Im getting this error code.

Hello

Measurements with a multimeter necessary.
Measure fuel pump for continuity. approx 0.2 ohms.
if that's true, then renew fuel pump, electronic  part number  16148523262

Hope this helps

Garagemdozezo:
You mean the three wires? or the two ones? The two ones are for the fuel pump eletronic right? I disconnected the ignition coils plugs, the gs911 let me clear the error now, but when starting it it pops up again. I already opened and changed the pump refill. I also exchanged the fuel tank with another GS 1200 that I have here in the store. Nothing either.

schuppi:
No, 2 are for the fuel pump and 3 are for controlling the pump electronics.

You can try to isolate the problem.
Remove 2 wire cables from the pump. Erase the fault memory, then start the engine, check the fault memory to see whether the fault occurs again. If not, then the pump is defective.
If so, remove the 3-wire cable from the electronics.
Erase the fault memory, then start the engine, check the fault memory to see whether the fault occurs again.
If not, the electronics are defective.
If so, check the wiring to the ZFE for a short circuit.
If OK , then ZFE defective
