jungheinrich EFG-V-16 forklift with error code 28

Can someone tell me what the error code 28 means at a Jungheinrich forklift truck model EFG-V-16? So now en then the truck goes into this error and nothing works any more.
Can someone supply me with the drawings of the controller board. I have looked at the wiring of the truck. All looks good. I think some parts on the electronic controller board have some error so that there is so now en then no energie to switch on the FET's.

I think this relates to the steer pot error. Possibly a faulty steer pot or a broken wire in the loom. Perhaps someone can confirm that is the correct code info.

On the steer colon I only find a oil pressure switch. the steering is hydrolic.

Sorry I think that was for the ac version truck. The 28 code states that the current sensor is defective. I think the LED flashes 4 times on the card.

Elektrodrive is correct. You should have a flashing code on the traction controller 4x. It means you have a fault in current sensor. Change the pcb according to the book :)

Thanks Elektrodrive and Billy B for your answers.

I have now an idea where to look. Probably the inductor coil. It's a big heavy part on the PCB.
The forklift truck rides on e area with stelcon plates on the ground. I can expect that the connection wire is broken.

Can one of you supply me with electronic (pricipal) drawings of this controller board?
What price must I expect when I buy this controller board?

regards
