Bobcat M1307 (13-07) Fault Code: Fuel Shutoff Hold Coil Open Circuit
Also shown on the panel as 13-07 · Also called Fuel Hold Solenoid Open Circuit

TL;DR
M1307 sets when the gateway controller detects an open on the fuel shutoff solenoid hold wire (wire 8800, or 8150/8800, or 33410/8800 depending on model). It only displays at startup. If it occurs during operation, the engine shuts off and the code will not display until the key is cycled. The starter is disabled while this code is active.
High severity. This code disables the starter and can shut the engine off during operation without warning until power is cycled, so the machine should not be put back into service until the fuel shutoff solenoid circuit is repaired.
What does Bobcat error code M1307 mean?
M1307 means the gateway controller has detected an open circuit on the fuel shutoff solenoid hold wire, which on different Bobcat models is labeled wire 8800, wire 8150/8800, or wire 33410/8800. The fuel shutoff solenoid is what allows fuel flow to the engine when the key is turned on. If the hold circuit that keeps the solenoid energized goes open, the controller cannot confirm the solenoid is holding correctly.
This code is unusual in when it shows up. It will only be displayed at startup. If the open condition happens while the machine is running, the engine will shut off immediately, but the M1307 code itself will not appear on the display until the operator cycles the key power off and back on.
Whenever M1307 is active, the starter is disabled. This is a built-in safety and functional lockout tied directly to the fuel shutoff circuit fault, meaning the machine cannot be restarted until the condition is addressed or at least until power has been cycled and the fault is not currently present.
Common causes of M1307
- Fuel shutoff solenoid not connected to the harness.
- Wire 8800 (or 8150/8800, or 33410/8800 depending on model) shorted to supply voltage or open.
- Faulty fuel shutoff solenoid.
- Faulty gateway controller.
- Moisture, corrosion, or pushed-back pins in the gateway controller connectors, fuel shutoff solenoid connector, or the mainframe wire harness.
- Intermittent fault: if the code is not active at the time of testing, the root cause may not be found immediately. Probable causes for intermittent codes include loose connections, corrosion, pushed-back pins, the controller itself, the wire harness, or a combination of these problems.
How to troubleshoot Bobcat M1307: first checks
- Confirm the key switch is in the run/enter position, since this is the condition required for the code to set.
- Inspect the fuel shutoff solenoid connector to verify it is fully seated and connected.
- Visually inspect the fuel shutoff solenoid hold wire (8800, 8150/8800, or 33410/8800 depending on model) for chafing, breaks, or a short to supply voltage.
- Check the gateway controller connectors and the mainframe wire harness connectors for moisture, corrosion, or pins that have been pushed back out of their sockets.
- Test the fuel shutoff solenoid itself for proper operation if the wiring and connectors check out.
- If the code is not currently active, treat it as intermittent and recheck all connections, since the cause may not be reproducible during a single test session.
How the code clears
Clearing M1307 requires cycling power (turning the key off and back on) after the repair is complete. Because this code only displays at startup, if the fault occurs mid-operation the engine will shut off but the code will not show until the next power cycle, so always cycle the key after any repair to confirm the code does not return.

Frequently asked questions
What does Bobcat code M1307 mean?
It means the gateway controller found an open circuit on the fuel shutoff solenoid hold wire. Depending on the model this wire is labeled 8800, 8150/8800, or 33410/8800. The code only shows on the display at startup.
Why did my Bobcat shut off with no code showing?
If the fuel shutoff solenoid hold wire opens while the machine is running, the engine shuts off immediately but M1307 will not display until you cycle the key power off and back on.
Why won't my Bobcat start after this code?
M1307 disables the starter as part of its fault response. The starter will stay disabled until the open circuit condition is resolved or no longer present after a power cycle.
What wire is involved in M1307?
Depending on the model, the fuel shutoff solenoid hold wire is labeled 8800, 8150/8800, or 33410/8800. Check for it shorted to supply voltage or open.
How do I clear code M1307 after repair?
Cycle power by turning the key off and back on. No other separate clearing procedure is listed for this code.
Can M1307 be an intermittent problem?
Yes. If the code is not active when you test, the cause may not be found right away. Likely causes for intermittent versions include loose connections, corrosion, pushed-back pins, the controller, or the wire harness, or a combination of these.
Which Bobcat models can show code M1307?
M1307 applies to the S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870 models.
