Massey Ferguson 13.00.42 – HITCH: Park Brake Released Solenoid Low Amp Draw

The controller is detecting a lower-than-expected electrical current (amperage) when it attempts to energize the solenoid responsible for releasing the park brake, indicating an open circuit typically caused by a broken wire, disconnected/corroded connector, or failed solenoid coil.

1. 1

   Verify that the fuse supplying power to the park brake circuit is intact.

2. 2

   Locate the Park Brake Released Solenoid on the transmission valve block and inspect the wiring harness and connector for frayed wires, corrosion, or loose pins.

3. 3

   Disconnect the electrical connector from the solenoid and use a multimeter to measure the resistance (Ohms) across the pins of the solenoid coil. An 'OL' (open line) reading or extremely high resistance confirms the coil has failed internally.

4. 4

   If the coil tests good, check the wiring harness for continuity between the solenoid connector and the HITCH controller pins to look for a broken wire or a short to ground.

5. 5

   With the tractor running and the park brake commanded to release, check for voltage at the harness connector to ensure the HITCH controller is sending the signal.

1. 1

   Secure the Machine

   Park the tractor on level ground, turn off the engine, and securely chock the wheels.

2. 2

   Locate the Solenoid

   Identify the Park Brake Released Solenoid on the transmission's electro-hydraulic valve block.

3. 3

   Disconnect

   Unplug the electrical connector from the solenoid.

4. 4

   Remove the Coil

   Remove the retaining nut or clip at the end of the solenoid valve stem. Slide the faulty electromagnetic coil off the valve cartridge.

5. 5

   Install the New Coil

   Slide the new OEM solenoid coil onto the valve stem and secure it with the retaining nut/clip.

6. 6

   Reconnect

   Plug the electrical connector back into the new solenoid.

7. 7

   Clear Codes & Calibrate

   Turn the key on and use the tractor's diagnostic terminal to clear the 13.00.42 fault code. Depending on the model, a transmission/PowerShuttle calibration may be required after replacing transmission solenoids.

8. 8

   Test

   Start the tractor and cycle the park brake switch to ensure the brake engages and releases properly without throwing the code.
