The Hitachi Controllers on the Nissans, if its the one with the 2 logic cards that slots downwards into the panel, then most likely you have a problem on the largeer of the 2 logic cards. We have had them in the past where the tracks corrode away and also being double sided pcb's and with loads of lacquer its difficult to to test. Try soldering the joints on the card.

Hello

Its a small Hytachi controller and the print is not good. ( I have changed him with a other truck.

Thanks for the replys.
But some information on pdf good be nice perhaps whe can share something.

Cheers

if its any thing like the model i'm thinking of, it will have to black rely's down by the power steering motor. (there a pig to get at or even see)

try disconecting these and bridge them out.

Has the truck still got power steering?

Has the truck still got power steering?

I wouldnt mind the information if you manage to get hold of it. In the meantime, do you know what controller this truck uses? As i may have info on the control system depending on what Nissan have used on this specific truck.
