Massey Ferguson 0B.01.02 – Implement/Hydraulic Control Module or Mid-Mount Valve Controller: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

The tractor's control module is detecting that the electrical current (amperage) flowing through the mid-mount loader valve solenoid circuit is lower than the expected threshold. This condition typically points to high electrical resistance, a loose or corroded connector, damaged wiring (partial open circuit), or a failing solenoid coil on the loader's hydraulic valve block.

1. 1

   Visual Inspection: Inspect the wiring harness leading to the mid-mount electro-hydraulic valve block (usually located on the right side of the chassis, under the cab). Look for pinched wires, chafing, or debris damage.

2. 2

   Connector Check: Disconnect the harness at the affected solenoid. Check for water ingress, dirt, or corroded pins. Clean the contacts and ensure a tight connection.

3. 3

   Resistance Test (Ohms): Use a multimeter to measure the resistance across the solenoid coil pins. A 'Low Amp Draw' often means the coil's internal resistance has become too high. Compare the reading to a known good solenoid on the same valve block.

4. 4

   Voltage/Signal Test: Actuate the loader joystick and verify that the controller is sending the correct voltage to the solenoid connector.

5. 5

   Check Spool Sensors: Ensure there are no accompanying spool position sensor faults (e.g., M17, M18, M19, M20, M21), which can sometimes trigger alongside valve actuation issues.

1. 1

   Safety First

   Lower the loader to the ground, turn off the tractor, and cycle the loader joystick to relieve all residual hydraulic pressure in the system.

2. 2

   Locate the Valve

   Access the mid-mount electro valve block.

3. 3

   Disconnect

   Unplug the electrical connector from the faulty solenoid.

4. 4

   Remove the Coil

   Remove the retaining nut or clip at the end of the valve cartridge stem. Carefully slide the old solenoid coil off the stem. (Note: You usually do not need to remove the hydraulic cartridge itself, which prevents fluid loss).

5. 5

   Clean and Inspect

   Wipe down the valve stem. Check for any signs of hydraulic fluid leaking from the cartridge, which could short out the new coil.

6. 6

   Install New Part

   Slide the new solenoid coil onto the valve stem and secure it with the retaining nut/clip. Do not overtighten.

7. 7

   Reconnect

   Plug the electrical harness back into the new solenoid.

8. 8

   Test and Clear

   Start the tractor, test the loader functions for proper operation, and use a compatible diagnostic tool to clear the 0B.01.02 fault code from the system.
