TL;DR
W3240 (panel code 32-40) sets when the ACS controller sees the lift handle or lift pedal signal outside the neutral voltage range while PTOL is enabled. When it sets, lift and tilt functions are disabled until the signal returns to neutral and the fault is cleared.
High severity. Lift and tilt are disabled the moment this code is active, which stops productive work immediately. It is not an engine or structural failure, but it can strand a loader mid-task and points to a real wiring or sensor problem that needs a fix, not a workaround.
What does Bobcat error code W3240 mean?
W3240 is set by the ACS controller (the electronic control system that manages hand or foot control of lift and tilt on these skid steers and track loaders) when it detects that the lift handle or lift pedal signal is not sitting in the neutral voltage range while PTOL is enabled.
The normal neutral range for both the handle signal wire 4650 and the pedal signal wire 4660 is 2.24 to 2.48 volts. If either signal reads outside that window when PTOL is turned on, the controller assumes the handle or pedal is being held out of neutral, or that something in the circuit is faulty, and it shuts down lift and tilt as a precaution.
This is a safety interlock: the machine will not let you run lift or tilt functions if it cannot confirm the control is centered. That protects against unexpected boom or bucket movement on startup or when PTOL is engaged.
Common causes of W3240
- Operator is physically holding the lift handle or pedal out of the neutral position when PTOL is enabled.
- Harness damage anywhere in the ACS wiring between the controller and the handle/pedal sensor.
- Signal wire 4650 shorted to the 5 volt supply voltage (this only affects hand mode).
- Signal wire 4660 shorted to the 5 volt supply voltage (this only affects foot mode).
- Ground wire 2650 or 2660 open.
- A failed handle or pedal sensor.
- A fault in the ACS controller itself.
- Moisture, corrosion, or pushed-back pins in the ACS controller, lift handle connector, lift pedal connector, or ACS harness connectors.
- Intermittent causes that are not present at the time of testing, including loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these.
How to troubleshoot Bobcat W3240: first checks
- Confirm the operator is not resting a hand or foot on the lift handle/pedal when PTOL is enabled; release fully to neutral and see if the code clears.
- With the key switch on and PTOL enabled, check the handle signal wire 4650 and pedal signal wire 4660 for voltage in the 2.24 to 2.48 volt neutral range at the connector.
- Inspect the ACS controller, lift handle connector, lift pedal connector, and harness connectors for moisture, corrosion, or pushed-back pins.
- Check ground wires 2650 and 2660 for continuity to make sure neither circuit is open.
- Look for chafed, pinched, or damaged harness sections between the ACS controller and the handle/pedal sensor, especially near pivot points.
- If the code is intermittent, wiggle-test the harness and connectors while monitoring the signal voltage, since loose connections and pushed-back pins often only show up under movement or vibration.
How the code clears
The listed condition for clearing this code is simply that PTOL is enabled after the repair is complete and the handle/pedal signal reads back in the normal neutral range. No separate reset procedure is listed for this code.

Frequently asked questions
What does W3240 mean on a Bobcat skid steer or track loader?
It means the ACS controller detected that the lift handle or lift pedal signal was not in the neutral voltage range while PTOL was enabled. The controller responds by disabling lift and tilt functions.
What is the normal neutral voltage range for W3240?
Both the handle signal wire 4650 and the pedal signal wire 4660 should read 2.24 to 2.48 volts when the handle or pedal is centered in neutral.
Why are lift and tilt disabled when W3240 sets?
The ACS controller treats an out-of-range neutral signal as a safety condition. Since it cannot confirm the handle or pedal is centered, it locks out lift and tilt to prevent unintended movement.
Can holding the lift handle or pedal cause W3240?
Yes. If the operator is holding the handle or pedal out of neutral when PTOL is enabled, the controller will see the signal outside the neutral range and set the code. Releasing to neutral may resolve it if that was the only cause.
Is W3240 different in hand mode versus foot mode?
Some causes are mode-specific. A short of signal wire 4650 to the 5 volt supply only affects hand mode, while a short of signal wire 4660 to the 5 volt supply only affects foot mode.
How do you clear W3240 once it's fixed?
The condition listed for clearing the code is that PTOL is enabled with the handle/pedal signal back in the normal neutral range. No separate reset procedure beyond that is listed.
What if W3240 comes and goes?
An intermittent W3240 can be harder to pin down. Likely causes include loose connections, corrosion, pushed-back pins, a harness issue, or the controller itself, alone or in combination, and the fault may not be reproducible at the exact moment of testing.
