Bobcat M2402 (24-02) Fault Code: Fuel Pull Relay Error On
Also shown on the panel as 24-02
Fuel Pull Relay Error On · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
M2402 (panel display 24-02) sets when the gateway controller sees voltage on the fuel pull relay feedback wire (3410 or 8150, depending on model) for 5 seconds while the relay is not commanded on. This points to a wiring short, a stuck relay, or a controller/connector problem in the fuel pull circuit.
Medium severity. M2402 does not by itself stop the engine, but the fuel pull relay controls fuel shutoff. Leaving a suspected short or stuck relay unaddressed can affect the machine's ability to shut off fuel properly or can indicate a wiring fault that may worsen. Diagnose it within the shift rather than ignoring it.
What does Bobcat error code M2402 mean?
M2402 is set by the gateway controller when it detects voltage on the fuel pull relay feedback wire, either wire 3410 or wire 8150 depending on the model, for 5 seconds while the relay has not been commanded on.
The fuel pull relay's job is to send battery voltage to the fuel pull solenoid over wire 8100/8120 whenever it is commanded, and at the same time it sends battery voltage to a feedback wire (3410 or 8150) so the gateway controller can confirm the relay actually switched. If the controller sees that feedback voltage show up on its own, without having commanded the relay, it flags M2402.
In plain terms: the controller expects to see the feedback signal only when it tells the relay to turn on. If that signal appears unexpectedly, something downstream is feeding voltage into a circuit that should be off, or a relay or controller is not behaving as commanded.
What triggers a Bobcat M2402 code?
The code sets when the gateway controller detects voltage on the fuel pull relay feedback wire (3410 or 8150) for 5 seconds while the relay is not commanded on, with the key switch (run/enter) on.
Common causes of M2402
- Fuel pull solenoid wire 8100/8120, or the feedback wire (3410 or 8150), shorted to supply voltage.
- A faulty fuel pull relay that is stuck or switching without being commanded.
- A fault in the gateway controller itself.
- Moisture, corrosion, or pushed-back pins in the gateway controller connectors, fuel pull relay connectors, or the mainframe harness.
- Intermittent causes that may not be found if the code is not active at the time of testing, including loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these problems.
How to troubleshoot Bobcat M2402: first checks
- With the key switch on and the fault active if possible, check wire 8100/8120 and the feedback wire (3410 or 8150) for a short to supply voltage using a wiring diagram for the specific model.
- Inspect the gateway controller connectors and the fuel pull relay connectors for moisture, corrosion, or pushed-back pins.
- Inspect the mainframe harness along the fuel pull relay circuit for chafing, pinched wire, or contact with a voltage source.
- Test or swap the fuel pull relay to rule out an internally stuck or shorted relay.
- If the code is not currently active, wiggle-test connectors and harness sections while watching for the code to reset, since intermittent faults may not show up on a static check.

Frequently asked questions
What does Bobcat code M2402 mean?
It means the gateway controller detected voltage on the fuel pull relay feedback wire (3410 or 8150) for 5 seconds when the relay was not commanded on. It points to a wiring short, relay problem, or controller/connector fault in the fuel pull circuit.
Is M2402 the same as panel code 24-02?
Yes. 24-02 is the numeric panel display form of fault code M2402 on the affected Bobcat machines.
Which Bobcat machines can show M2402?
S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 models can display this code.
Can I keep operating with M2402 active?
The code itself does not describe an automatic shutdown, but since it involves the fuel pull relay circuit, it should be diagnosed within the shift rather than run indefinitely, especially if it is intermittent and hard to catch.
Why does my M2402 code come and go?
Intermittent M2402 codes are often caused by loose connections, corrosion, or pushed-back pins that only cause a short or open under certain conditions like vibration or moisture. If the code is not active during testing, the cause may not be found right away.
How do I clear M2402 after repair?
Cycle the key power off and back on. No other clearing procedure is listed for this code.
What is the difference between the 3410 and 8150 feedback wire versions of this code?
Some models route the fuel pull relay feedback signal on wire 3410, others on wire 8150. The logic and causes for M2402 are the same either way, only the specific wire number differs by model.
