1. 1

   Verify battery voltage is within normal operating range (12V-14V) and check for related voltage codes (e.g., T130 - Transmission Module Low Supply Voltage)

2. 2

   Inspect the wiring harness and connectors going to the Autotronic transmission controller for moisture, corrosion, or loose pins

3. 3

   Check if the Dash module is logging any CAN BUS communication errors from the transmission module

4. 4

   Clear the fault codes and perform a key cycle (hard reset) to see if the software error was a momentary glitch

1. 1

   Software Re-flash

   If the code remains active after a reset and voltage checks pass, connect the Massey Ferguson Electronic Diagnostic Tool (EDT). Attempt to re-flash or update the software on the Autotronic Transmission Controller.

2. 2

   Module Replacement

   If the controller will not accept the software update, or if the internal memory (EEPROM) is permanently corrupted, the Autotronic unit must be replaced.

3. 3

   Programming

   A new Autotronic controller must be programmed using an Autotronic conversion programming kit or dealer software to match the tractor's specific transmission type (Dyna-4, Dyna-6, or Dyna-VT).

4. 4

   Calibration

   After installation and programming, perform a full transmission and pedal calibration.
