TL;DR
Bobcat fault code A8007 (panel display 80-07) sets when the ACD/RACD controller cannot detect the solenoid wired to output "A", controller pin J1 B-5, or its return wire, controller pin J1 A-2. When it sets, output "A" is disabled until the open circuit is fixed and power is cycled.
Medium severity. Output "A" is disabled once this code sets, which can shut down whatever attachment function relies on that output. It is not an engine-damage or immediate safety-shutdown code, but the attachment function tied to output "A" will not work until it is fixed.
What does Bobcat error code A8007 mean?
A8007 is set by the Attachment Control Device / Remote Attachment Control Device (ACD/RACD) controller on Bobcat skid steers, compact track loaders, and compact excavators. This controller manages powered attachments through dedicated outputs, and output "A" is one of those solenoid driver circuits.
The controller expects to see a solenoid load connected across output "A" (controller pin J1 B-5) and its return path (controller pin J1 A-2). If that loop is open, no current path exists, and the controller cannot confirm the solenoid is present. It responds by disabling output "A" and setting A8007 so the operator knows that attachment function is no longer being driven.
This is fundamentally a wiring and connection fault code. It points to a break somewhere between the controller and the solenoid, at the solenoid itself, or occasionally inside the controller.
Common causes of A8007
- Output "A" wire, controller pin J1 B-5, or the return wire, controller pin J1 A-2, open (broken, disconnected, or cut circuit).
- Faulty output "A" solenoid (bad coil or internal open).
- Faulty ACD/RACD controller.
- Moisture, corrosion, or pushed-back pins in the ACD/RACD controller connectors, mainframe harness, attachment control harness, or the output "A" solenoid connector.
- Intermittent fault: if the code is not active at the time of testing, the cause may not be found immediately. Probable underlying causes in this case include loose connections, corrosion, pushed-back pins, the controller itself, the wire harness, or a combination of these problems.
How to troubleshoot Bobcat A8007: first checks
- With the key switch / (run/enter) on, check that the code is active before chasing wiring, since some cases are intermittent and may not repeat on demand.
- Inspect the ACD/RACD controller connectors, mainframe harness connectors, and attachment control harness connectors for moisture, corrosion, or pins that have pushed back out of their sockets.
- Visually and physically inspect the output "A" solenoid and its connector for damage, corrosion, or a loose connection.
- Check continuity on the output "A" circuit, controller pin J1 B-5, and the return wire, controller pin J1 A-2, looking for an open circuit anywhere along the harness.
- If wiring and the solenoid check out, test the solenoid coil itself for an open winding, then consider the ACD/RACD controller as a possible cause if everything else is good.
How the code clears
Cycle power (turn the key switch off and back on) after the repair is complete. No other reset procedure is listed for this code.

Frequently asked questions
What does Bobcat code A8007 mean?
It means the ACD/RACD controller could not detect the solenoid on output "A" because the circuit through controller pin J1 B-5 or the return wire at pin J1 A-2 is open. Output "A" gets disabled until the fault is fixed.
What is the panel display number for A8007?
On the display it shows as 80-07.
Will my attachment stop working with this code?
Yes. Once A8007 sets, output "A" is disabled, so whatever attachment function is wired to that output will not operate until the open circuit is repaired.
What usually causes A8007?
The most common causes are an open wire on output "A" or its return, a bad output "A" solenoid, or corrosion, moisture, or pushed-back pins in the connectors. Less often, the ACD/RACD controller itself is at fault.
The code isn't showing right now, does that mean it's fixed?
Not necessarily. This code can be intermittent. If it is not active during testing, the cause may still be present, commonly loose connections, corrosion, pushed-back pins, harness damage, or the controller.
How do I clear A8007 after repairing it?
Cycle power by turning the key switch off and back on. No other clearing procedure is listed.
Which machines can show code A8007?
It applies across Bobcat models equipped with ACD/RACD controllers, including the E35, E42, E45, E55 excavators, S510 through S770 skid steers, and T550 through T870 compact track loaders.
