I will briefly describe how to diagnose the operation of the Ls valve.
-
Tighten the overflow valve so that the bolt protrudes 1.6mm above the locknut.
-
Turn off the turn sensor
-
turn on the steering in test mode if the tractor icon, steering wheel and compass in the lower right corner are green and the PWM value is around 100.
-
start the engine and try to turn the steering wheel (it should be locked both to the left and to the right)
-
Try to steer by pressing the arrows (the wheels should turn)
-
If the wheels cannot be steered with the arrows, check if they will steer if you try to turn the locked steering wheel and use the arrow keys at the same time, if this test is positive, the problem is related to Ls
-
If the wheels still have not moved, check if the coils of the proportional valve are getting power from the citron, if you unscrew the nut securing the coil and try to remove it from the valve, you will feel the electromagnetic force pulls it onto the core, i.e. the coil is working properly.
-
If the coils are OK, check that the hydraulic hose connections are correct.
