John Deere 2002.09 – ECU / ICU: No CAN Message Received From Source Address 2

The controller logging the code has lost CAN bus communication with the module assigned to Source Address 2. The FMI 09 identifier specifically denotes an abnormal update rate, a timeout, or a missing message.

1. 1

   Cycle power by restarting the engine to see if the code was caused by a transient communication glitch.

2. 2

   Visually inspect the CAN Bus wiring and connectors between the ECU/ICU and the Source Address 2 module for frayed wires, chafing, or loose connections.

3. 3

   Disconnect the harness at the ECU and the Source Address 2 module to check for moisture, bent pins, or corrosion.

4. 4

   With the battery disconnected, test CAN Bus resistance across the CAN High and CAN Low pins (should read approximately 60 ohms; 120 ohms indicates a faulty terminating resistor or open circuit, 0 ohms indicates a short).

5. 5

   Verify the module at Source Address 2 is receiving proper voltage and has a solid ground.

6. 6

   Use John Deere Service ADVISOR to ping the modules on the network and verify exactly which module has dropped off the bus.

1. 1

   Disconnect Power

   Disconnect the negative battery cable before performing any electrical repairs.

2. 2

   Repair Wiring

   If the visual inspection revealed damaged wiring (e.g., rodent damage or chafing against the chassis), splice and seal the wires using John Deere approved heat-shrink connectors, or replace the affected harness section.

3. 3

   Replace Terminating Resistors

   If the CAN bus resistance check failed (reading 120 ohms instead of 60 ohms), locate and replace the faulty CAN bus terminating resistor.

4. 4

   Address the Source Address 2 Module

   If the wiring and resistors are perfectly intact and the module has power/ground but still won't communicate, the module itself has likely failed internally and must be replaced.

5. 5

   Reassemble and Clear Codes

   Reconnect the battery, turn the key to the ON position, and use a diagnostic tool to clear the stored 002002.09 fault code.

6. 6

   Test Operation

   Start the engine and monitor the system to ensure normal operation and verify the code does not return.
