1. 1

   Connect the Massey Ferguson EDT (Electronic Diagnostic Tool) to verify the active error code and monitor the live voltage reading for the X130 FingerTIP 6 switch.

2. 2

   Inspect harness junctions X132 (instrument panel/armrest), X133 (console/cab transmission), and X134 (console/pillar) for pinched wires, chafing, or moisture.

3. 3

   Disconnect the X130 FingerTIP 6 switch and test the switch terminals with a multimeter to determine if the short to 0 V is internal to the switch or on the harness side.

1. 1

   Disconnect Power

   Disconnect the tractor's battery to prevent further electrical damage to the Armrest Autotronic 5 module.

2. 2

   Access the Armrest

   Carefully disassemble the armrest console to access the underside of the FingerTIP control module (X130).

3. 3

   Isolate the Short

   If the diagnostic checks revealed a harness issue at junctions X132, X133, or X134, repair the damaged wire insulation or replace the affected harness section.

4. 4

   Replace the Switch (if necessary)

   If the switch itself failed the continuity test (internal short to ground), remove the faulty FingerTIP 6 switch and install the replacement unit.

5. 5

   Reassemble and Reconnect

   Reassemble the armrest console and reconnect the battery.

6. 6

   Recalibrate

   Using the EDT diagnostic tool, you must perform the "Calibration of the FingerTIP controls on the armrest" procedure to ensure the Autotronic 5 module recognizes the full sweep of the new or repaired switch. Clear the AR 61 fault code.
