The error code 520538-4 indicating a short circuit to ground in the DEF heating element is a serious issue and can affect the performance of the vehicle. The DEF system is critical for the vehicle to meet emission standards and should be addressed as soon as possible.
Since you have already replaced all of the DEF system components and even the ECU and the problem still persists, there are a few other things that you can check:

1. Wiring harness: Check the wiring harness that connects the DEF heating element to the rest of the vehicle's electrical system for any damage or loose connections.
2. DEF Pump: The DEF pump may have a failure that causes the DEF not to flow properly.
3. DEF Dosing Unit: Check the DEF dosing unit for any clogs or damage.
4. DEF Quality: Make sure that the DEF being used is of the correct quality and specification.
5. Software update: Check with the dealer or the manufacturer if there is any software update available that can fix the issue.

It's highly recommended to have a professional technician diagnose and fix the problem as it's a critical emission component and might cause further issues if not addressed properly. The technician can use a diagnostic tool to check the system in more detail and locate the exact problem.

We aren't Forklift experts here at Fixya. You need a Doosan Service Tech on that one. Any subsequent failure causing dea th becomes their responsibility.

check engine means problem so when problem fixed light will go out

Hi Kevin Be careful as there are two units for Ton I.e. Tonne

One is a British Ton ( imperial) one is a metric Tonne American.
The British Ton is equal to1,016.047 kg x 9 = 9 Ton
The American Tonne is equal to 1000kg x 9 = 9 Tonne
If you need to be accurate do the sums however if an approximation works 9000kg = 9 ton

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master.
It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

I doubt it but that is just my opinion

Good morning

ON MANY OF THE -5 RANGE OF THE TEIR2 & TEIR3 DOOSAN TRUCKS (ORANGE IN COLOUR) HAVE FLYBY WIRE THROTTLE, YOU CAN USE DIAGNOSTICS TO READ THE CODES BUT THE TRUCK ALLOWS YOU TO READ THE FLASH CODES BY TURNING THE KEY TO THE FIRST POSITION (IGN LIGHTS ON) AND PRESSING THE ACC PEDAL UP AND DOWN FULLY 5 TIMES IN 3 SECONDS AND THE MIL LIGHT WILL FLASH OUT 3 DIGIT CODES UNTIL YOU READ A 2 DIGIT CODE WHICH IS 12 AND THATS THEM RETURNING BACK TO THE START AND THEY WILL REPEAT AGAIN. TO CLEAR THE CODES TURN THE KEY OFF AND BACK ONTO THE FIRST POSITION AND PRESS THE ACC PEDAL UP AND DOWN 10 TIMES IN 5 SECONDS TO CLEAR ALL CODES FROM THE ECU. THERE A LOT OF PHANTOM CODES THAT DOOSANS BEEN CHANGING THE SOFTWARE TO TRY AND ELIMINATE SO IT WOULD MAYBE BE A GOOD IDEA TO HAVE UR SOFTWARE UPGRADED (5MIN JOB). ALSO A LOT OF CODES ARE THROWN UP DUE TO THE WIRING LOOM THAT RUNS OVER THE INLET MANIFOLD THE RIBS ON THE SHEVIN WEAR THE WIRING IN THAT PART OF THE LOOM AND THEY SHORT AND THROW UP CONSTANT CODES. ANY ISSUES WITH CODES JUST CONTACT ME.........
