Bobcat A8532 (85-32) Fault Code: ACD/RACD Output “F” Over Current

TL;DR
Bobcat fault code A8532, shown on some panels as 85-32, sets when the ACD/RACD controller senses too much current through the output "F" solenoid return wire at controller pin J1 B-18. When it sets, the controller shuts off output "F" to protect its driver circuit.
Medium severity. Output "F" is disabled until the fault clears, which can stop a specific attachment function, but it does not by itself threaten engine or operator safety. Treat it as a diagnose-this-shift issue rather than a stop-work emergency, unless the disabled function is one you need for safe operation.
What does Bobcat error code A8532 mean?
A8532 is set by the Advanced Control of the Device / Remote ACD controller that manages attachment outputs on many Bobcat skid steer, compact track, and excavator platforms. It watches the current flowing through each solenoid output circuit, and output "F" is one of those monitored circuits.
When the controller sees more current on the output "F" return wire, at controller pin J1 B-18, than its internal driver can safely handle, it trips a protective shutdown for that output. This is the same kind of protection you'd expect from a fuse or breaker: it's there to stop the driver circuit inside the controller from being damaged by excess current.
Once A8532 sets, output "F" stops working. Depending on the machine and attachment wired to that output, this could mean an attachment function tied to solenoid "F" no longer responds, even though the rest of the machine keeps running normally.
Common causes of A8532
- Return wire at controller pin J1 B-18 shorted to supply voltage, or shorted to output "F" at controller pin J1 B-19
- A failed or shorted output "F" solenoid
- A fault inside the ACD/RACD controller itself
- Moisture, corrosion, or pushed-back pins in the ACD/RACD controller connectors, mainframe harness, attachment control harness, or the output "F" solenoid connector
- An intermittent condition (loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these) that may not be present or found at the time of testing
How to troubleshoot Bobcat A8532: first checks
- Confirm the key switch is in the run/enter position, since that is the condition required for the controller to set this code, then check whether A8532 is currently active or stored as history
- Inspect the output "F" solenoid connector and the ACD/RACD controller connectors for moisture, corrosion, bent, or pushed-back pins
- Trace the return wire from controller pin J1 B-18 and check for a short to supply voltage or a short to the output "F" wire at pin J1 B-19
- Inspect the mainframe harness and attachment control harness along their length for chafed, pinched, or damaged wiring near the output "F" circuit
- Check the output "F" solenoid itself for an internal short before assuming the controller is at fault
- If the code will not stay active during testing, treat it as intermittent and focus on connections, corrosion, and pushed-back pins across the whole circuit rather than a single component
How the code clears
Once the repair is complete, cycle power to the machine (turn the key switch off, then back on) to clear code A8532. No separate reset procedure or software step is listed for this code.

Frequently asked questions
What does Bobcat code A8532 mean?
It means the ACD/RACD controller detected too much current on the output "F" solenoid return circuit at controller pin J1 B-18, more than the controller's output driver can safely handle, so it disabled output "F" to protect itself.
Which Bobcat machines can show code A8532?
It applies to a range of Bobcat compact excavators and skid steer/track loaders, including E35, E42, E45, E55, S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770 and T870 models, wherever they use an ACD/RACD attachment controller.
Will A8532 stop my machine from running?
No, the base machine should continue to operate. The code disables output "F" specifically, so whatever attachment function or solenoid runs on that output will stop working until the fault is fixed and power is cycled.
What usually causes A8532?
Common causes include a shorted return wire at pin J1 B-18 (either to supply voltage or to the output "F" wire at pin J1 B-19), a failed output "F" solenoid, a fault in the ACD/RACD controller, or moisture and corrosion in the related connectors and harnesses.
How do I clear code A8532 after repair?
Cycle power to the machine, key off and back on, once the underlying wiring, solenoid, or controller issue is repaired. No other reset step is listed.
Why does A8532 come and go instead of staying on?
An intermittent A8532 usually points to loose connections, corrosion, or pushed-back pins that only cause a short under certain vibration, moisture, or connector movement. If the code is not active during testing, check the whole circuit, connectors, harness, solenoid, and controller, rather than assuming one part is the cause.
Can I keep working with A8532 active?
You can generally keep operating the base machine, but the attachment function on output "F" will not work until the fault is cleared. Whether that is safe to work around depends on which function is affected, so check what that output controls on your machine before continuing.
