Resolving an adblue fault on DAF XF105.460
How to permanently remove an adblue fault on DAF XF105.460
The AdBlue defect on a DAF XF105.460 can have several causes. The P2100 and the U0113 reduce engine performance. First, let's see what these faults are, and then we'll 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 limits engine performance in order to reduce pollutant emissions. This can result in a reduction in power and maximum vehicle speed.
The probable cause is fault U0113 :
Error message U0113 indicates 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 may be either too high or too low. This type of fault can have several causes. It may be a problem with the AdBlue system itself, such as a faulty sensor or damaged electrical circuit. It may also be a problem with the vehicle's communication network, such as a damaged cable or faulty interface.
In view of 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 an AdBlue SCR system, with the aim of bypassing or deactivating the system. Fitting an emulator to a DAF 105.460 will enable the truck to regain its torque and power, and thus restore its nominal efficiency. The AdBlue emulator is mounted on the truck's CANbus network.
In general, here's how an AdBlue emulator can be mounted on a vehicle:
- Locate the vehicle's OBD II (On-Board Diagnostic) connector. It's usually located under the dashboard, near the steering column.
- Connect the emulator to the OBD II connector, making sure that the wire colors match those of the connector pins.
- Connect the emulator to the vehicle's 12/24V power supply, either via the cigarette-lighter socket or directly to the vehicle's 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 a vehicle electronics box under the grille.
What data is virtualized by our box?
- AdBlue tank level: the emulator sends data to the engine management system indicating that the AdBlue tank is full and that there are no faults in the system.
- AdBlue flow rate injected into the SCR system: the emulator sends data to the engine management system indicating that the AdBlue flow rate is normal and that there are no faults 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 aim of the emulator is to deceive the engine management system by sending it fictitious data, in order to disable or bypass the AdBlue system and allow the vehicle to run without using AdBlue. However, the use of an AdBlue emulator is illegal in many countries, and may result in penalties in the event of an inspection.
