Next time, Dozer catches the code when it fires.
Plug a CAN logger into the machine's J1939 port, or connect the telematics you have. When a code fires, Dozer opens a repair ticket with the meaning, how urgent it is and what to check.
- The code, the machine and its hours on one ticket
- Severity sorted: keep working, plan a stop, or stop now

Questions crews ask
What does SPN 1110 mean?
The engine protection system shut the engine down.
Can I keep running with SPN 1110?
Stop the machine. Shut it down where it's safe and find the cause before you run it again. If the machine derates or the stop lamp is on, stop.
What should I check first for SPN 1110?
Don't keep restarting it. Find the code that caused it (oil pressure, coolant temp, coolant level) and fix that first.
How do I clear SPN 1110?
Fix the cause first. Most codes go inactive by themselves once the condition is gone and the engine has run a key cycle or two. Clearing it with a service tool without a fix only hides it until it comes back.
Which machines show SPN 1110?
Any diesel that speaks SAE J1939: excavators, dozers, loaders, haul trucks, generators and on-road trucks with Cat, Cummins, Deere, Komatsu, Volvo, Kubota, Perkins and other engines. The SPN means the same thing on all of them; the fix steps can differ, so check the service manual.
