Bobcat M1407 (14-07) Fault Code: Fuel Pull Output Open Circuit
Also shown on the panel as 14-07 · Also called Fuel Pull Solenoid Open Circuit
Fuel Pull Output Open Circuit · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
M1407 (panel code 14-07) sets when the Bobcat gateway controller detects an open circuit on the fuel pull output, wire 8110. This wire energizes the fuel pull relay. When M1407 is active, the starter is disabled and the machine will not crank.
High severity. M1407 disables the starter, so the machine cannot be cranked or started until the open circuit is found and repaired. It is not an emergency shutdown of a running engine, but it stops work immediately and needs to be fixed before the machine can be put back into service.
What does Bobcat error code M1407 mean?
: M1407 is set by the gateway controller when it sees an open circuit on wire 8110, the fuel pull output. This wire's job is to energize the fuel pull relay, which is part of the circuit that controls fuel delivery for starting and running the engine.
Because the fuel pull relay circuit is tied into the starting sequence, Bobcat's control logic disables the starter whenever this code is active. In practical terms, that means an operator turning the key will not get a crank until the wiring fault is corrected and the fault is addressed.
This code covers two closely related descriptions, 'Fuel Pull Output Open Circuit' and 'Fuel Pull Solenoid Open Circuit', both pointing to the same wire 8110 open-circuit condition detected by the gateway controller.
What triggers a Bobcat M1407 code?
The code sets when the key switch (run/enter) is on and the gateway controller detects an open circuit on the fuel pull output, wire 8110.
Common causes of M1407
- Fuel pull output wire 8110 shorted to supply voltage or open
- Ground wire open (wire 2035 on some models, wire 2016 on others depending on machine configuration)
- Faulty fuel pull relay
- Faulty gateway controller
- Moisture, corrosion, or pushed-back pins in the gateway controller connector, fuel pull relay connector, or mainframe harness
- Intermittent fault not present at time of testing, which may stem from loose connections, corrosion, pushed-back pins, the controller, the wire harness, or a combination of these problems
How to troubleshoot Bobcat M1407: first checks
- : With the key switch (run/enter) on, check for the code and confirm it is active before disturbing any wiring, since an intermittent fault may not be present at the time of testing.
- Inspect the gateway controller connector and the fuel pull relay connector for moisture, corrosion, or pins that have pushed back out of the connector body.
- Visually trace wire 8110 from the gateway controller to the fuel pull relay, looking for chafing, pinching, or damage that could cause a short to supply voltage or an open circuit.
- Check the relevant ground wire (2035 or 2016 depending on the machine) for continuity and a clean, tight connection at its ground point.
- Test the fuel pull relay itself for proper operation, since a failed relay can mimic an open circuit condition on the output wire.
- Inspect the mainframe harness for damage, corrosion, or loose connectors along the run between the controller and the relay.
How the code clears
Once the repair is complete, cycle power (turn the key switch off and back on) to clear the code. No separate reset procedure is listed for this code beyond cycling power.

Frequently asked questions
What does Bobcat code M1407 mean?
It means the gateway controller detected an open circuit on the fuel pull output, wire 8110, which normally energizes the fuel pull relay. This is described as either 'Fuel Pull Output Open Circuit' or 'Fuel Pull Solenoid Open Circuit' depending on the manual version.
Why won't my Bobcat start when M1407 is active?
Bobcat's control logic disables the starter whenever code M1407 is set, so the machine will not crank until the open circuit is repaired.
What is the panel display number for M1407?
The numeric panel form is 14-07.
What usually causes M1407 on a Bobcat skid steer or track loader?
Common causes include wire 8110 shorted to supply voltage or open, an open ground wire (2035 or 2016 depending on the model), a faulty fuel pull relay, a faulty gateway controller, or moisture and corrosion in the connectors involved.
How do I clear code M1407 after making a repair?
Cycle power by turning the key switch off and back on. No other clearing step is listed.
Which Bobcat models can show code M1407?
This code applies to S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, and T770, and T870 skid steer and compact track loaders.
What if the code doesn't show up when I test the machine?
If M1407 is intermittent and not active during testing, the exact cause may not be identifiable at that time. Likely culprits still include loose connections, corrosion, pushed-back pins, the controller, or the wire harness.
