In the electronic control system of diesel vehicles, there is a protection mechanism for the DPF filter system. When the ECU computer detects that the efficiency of the DPF has decreased or is abnormal, it will issue an instruction to limit the torque output of the engine.
In layman’s terms, it means that you can’t refuel, you can’t run, and you can only run 80 yards at most. . . And it will report fault code P2463
Here car-auto-repair.com show you guide on how to disable DPF for BOSCH EDC17C81 EDC17C53 EDC17C63 by manual.More DPF disable topics,please refer to:DPF Clean/Disabled
Steps:
Step 1:Read out ECU Data
Use ECU Read/Write programmer to read out ECU data,like KTAG,Dimsport,PCMflash…
Notice:your device need checksum function,otherwise it can not work well.
Here take PCMflash as example
According to the diagram wires to build connection
Run PCMflash to read out ECU data
For DPF disable,only need read out Flash data to save,no need EEPROM
But in case of damaged,both ECU files backup recommeneded
Step 2:Modify Flash file
Use Hexworkshop software to open Flash file read out from ECU
Then search “8813000088”
Find below digits “00 00 01 00 88 13 00 00 88”
Now change it to “00 00 00 00 88 13 00 00 88”
If you can not find “00 00 01 00 88 13 00 00 88”,please search “2C01080001”
Now change “2C01080001” to “2C01080000”
Step 3:Write Modified Flash File back to ECU
Use ECU programmer write the modified Flash file back to ECU
Finally,install ECU to cars to test.
