Bobcat W3267 (32-67) Fault Code: ACS Operating Mode Switch Flipped While Operating

TL;DR
W3267 sets when the Bobcat ACS (Advanced Control System) controller sees a voltage change on signal wire 4450/4550 after PTOL (Power-To-Loader/attachment control) has been enabled. This usually means the hand/foot mode selection switch was toggled mid-operation, or there is a wiring fault on that signal circuit. Lift and tilt functions are disabled when this code is active.
Medium severity. W3267 does not indicate engine or hydraulic damage risk, but it shuts down lift and tilt functions immediately, which stops loader work until the mode switch state is corrected or the wiring fault is found. Treat it as a stop-and-diagnose issue rather than an emergency, unless it happens while a load is raised, in which case treat it as urgent.
What does Bobcat error code W3267 mean?
W3267 is set by the ACS controller when it detects an unexpected voltage change on signal wire 4450/4550 after PTOL has been enabled. This wire tells the controller whether the machine is in hand mode or foot mode: in hand mode the wire does not carry battery voltage to the ACS controller, and in foot mode it does.
When the controller sees that signal change while PTOL is already active, it assumes the operator mode was switched mid-operation or that the signal circuit is faulty, and it disables the lift and tilt functions as a protective response.
This code is tied specifically to the hand/foot mode selection switch circuit and its wiring, not to the hydraulic pump, valves, or engine. The fault is electrical/logic in nature: a real switch change, a wiring short or open, or a bad connection can all trigger it.
Common causes of W3267
- Operator toggled the hand/foot mode selection switch after PTOL was already enabled.
- Signal wire 4450/4550 shorted to supply voltage, shorted to ground, or open.
- Supply wire 1785 shorted to ground or open.
- Faulty hand/foot selection mode switch.
- Faulty ACS controller.
- Moisture, corrosion, or pushed-back pins in the ACS controller connectors, hand/foot mode selection switch, ACS wire harness, cab harness, or mainframe harness connectors.
- Intermittent fault not present at time of testing: possible loose connections, corrosion, pushed-back pins, the controller itself, the wire harness, or a combination of these.
How to troubleshoot Bobcat W3267: first checks
- Confirm the key switch is on and PTOL is enabled, since these are the conditions required for the code to be active.
- Ask the operator whether the hand/foot mode switch was moved while PTOL was enabled, since this is the simplest and most common cause.
- Inspect the hand/foot mode selection switch and its wiring for damage, looseness, or an obviously stuck or failed switch.
- Check signal wire 4450/4550 for shorts to supply voltage, shorts to ground, or an open circuit.
- Check supply wire 1785 for a short to ground or an open circuit.
- Inspect ACS controller connectors, the hand/foot mode switch connector, and the ACS, cab, and mainframe harness connectors for moisture, corrosion, or pushed-back pins.
- If the code will not reproduce during testing, treat it as intermittent and focus on connections, corrosion, and pushed-back pins across the harness before condemning the controller.
How the code clears
The listed condition for clearing W3267 is simply that PTOL is enabled again. No separate reset procedure or additional step is listed beyond re-enabling PTOL after the underlying wiring or switch fault has been corrected.

Frequently asked questions
What does W3267 mean on a Bobcat loader?
It means the ACS controller detected a voltage change on the hand/foot mode signal wire 4450/4550 after PTOL was already enabled. This is usually caused by the operator flipping the hand/foot mode switch mid-operation or by a fault in that switch's wiring.
Why did my lift and tilt stop working with this code?
Bobcat's ACS controller disables lift and tilt functions automatically whenever W3267 is active, as a protective response to the unexpected mode signal change.
Can I just flip the hand/foot switch back and clear this myself?
If the code was caused by simply toggling the switch while PTOL was enabled, re-enabling PTOL in the correct mode may clear it, since that is the listed condition for clearing the code. If it recurs without switch changes, it points to a wiring or component fault that needs diagnosis.
What wires and components are involved in W3267?
The code centers on signal wire 4450/4550 and supply wire 1785, the hand/foot mode selection switch, the ACS controller, and the connectors on the ACS harness, cab harness, and mainframe harness.
What if the code doesn't show up when the technician checks it?
That means the fault is intermittent. Likely causes include loose connections, corrosion, pushed-back pins, a marginal controller, or the wire harness, alone or in combination, and these should be inspected even without an active fault.
Which Bobcat models can show code W3267?
It appears on S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 models equipped with the ACS controller.
Is W3267 the same as code 32-67?
Yes, 32-67 is the numeric panel display form of the same fault code W3267.
