TL;DR
Bobcat fault code W3260 (panel display 32-60) sets when the ACS controller commands the tilt actuator to move one way but detects it moving the opposite way during the first tilt movement after startup. When this code sets, both lift and tilt functions are disabled until the fault is cleared and power is cycled.
High severity. Lift and tilt are disabled the moment this code sets, which stops loader work entirely. It is not a runaway or crash-risk fault, but it is a hard functional stop, so it needs prompt diagnosis rather than emergency shutdown.
What does Bobcat error code W3260 mean?
W3260 is set by the Advanced Control System (ACS) controller when it commands the tilt actuator to move in one direction but the actuator's own feedback shows movement in the opposite direction. This check only happens on the first tilt movement after startup, so the controller is essentially confirming the actuator responds correctly before trusting it for the rest of the work session.
Because tilt and lift control the attachment and loader arms, Bobcat disables both functions any time this mismatch is detected. That is a built-in safety measure: if the controller cannot verify that tilt is moving the direction it is told to, it will not risk lift or tilt operating incorrectly with an attachment or load on the arms.
The root cause is almost always wiring or connection related rather than a software problem: reversed motor wires, reversed 5-volt supply and ground wires, a bad actuator, a bad controller, or corrosion and pushed-back pins in the connectors.
Common causes of W3260
- Any active fault code already logged against the tilt actuator can itself cause W3260 to set at the next startup, so an unrelated tilt actuator fault may be the real starting point.
- Tilt actuator motor wires reversed at the connector (documented pairs include 4780/4640 and 4790/4650, or on some harnesses 4780 and 4790 swapped with each other).
- 5-volt sensor supply wire and ground wire reversed (documented pairs include 1630/5990 for supply and 2770/2990 for ground, or 1630 and 2770 swapped on other harnesses).
- A failed tilt actuator itself.
- A failed ACS controller.
- Moisture, corrosion, or pushed-back pins inside the ACS controller connectors, the tilt actuator connector, or anywhere in the ACS wiring harness.
- An intermittent fault that is not present at the time of testing. In that case the cause may be loose connections, corrosion, pushed-back pins, the controller, the harness, or some combination of these, and it may not be pinpointed on the first inspection.
How to troubleshoot Bobcat W3260: first checks
- Confirm the key switch is on, PTOL (pilot operated tilt/lift lockout) is enabled, and a tilt command was actually given, since these are the conditions the controller needs to even run this check.
- Check for any other active or stored codes tied to the tilt actuator first. If one exists, resolve that fault before chasing W3260, since it can trigger this code on its own at startup.
- Inspect the tilt actuator motor wire connectors for correct pinning. Verify the motor wire pairs are not swapped or crossed, using the wire numbers for your harness variant.
- Check the 5-volt supply wire and its ground wire at the actuator and controller connectors to confirm they are not reversed with each other.
- Visually inspect the ACS controller connectors, the tilt actuator connector, and the harness in between for moisture intrusion, green or white corrosion, and pins that look pushed back out of the connector body rather than fully seated.
- If the code is not currently active, treat it as intermittent: wiggle-test harness connectors and check for loose crimps, since the fault may not reproduce on demand.
- If wiring, pins, and connectors all check out, suspect the tilt actuator or the ACS controller itself and test or swap as needed.
How the code clears
Cycle key power off and back on after the wiring or component repair is complete. No separate reset procedure or scan tool clearing step is listed beyond cycling power.

Frequently asked questions
What does Bobcat code W3260 mean?
It means the ACS controller told the tilt actuator to move one direction during the first tilt movement after startup, but detected the actuator actually moving the opposite direction. Both lift and tilt are disabled when this happens.
Why did lift stop working along with tilt?
Bobcat disables both lift and tilt together whenever W3260 sets, even though the fault is specifically about tilt actuator direction. This is intentional so the machine does not operate the loader arms with an unverified tilt actuator response.
Will this code clear itself?
No. Once the wiring, connector, actuator, or controller issue causing the mismatch is repaired, you need to cycle the key switch off and back on. No other reset procedure is listed for this code.
Could this be caused by a completely different fault?
Yes. Any active code already logged against the tilt actuator can trigger W3260 at the next startup on its own, so check for other stored tilt actuator codes before assuming the wiring or actuator itself has failed.
What if the code won't show up again when I test it?
That is common with this fault. If it is intermittent and not active during testing, the likely causes are loose connections, corrosion, pushed-back pins, the controller, or the harness, alone or in combination, and the exact cause may not be identifiable until it happens again.
How is W3260 different from W3265 or W3266?
W3265 and W3266 are about voltage levels: sensor supply voltage or battery voltage being out of range. W3260 has nothing to do with voltage range, it is about the tilt actuator physically moving the wrong direction from what was commanded. If you are chasing a voltage-out-of-range symptom instead of a wrong-direction movement, you want the W3265 or W3266 page, not this one.
Which Bobcat models can show W3260?
It applies to ACS-equipped models including S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870.
