John Deere 524155.05 – TCU: CR - Proportional Solenoid Valve for Reverse Clutch, Current Too Low

The control unit has registered a resistance at the proportional solenoid valve that does not correspond with the expected switch status, meaning the circuit of the proportional solenoid valve is open and the current is too low.

1. 1

   Check for related supply voltage codes (specifically TCU 524154.05), which indicates a general problem with the supply voltage of the proportional solenoid valves (lead 6046)

2. 2

   Inspect the solenoid valve circuit wiring for any signs of disconnection or breaks that would cause an open circuit

3. 3

   Verify all electrical connections to the solenoid are secure and free of corrosion

4. 4

   Test the solenoid valve by using a multimeter to measure the current at the signal input of the CR proportional solenoid valve

1. 1

   Address related DTCs

   Address any related DTCs first. Specifically, process TCU 524154.05 to ensure the general supply voltage to the transmission valves is intact.

2. 2

   Locate solenoid valve

   Locate the CR Proportional Solenoid Valve for the reverse clutch on the transmission valve block.

3. 3

   Inspect wiring and connectors

   Inspect the wiring and connectors associated with the solenoid valve for physical damage, corrosion, or disconnection.

4. 4

   Repair or replace wiring

   Repair or replace any damaged wiring harness components or connectors.

5. 5

   Measure current and resistance

   Use a multimeter to measure the current draw and resistance at the signal input of the CR proportional solenoid valve.

6. 6

   Replace solenoid valve

   If the solenoid valve is not drawing sufficient current (indicating an internal open circuit or failure), replace the solenoid valve.
