Bobcat A8332 (83-32) Fault Code: ACD/RACD Output “D” Over Current
Also shown on the panel as 83-32 · Also called ACD Output ‘D’ Overcurrent

TL;DR
Bobcat code A8332 (panel display 83-32) means the ACD/RACD controller has detected too much current flowing through the Output "D" solenoid circuit, at return wire controller pin J1 A-27, and has shut that output off to protect the driver. This affects attachment control on many Bobcat skid steer, track loader, and excavator models.
Medium severity. Output "D" is disabled when this code sets, so whatever attachment function runs on that output will stop working. It is not an immediate safety emergency, but you should not keep cycling the function or forcing the controller until the short or bad component is found, since repeated overcurrent events can damage the controller's output driver.
What does Bobcat error code A8332 mean?
A8332 is set by the ACD/RACD controller, the module that manages Advanced Control of the attachment (ACD) or Remote/Reverse Advanced Control of Attachments (RACD) functions on the machine. The controller drives several solenoid outputs to control attachment functions, and Output "D" is one of them.
This code means the controller measured more current flowing through the Output "D" solenoid circuit, specifically through the return wire at controller pin J1 A-27, than the internal output driver is rated to handle safely. To protect itself from damage, the controller disables Output "D" as soon as it detects the overcurrent condition.
In practical terms, whatever attachment function is wired to Output "D" will stop responding until the underlying electrical problem is found and fixed.
Common causes of A8332
- Return wire at controller pin J1 A-27 shorted to supply voltage, or shorted to the Output "D" wire at controller pin J1 B-25
- A failed or shorted Output "D" 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 "D" solenoid connector
- An intermittent condition, in which loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these can cause the code to set even though it is not present at the time of testing
How to troubleshoot Bobcat A8332: first checks
- With the key switch / Run-Enter position on, check for the active code and note whether it is currently present or was only stored as intermittent
- Inspect the Output "D" solenoid connector and the ACD/RACD controller connectors for moisture, corrosion, or pins that have pushed back out of their sockets
- Trace the return wire from controller pin J1 A-27 and check it for a short to supply voltage or a short to the Output "D" wire at controller pin J1 B-25
- Inspect the mainframe harness and attachment control harness along the run to the Output "D" solenoid for chafed, pinched, or damaged wiring
- Test the Output "D" solenoid itself for an internal short or failure
- If no fault is found and the code is not currently active, treat it as intermittent and recheck all connectors and harness sections for loose connections or corrosion before suspecting the controller
How the code clears
Once the repair is complete, clear the code by cycling power (turn the key switch off, then back on). No separate reset procedure or step-by-step clearing sequence is listed beyond cycling power.

Frequently asked questions
What does Bobcat code A8332 mean?
It means the ACD/RACD controller detected excessive current through the Output "D" solenoid circuit, at the return wire on controller pin J1 A-27, and disabled that output to protect itself from damage.
Which Bobcat machines can show code A8332?
It can appear on Bobcat E35, E42, E45, E55, S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770 models, among others equipped with the ACD/RACD controller.
Will my attachment still work with code A8332 active?
The specific function wired to Output "D" will not work, since the controller disables that output as soon as it detects the overcurrent fault. Other attachment functions on different outputs should still operate normally.
How do I clear code A8332 after fixing the problem?
Cycle power by turning the key switch off and back on. That is the only clearing step listed for this code.
What is controller pin J1 A-27 on my Bobcat?
It is the return wire pin for the Output "D" solenoid circuit on the ACD/RACD controller's J1 connector. A short from this pin to supply voltage or to the Output "D" wire at pin J1 B-25 is a listed cause of A8332.
Why does A8332 come and go instead of staying on?
Intermittent overcurrent faults are often caused by loose connections, corrosion, or pushed-back pins in the connectors or harness that only cause a short under certain conditions, such as vibration or moisture. If the code is not active when you test, you may need to wiggle-test connectors and harness sections to find the intermittent fault.
Is code A8332 dangerous to keep operating with?
It is not listed as an immediate safety hazard, but continuing to operate with an active overcurrent condition risks further damage to the ACD/RACD controller's output driver. It is best to diagnose and repair the short before relying on that attachment function again.
