John Deere 002007.09 – BLC: CAN BUS PTO Module Message Issue

The fault code indicates an internal message issue within the Main Controller (BLC), specifically a communication breakdown with the PTO Module over the CAN BUS network. The Main Controller is not receiving the expected data messages from the PTO module, which typically results in a loss of PTO functionality.

1. 1

   Check the diagnostic display for other active fault codes, especially those related to power supply or other control modules, which could indicate a wider network issue

2. 2

   Inspect fuses related to the PTO and control modules to ensure a module hasn't lost power

3. 3

   Visually inspect the wiring harness and connectors between the PTO module, the main control module, and related components for damage, corrosion, or loose connections

4. 4

   Check CAN BUS voltage with the key on and engine off (CAN High and CAN Low should both read approximately 2.5 volts)

5. 5

   Check CAN BUS resistance with the battery disconnected (should read approximately 60 ohms; a reading of 120 ohms indicates a problem with a terminating resistor)

6. 6

   Restart the tractor to see if a simple power cycle re-establishes communication between the modules

1. 1

   Address related fault codes

   Resolve any other active fault codes first, particularly those affecting power supply or other control modules on the CAN network.

2. 2

   Perform diagnostic checks

   Perform the diagnostic checks listed above.

3. 3

   Isolate the CAN BUS network

   If wiring and connectors appear to be in good condition, disconnect other control modules on the CAN BUS one at a time to see if the fault code disappears. This identifies if another faulty module is disrupting the network.

4. 4

   Test the PTO solenoid

   If CAN BUS communication is verified as intact, test the PTO solenoid for proper operation by checking for a clicking sound when power is applied or by measuring its resistance.

5. 5

   Swap suspected components

   If a faulty module or terminating resistor is suspected, swap the component with a known good unit to confirm the diagnosis before purchasing a replacement.

6. 6

   Consult the Official Service Manual

   Consult the official John Deere technical manual for the specific tractor model or use Operations Center™ PRO Service for detailed diagnostic and repair procedures.
