Bobcat H2932 (29-32) Fault Code: High Flow Solenoid Over Current

Also shown on the panel as 29-32 · Also called High-Flow Overcurrent

High Flow Solenoid Over Current · ai-assisted, editor-reviewed · Last updated 2026-07-13

TL;DR

H2932 (panel form 29-32) sets when the auxiliary controller senses too much current on return wire 2460 for the high flow solenoid, more than the controller's output driver can safely handle. When it sets, the controller disables the high flow solenoid until the fault is fixed and power is cycled.

Medium severity. The high flow function is shut down until repaired, which limits attachment performance, but the machine itself remains drivable and no engine or hydraulic system damage is described. Treat it as a stop-and-diagnose issue before running attachments that need high flow.

What does Bobcat error code H2932 mean?

H2932 is an overcurrent fault on the high flow solenoid circuit. The auxiliary controller monitors current on return wire 2460, and if that current climbs above what the controller's output driver can safely handle, it trips the fault and shuts the solenoid off to protect its own internal circuitry.

This is a protective response, not necessarily a sign that the solenoid itself is bad. A short between return wire 2460 and either the supply voltage or signal wire 4460 will draw excess current and trip the same fault, as can a failing solenoid coil, a bad auxiliary controller, or corroded/damaged connections anywhere in that circuit.

Because the fault disables the high flow solenoid outright, operators will notice a loss of high flow function on attachments until the code is cleared and the underlying issue is repaired.

Common causes of H2932

  • Return wire 2460 shorted to supply voltage, or shorted to signal wire 4460
  • Faulty high flow solenoid
  • Faulty auxiliary controller
  • Moisture, corrosion, or pushed-back pins in the auxiliary controller connectors, the high flow solenoid connector, or the mainframe harness
  • Intermittent causes that may not show up during testing if the fault isn't active, including loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these

How to troubleshoot Bobcat H2932: first checks

  1. With the key off, inspect the high flow solenoid connector and the auxiliary controller connectors for moisture, corrosion, or pins that have pushed back out of their sockets
  2. Trace return wire 2460 for chafing or contact points where it could short to a supply voltage wire or to signal wire 4460
  3. Check the mainframe harness along its run for pinch points, rubbing, or damage that could cause an internal short
  4. Test the high flow solenoid coil for a short or abnormal resistance if wiring checks out clean
  5. If the code isn't active at the time of testing, treat it as intermittent and recheck all connectors and harness sections for loose or marginal connections rather than assuming the fault cleared itself

How the code clears

Cycle power to clear the code once the repair is complete. There is no separate reset procedure listed beyond turning the key switch off and back on.

Frequently asked questions

What does Bobcat code H2932 mean?

It means the auxiliary controller detected too much current flowing through the high flow solenoid's return wire 2460, more than its output driver can handle safely, so it shut the high flow solenoid off to protect itself.

What is the panel display number for H2932?

On the numeric panel display, H2932 shows as 29-32.

Will my Bobcat still drive with code H2932 active?

Yes, the fault disables the high flow solenoid function specifically. It does not affect basic drive operation, but any attachment relying on high flow won't work correctly until the fault is fixed.

What usually causes H2932?

The most common causes are a short in return wire 2460 (to supply voltage or to signal wire 4460), a bad high flow solenoid, a failing auxiliary controller, or corrosion and damaged pins in the connectors and harness.

How do I clear H2932 after repair?

Cycle the key switch off and back on. That's the only clearing step listed for this code.

Why does H2932 come and go instead of staying on?

Intermittent faults usually point to loose connections, corrosion, or pushed-back pins that only cause a short or open under certain vibration or moisture conditions. If the code isn't active during testing, recheck all connectors and harness sections carefully rather than assuming it's resolved.

Which Bobcat models can show code H2932?

This code applies across the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 models.
