Bobcat H2707 (27-07) Fault Code: Front Rod Solenoid Open Circuit
Also shown on the panel as 27-07 · Also called Front Rod Output Open Circuit
Front Rod Solenoid Open Circuit · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
H2707 sets when the auxiliary controller (or deluxe MX controller on some machines) detects an open circuit on the front rod solenoid, either on signal wire 4330/4110 or return wire 2330/2110. The panel form is 27-07. When it sets, the front rod solenoid, which directs hydraulic flow through the front auxiliary male coupler, is disabled.
Medium severity. This code disables one hydraulic function (front rod auxiliary flow) rather than the whole machine. It is not an emergency, but it will stop you from using front-mounted attachments that rely on the front rod circuit until it is fixed.
What does Bobcat error code H2707 mean?
H2707 is Bobcat's code for an open circuit on the front rod solenoid circuit, tracked by either the auxiliary controller or, on machines with the deluxe MX control package, the deluxe MX controller. The controller monitors signal wire 4330 (or 4110 on deluxe MX systems) and return wire 2330 (or 2110), and when it sees an open on either wire, it flags H2707 and shuts the front rod solenoid off.
The front rod solenoid controls hydraulic flow direction through the front auxiliary male coupler, which is what feeds many front-mounted attachments. Once the code sets and the solenoid is disabled, that flow path will not work correctly until the fault is cleared and the circuit is repaired.
This code applies across a wide range of Bobcat skid steer, compact track loader, and compact excavator models, including the E35, E45, S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770.
Common causes of H2707
- Signal wire 4330 (or 4110 on deluxe MX systems) shorted to supply voltage or open
- Return wire 2330 (or 2110 on deluxe MX systems) open
- A failed front rod solenoid
- A failed auxiliary controller or deluxe MX controller
- Moisture, corrosion, or pushed-back pins in the auxiliary controller connector, deluxe MX controller connectors, front rod solenoid connector, mainframe harness, or deluxe MX power/control harness
- An intermittent fault that is not present at the time of testing. In these cases the root cause may be a combination of loose connections, corrosion, pushed-back pins, the controller itself, or the wiring harness, and it may not be pinpointed on the first pass
How to troubleshoot Bobcat H2707: first checks
- Confirm the key switch is in the run/enter position, since the controller only checks this circuit under that condition. On deluxe MX systems, also confirm auxiliaries are enabled and a front rod command is being issued
- Inspect the front rod solenoid connector and the auxiliary controller (or deluxe MX controller) connectors for moisture, corrosion, or pins that have pushed back out of their sockets
- Check wire 4330 (or 4110) for continuity and for any short to supply voltage, and check wire 2330 (or 2110) for continuity along its full run
- Wiggle-test the harness and connectors near the front rod solenoid and controller while watching for the fault to reappear, especially if the code has been intermittent
- Inspect the mainframe harness and, where equipped, the deluxe MX power and control harness for chafing, pinch points, or damage that could open the circuit
How the code clears
Cycle power to clear the code once the repair is complete. No separate clearing step is listed beyond cycling the key switch off and back on.

Frequently asked questions
What does Bobcat code H2707 mean?
It means the auxiliary controller (or deluxe MX controller) has detected an open circuit on the front rod solenoid, either on the signal wire or the return wire. The controller responds by disabling the front rod solenoid, which stops hydraulic flow through the front auxiliary male coupler.
What is the panel display number for H2707?
It shows as 27-07 on the numeric panel display.
Will H2707 stop my machine from running?
No. It disables the front rod solenoid function used for front-mounted hydraulic attachments, but it does not describe an effect on core machine operation like driving or engine function.
Which Bobcat machines can show H2707?
It applies to a wide range of models including the E35, E45, S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770.
What wires and components should I check first for H2707?
Start with the front rod solenoid connector and controller connectors for corrosion or pushed-back pins, then check signal wire 4330 (or 4110 on deluxe MX systems) for shorts to supply voltage or opens, and return wire 2330 (or 2110) for opens.
Why does H2707 sometimes come and go?
If the fault is intermittent, the root cause can be hard to pin down on the first check. Loose connections, corrosion, pushed-back pins, the controller, or the harness itself, alone or in combination, are all listed as possible reasons the code may not stay active during testing.
How do I clear H2707 after repairing it?
Cycle power on the machine. No other clearing procedure is listed.
