Bobcat H2432 (24-32) Fault Code: Rear Rod Solenoid Over Current
Also shown on the panel as 24-32 · Also called Rear Rod Output Overcurrent
Rear Rod Solenoid Over Current · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
H2432 sets when the auxiliary controller detects too much current through the rear rod solenoid return wire 2430, more than the output driver can safely handle. This solenoid controls hydraulic flow to the rear auxiliary male coupler, and once the fault sets, the controller disables that solenoid until the problem is fixed and power is cycled.
Medium severity. The affected solenoid is disabled once the code sets, which cuts off rear auxiliary hydraulic flow to whatever attachment is plugged into the rear male coupler. This will stop attachment function but does not by itself threaten the engine or main drive systems, so it is safe to diagnose within the shift rather than an emergency shutdown.
What does Bobcat error code H2432 mean?
Code H2432, shown as 24-32 on the panel display, is set by the auxiliary controller when it senses excessive current draw through the rear rod solenoid's return wire, identified as wire 2430. This solenoid is the component that directs hydraulic flow to the rear auxiliary male coupler, which is how many attachments receive hydraulic power at the back of the machine.
The controller's output driver is only rated to handle so much current before it risks damage. When the draw on wire 2430 exceeds that safe limit, the controller shuts the rear rod solenoid off entirely to protect itself, rather than letting the driver overheat or fail. That means any attachment function relying on that solenoid will stop working until the fault is cleared.
This code applies across the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 skid-steer and compact track loader models.
Common causes of H2432
- Return wire 2430 shorted to supply voltage, or shorted to signal wire 4430
- A failed rear rod solenoid
- A fault in the auxiliary controller itself
- Moisture, corrosion, or pushed-back pins in the auxiliary controller connectors, the rear rod solenoid connector, or the mainframe harness
- Loose connections in the wiring or connectors, or a combination of these harness problems
- If the code is intermittent and not present at the time of testing, the root cause may not be identifiable right away
How to troubleshoot Bobcat H2432: first checks
- With the key switch off, inspect the rear rod solenoid connector and the auxiliary controller connectors for moisture, corrosion, or pins that have been pushed back out of position
- Trace wire 2430 for any signs of chafing, pinching, or contact with bare metal that could cause a short to supply voltage or to signal wire 4430
- Check the mainframe harness along its run for damage, loose connections, or corrosion, especially near pivot points and connector junctions
- Inspect the rear rod solenoid itself for physical damage or signs of internal failure
- If the fault will not reproduce during testing, wiggle-test the harness and connectors near the rear rod solenoid and auxiliary controller while watching for the code to reappear, since intermittent faults often trace back to loose or corroded connections
How the code clears
Cycle the key switch power off and back on after completing repairs. No separate clearing step is listed beyond this power cycle, and the code requires the key switch or run/enter switch to be on for it to set in the first place.

Frequently asked questions
What does Bobcat code H2432 mean?
It means the auxiliary controller detected too much current flowing through the rear rod solenoid return wire, wire 2430, more than the controller's output driver can safely handle. The controller responds by disabling the rear rod solenoid to protect itself.
What is the panel display number for H2432?
On the display panel, H2432 shows as 24-32.
Will my rear attachment stop working with this code?
Yes. Once H2432 sets, the rear rod solenoid is disabled, which affects hydraulic flow through the rear auxiliary male coupler. Attachments relying on that flow path will not function correctly until the fault is fixed.
What usually causes H2432?
Common causes include wire 2430 shorted to supply voltage or to signal wire 4430, a failed rear rod solenoid, a fault in the auxiliary controller, or moisture, corrosion, and pushed-back pins in the related connectors and mainframe harness.
How do I clear H2432 after fixing the problem?
Cycle the key switch power off and back on. That is the only clearing step listed for this code.
Why does this code come and go instead of staying on?
Intermittent H2432 codes are usually tied to loose connections, corrosion, or pushed-back pins that make and break contact. If the fault isn't present when you test, you may need to wiggle-test the harness and connectors to reproduce it.
Which Bobcat models can show code H2432?
H2432 applies to the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 models.
