1. 1

   Check the Power Supply: The primary cause of this fault is a loss of voltage supply for the CAN-Bus on the A013 printed circuit board.

2. 2

   Inspect Fuses: Check microfuses F040 and F041 located on the A013 fuse board.

3. 3

   Wiring Inspection: Check the CAN-Bus wiring for continuity, breaks, or short circuits to earth (reference Wiring Diagram Sheet 22 / 6).

4. 4

   Connector Checks: Inspect the connections between the A002 EST Control Module (e.g., Pin 26, Connector X031) and the A013 fuse board (e.g., Pin A6 (+), Connector X200).

1. 1

   Turn ignition ON

   Turn the tractor's ignition to the "ON" position.

2. 2

   Locate fuse board

   Locate the A013 printed circuit board (fuse board).

3. 3

   Inspect and replace fuses

   Pull and inspect fuses F040 and F041. If either fuse is blown, replace it with a new microfuse of the correct amperage.

4. 4

   Measure voltage supply

   If the fuses are intact, use a multimeter to measure the voltage supply on the A013 board (Pin A6 (+), Connector X200 against earth) to ensure the board is outputting the correct voltage to the CAN-Bus.

5. 5

   Check wiring and connectors

   If the voltage is missing or incorrect, check the wiring harnesses (WF1492, WF1744) and connectors for damage.

6. 6

   Replace hardware

   If the wiring is completely intact and the fuses are good, the fault lies within the hardware. You will need to replace either the A013 printed circuit board or the A002 ECU.
