Bobcat H2407 (24-07) Fault Code: Rear Rod Solenoid Open Circuit

Also shown on the panel as 24-07 · Also called Rear Rod Output Open Circuit

Rear Rod Solenoid Open Circuit · ai-assisted, editor-reviewed · Last updated 2026-07-13

TL;DR

Bobcat code H2407 (panel form 24-07) means the auxiliary controller sees an open circuit on the rear rod solenoid, signal wire 4430, or return wire 2430. When it sets, the controller disables the rear rod solenoid, which cuts hydraulic flow through the rear auxiliary male coupler.

Medium severity. H2407 does not damage the machine, but it disables a hydraulic auxiliary function you likely need for attachment work. Diagnose it before relying on the rear auxiliary coupler for any job.

What does Bobcat error code H2407 mean?

H2407 is set when the auxiliary controller detects an open circuit related to the rear rod solenoid. This solenoid directs hydraulic flow through the rear auxiliary male coupler, which typically feeds one side of an attachment's hydraulic function.

When the controller detects the open circuit, whether on the solenoid coil itself, signal wire 4430, or return wire 2430, it disables the rear rod solenoid outright rather than let it operate erratically. This means the rear auxiliary function tied to this solenoid will not work until the fault is fixed.

This is a wiring and component integrity fault, not a hydraulic pressure or fluid-quality fault. The root cause is almost always electrical: a break, short, or bad connection somewhere between the controller and the solenoid.

Common causes of H2407

  • Signal wire 4430 shorted to supply voltage or open
  • Return wire 2430 open
  • Faulty rear rod solenoid
  • Faulty auxiliary controller
  • Moisture, corrosion, or pushed-back pins in the auxiliary controller connectors, rear rod solenoid connector, or mainframe harness
  • Intermittent faults from loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these, which may not be found if the fault is not active during testing

How to troubleshoot Bobcat H2407: first checks

  1. Turn the key switch / run-enter switch on since this is a required condition for the code to be active and testable
  2. Inspect the rear rod solenoid connector and the auxiliary controller connectors for moisture, corrosion, or pins that have pushed back out of the connector body
  3. Trace signal wire 4430 for a short to supply voltage or an open circuit
  4. Trace return wire 2430 for an open circuit
  5. Check the mainframe harness along the routing to the rear auxiliary coupler area for chafing, pinches, or corrosion
  6. Test the rear rod solenoid coil itself for proper resistance and continuity
  7. If the fault does not appear active during testing, wiggle-test connectors and harness sections to try to reproduce an intermittent open circuit

How the code clears

Once the wiring, connector, solenoid, or controller issue is repaired, clear the code by cycling power on the machine. No separate clearing step is listed beyond cycling power.

Frequently asked questions

What does Bobcat code H2407 mean?

It means the auxiliary controller found an open circuit tied to the rear rod solenoid, either in the solenoid itself, signal wire 4430, or return wire 2430. The controller responds by disabling the rear rod solenoid.

What is the panel display number for H2407?

On the panel it shows as 24-07.

Will H2407 stop my machine from running?

No, it disables the rear rod solenoid function, which affects hydraulic flow through the rear auxiliary male coupler. The rest of the machine keeps running, but that auxiliary function will not work until the fault is fixed.

Which Bobcat models can show code H2407?

It applies to S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770, and T870.

How do I clear H2407 after repair?

Cycle power on the machine. No separate clearing procedure beyond a power cycle is listed.

Why does H2407 come and go instead of staying on?

If the fault is intermittent, the cause may be a loose connection, corrosion, a pushed-back pin, an issue with the controller, or a wire harness problem, or a combination of these. Intermittent faults can be hard to catch if they are not active during testing.

What should I check first if I get H2407?

Start with the connectors: the auxiliary controller connectors, the rear rod solenoid connector, and the mainframe harness, looking for moisture, corrosion, or pushed-back pins. Then check wires 4430 and 2430 for opens or shorts.
