sent by the AdBlue system to the vehicle’s communication network (CAN, Controller Area Network). Depending on the message, the message frequency can be either too high or too low. This type of fault can have several causes. It could be a problem with the AdBlue system itself, such as a faulty sensor or a damaged electrical circuit. It could also be a problem with the vehicle’s communication network, such as a damaged cable or a faulty interface.
Following the messages and the number of parts already changed, the solution was to emulate the system
An AdBlue emulator is a device that is installed on a vehicle equipped with the SCR system using AdBlue, with the aim of bypassing or deactivating the system. Installing an emulator on DAF 105.460 will allow the truck to regain its torque and power and thus allow it to regain its nominal efficiency. The adblue emulator is mounted on the CANbus network of the truck.
In general, this is how an AdBlue emulator can be mounted on a vehicle:
Locate the vehicle’s OBD II (On-Board Diagnostic) diagnostic connector. It is usually located under the dashboard, near the steering column.
Plug the emulator into the OBD II connector, making sure that the colors of the wires match those of the connector pins.
Connect the emulator to the vehicle’s 12/24V power supply, using either the cigarette lighter socket, or by connecting the emulator directly to the vehicle battery.
Connect the emulator to the vehicle’s CAN communication system using the CAN H and CAN L wires. These wires are usually found in the OBD II connector or in an electronic box of the vehicle under the grille.
What data is virtualized by our box?
Our AdBlue emulator generally emulates the following data:
The level of AdBlue in the tank: the emulator sends data to the engine management system indicating that the AdBlue tank is full and that there is no fault in the system.
The flow of AdBlue injected into the SCR system: the emulator sends data to the engine management system indicating that the flow of AdBlue is normal and that there is no fault in the system.
AdBlue system fault codes: The emulator sends data to the engine management system indicating that there are no faults in the AdBlue system.
The purpose of the emulator is to trick the engine management system by sending dummy data to it, in order to disable or bypass the AdBlue system and allow the vehicle to drive without using AdBlue. However, using an AdBlue emulator is illegal in many countries and can lead to penalties if checked.
To know a little more about this type of intervention
We also have the possibility of reprogramming your vehicle for an improvement in power, torque and consumption. You can also find all our interventions on DAF Euro 5 and DAF Euro 6.
