How did you determine the controller was bad?

 

[jcb jeff]

Are the switches adjusted correctly which means when washer passes the blue switch the led will light up on these the front switch locks out the back and vise versa .check wiring on the plugs at the switch connectors at the chassis plug for the harness.Check fuses is the mode switch on dash working correctly .You can flash a spanner across the switches on the blue part and it should change modes .Make sure the blue plastic bits on switches is not damaged
Can you get front and rear wheels straight if not it wont lock out .

 

[jcb jeff]

Might need to re phaze steering but i guess the rear switch not aligning so wont change modes also check wiring on solenoids for steer mode at base of cab front right

The wheels are straight on the back.only front ones turning.mode light flashing up code 13 on the dash.

The switches front and back are turning on and off.checked with spanner already
