John Deere 002036.09 – TID: CAN BUS Message Fault in Direct Drive Gear Shift Module

A communication failure has occurred on the CAN bus involving the Direct Drive Gear Shift Module (TID). The FMI .09 indicates an abnormal update rate or a loss of communication, meaning other control units on the network are not receiving expected messages from the gear shift module. This points to an intermittent or complete breakdown in communication that may affect the proper operation of the gear shift system.

1. 1

   Visually inspect wiring harnesses connected to the DirectDrive transmission and gear shift module for chafing, pinching, corrosion, or rodent damage. Pay close attention to harness routing and ensure it is not rubbing against any part of the tractor frame or other components.

2. 2

   Inspect main battery and chassis ground connections to ensure they are clean, tight, and free of corrosion.

3. 3

   Verify the Direct Drive Gear Shift Module (TID) is receiving the correct power supply voltage and has a solid ground connection.

4. 4

   Perform a CAN bus resistance check at the diagnostic connector with the battery disconnected (expected: ~60 Ohms between CAN High (Yellow wire) and CAN Low (Green wire)).

5. 5

   Perform a CAN bus voltage check with the key on (expected: ~2.5V on both CAN High and CAN Low lines).

6. 6

   Conduct a wiggle test on the wiring harnesses and connectors while observing CAN bus voltages to pinpoint intermittent faults.

1. 1

   Repair wiring and grounds

   Fix any identified issues with wiring, connectors, or ground connections. Repair damaged wires, clean corroded terminals, or replace faulty ground straps.

2. 2

   Isolate faulty component

   If the wiring and connections appear to be in good condition, disconnect other control modules on the same CAN bus one at a time to see if communication with the TID module is restored. Note that locating and identifying all modules requires a technical manual and can be complex.

3. 3

   Check terminating resistors

   If the CAN bus resistance check read 120 Ohms, locate and test the two terminating resistors on the network. Replace any missing or faulty resistors. The location of these resistors can vary and is best identified using a service manual's wiring diagram.

4. 4

   Replace Gear Shift Module (TID)

   If all wiring and network checks pass and the fault persists, the TID module itself may be faulty. Have a dealer confirm the diagnosis using Service Advisor software before replacement, as a new module requires programming and calibration.
