Explanation

The frame contact sensors sense when the top lift frame is resting on top of the container. There is a sensor for each corner of the top lift frame. One of the switches is reporting incorrect information.

Causes

• Faulty contact sensor switch
• Faulty contact sensor switch wiring

Operator Actions

• Use override code to continue operation
• Request service

Service Tasks

• Each contact sensor switch has complementary outputs (i.e. Normally Open and Normally Closed switches). If the Front ECU detects that both contact sensor switch outputs are the same state then the error message will be displayed.
• The contact sensor switch cable is either shorting or broken, or the contact sensor switch has failed.
• Swap the contact sensor switch with one from another corner of the frame and see if the error moves with the switch.
