SAS light on

Toyota 7FGU70

I know nothing about how to troubleshoot this. The light is usually on when I start the truck. When I raise the forks and drop them, I see a amber indicator in the shape of an H come on. then both lights go out. Truck has a potentiometer on the tilt, a switch on the right side of the two stage mast, and a sensor in the hydraulic line between the main lift cylinders. How do I troubleshoot this?

Not sure but I will give it a shot. I find that the rubber mounts for the control valve are worn. Or the spring in the tilt spool is week, or the switch in the tilt spool is intermittent. All this assuming you have the SAS/ OPPS system on this lift. Anyway, causes the switch in the tilt spool to be engaged when it should not be. If the fault is there, by hand center the tilt lever, the light might go out. if it dose, you found it. Good luck, some of the things I have found.

Liftdoctor, I think that the dash should display some code. I have run into this before and it was a broken harness going up to the mast switch.
Dimitry I have never seen a code 56 before. Do you have a different model than Liftdoctor?
