Internal malfunction in the control unit.

Notes:

As a result of a fault, the SCR system shuts down and the reagent injection shuts down.

When the SCR system is turned off, DTCs 42256, 43345, and 43361 related to data transmission for the SCR system can be generated. Perform a primary troubleshooting using this fault code.

When the SCR system is disabled, data transfer between the SCR control unit and the engine control unit may be interrupted. To ensure correct handling of the DTC, control units must be able to communicate with each other. To restore communication, turn off the ignition and wait 90 seconds before turning it on again.

High temperatures in the SCR system may cause decomposition of the reagent.

Elimination:

Check whether the water valve is open in the open position.
If the fault lies in the main unit, the main unit should be replaced.
To check if the malfunction has been fixed and if the malfunction code does not occur again, you can click on the malfunction code monitoring function and view the malfunction code. This DTC is not generated immediately. In order for the control unit to generate an active fault code, the fault causing the code generation must occur in four consecutive cycles, that is, the ignition must be turned off and on four times. To see if the DTC is in the process of being considered, that is, whether a DTC is generated, you can use the DTC Monitoring feature.

Voltage supply for SCR control unit

Fault:

The SCR control unit turns off too soon. The power to the SCR system was turned off before the system was turned off.

The reasons:

If the car has a mass switch (used in buses and ADR cars), a fault code can be generated if the battery mass switch is used within 90 seconds after the ignition is turned off.
There may be a fault in the supply voltage to the SCR system.
In addition, the malfunction may be due to an internal malfunction in the control unit.

Communication between the engine control unit and the SCR control unit or between the SCR control unit and the NOx sensor is interrupted.
If fault code 5688 was simultaneously generated, there may be a problem in the communication between the engine control unit and the SCR control unit.
If fault code 5688 was simultaneously generated, there may be a communication failure between the SCR control unit and the NOx sensor.
If the DTC was generated only once, it may be due to the interruption of the voltage supply to the NOx sensor while maintaining the voltage supply to the SCR control unit.
The SCR control unit in the main unit may be faulty.
If a fault code is generated frequently, it may be due to a problem in the wiring harness or connectors.

Notes:

As a result of a fault, the injection of the reagent is turned off.

Fault codes are generated based on information from the SCR control unit. If there is no communication between the SCR control unit and the engine control unit, no SCR related fault codes are generated in the engine control unit.

If this DTC is generated, there is no communication between the engine control unit and the SCR control unit. This may imply that there are no SCRs related to the SCR in the engine control unit, and those that have been erased will not be generated again, even if there is still a fault.

Elimination:

Also check for DTCs related to CAN communication in other control units. Troubleshoot these problems first.
Switch off the ignition and wait for 90 seconds before turning it on again.
If there are fault codes for the SCR system, first diagnose them.
Switch the ignition on and off several times. Fault codes that were not generated in the engine control unit could be present in the SCR control unit, because this fault code is active.
If the DTC recurs and the DTC does not indicate that the SCR system is off, check the wiring and fuses for the SCR system and clean the electrical connectors.
Also make sure that both control units simultaneously receive voltage (U15).
