TROUBLESHOOTING

This is a result of communication error between the control box and the ECM. This could be a result of cable damage control box cable. It could also be a broken cable or a bad connection anywhere through the wiring harness to the ECM.

Joystick potentiometer not centered This basically means the joystick is not centralised correctly at the point where you turn your machine on. This can be repaired, however depending on the condition of joystick you may just want to replace it

your machine has an issue with the pothole limit switches, wiring or ecm

Check Pothole Limit Switches

There are two pothole limit switches which are activated when the pothole guards are deployed. Check whether both switch a being made when lowered and released when the platform is raised.

Gas Struts Weak

Often if one of your gas struts become weak it can result in one of the switches not being fully pressed. With the platform raised you should be able to physically press each switch. If the switch looks in good condition and you can feel the switch opening and closing the contacts I would check the condition of the cables and connectors where they joint back into the harness.

Still Not Resolved The Issue

If you don’t find the fault at this point you would need to check the limit switch are working correctly with a multi meter. And then check continuity or voltage back to B10 input on the ECM.
