Bobcat W3264 (32-64) Fault Code: ACS Pedal Lock Short to Battery
Also shown on the panel as 32-64 · Also called ACS (AHC) Pedal Lock Short to Battery

TL;DR
W3264 (panel display 32-64) sets when the Bobcat ACS controller sees voltage on the pedal lock signal wire 4260 when that signal was not commanded. It points to a short to battery on wire 4260, a bad hand/foot mode selection switch, an ACS controller fault, or a corroded/damaged connector somewhere between the ACS, cab, and mainframe harnesses.
Medium severity. W3264 itself does not describe a runaway or shutdown condition, but the pedal lock system affects control input on foot pedal operation. Treat it as a diagnose-this-shift issue rather than an emergency, unless pedal lock behavior is acting unpredictably in the seat, in which case stop and investigate before continuing work.
What does Bobcat error code W3264 mean?
W3264 (also seen as M3264 on some displays) is set by the ACS controller when it detects voltage present on signal wire 4260, the pedal lock feedback line, at a time when the controller has not commanded that voltage. Normally, the ACS controller supplies battery voltage to the pedal locks on signal wires 4270 and 4280, and to the hand/foot control mode switch LED on signal wire 4275, only when foot mode is selected and PTOL is enabled.
In plain terms, the controller expects wire 4260 to be quiet unless it just told the pedal lock circuit to energize. If that wire shows voltage on its own, the controller assumes a short to battery voltage somewhere in that circuit and logs the fault to protect the pedal lock function from acting on bad information.
Common causes of W3264
- Signal wire 4260 shorted to supply voltage
- Hand/foot mode selection switch fault
- ACS controller fault
- Moisture, corrosion, or pushed back pins in the ACS harness, cab harness, mainframe harness, or pedal lock connectors
- Intermittent conditions where the code is not active at the time of testing, possibly from loose connections, corrosion, pushed back pins, the controller, the wire harness, or a combination of these problems
How to troubleshoot Bobcat W3264: first checks
- With key switch in run/enter position, pull up the active and stored code list to confirm W3264 is present and check whether it is active or historical/intermittent
- Inspect the ACS, cab, and mainframe harness connectors near the pedal lock circuit for moisture, corrosion, or pins that have pushed back out of their connector body
- Trace signal wire 4260 for chafe points or damage that could allow contact with a battery-voltage wire, since a short to supply voltage on this wire is the first listed cause
- Test the hand/foot mode selection switch for proper operation, since a faulty switch is a listed cause
- Check ACS controller connections and grounds before condemning the controller itself
- If the code will not stay active for testing, wiggle-test the harness and connectors along the ACS, cab, and mainframe runs to try to reproduce an intermittent short
How the code clears
Clearing conditions require PTOL to be enabled after the repair is complete. No separate reset procedure is listed for this code beyond enabling PTOL once the underlying wiring, switch, or controller issue is corrected.

Frequently asked questions
What does W3264 mean on a Bobcat machine?
It means the ACS controller detected voltage on the pedal lock signal wire 4260 when it had not commanded that voltage, which normally points to a short to battery voltage in that circuit, a bad hand/foot mode switch, a controller fault, or corrosion/pin damage in the ACS, cab, or mainframe harness connectors.
Is W3264 the same as M3264?
Yes, the underlying description is identical. Some Bobcat displays and technical documents reference this fault as M3264 while the panel numeric code and this article use W3264 (32-64 on the panel).
What sets the conditions for this code?
The code is checked whenever the key switch is in the run/enter position. Beyond that, no separate voltage, time, or temperature threshold is listed for when the controller declares the fault active.
Can this code be intermittent?
Yes. If the fault is not active at the time of testing, the cause may not be found immediately. Likely intermittent causes include loose connections, corrosion, pushed back pins, the controller itself, or the wire harness, or a combination of these problems.
What has to happen for the code to clear?
PTOL must be enabled after the repair is completed. No other reset step is documented for this fault.
Which Bobcat models can show W3264?
This code applies across a range of Bobcat skid steer and compact track loader models including S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770, as well as T870.
Should I keep operating the machine with W3264 active?
Since this affects the pedal lock circuit tied to hand/foot control mode switching, it is best to diagnose it before continued operation if you notice any unexpected pedal lock behavior. If pedal lock function seems normal, it can typically be diagnosed within the shift rather than treated as an emergency stop.
