CaseIH Maxxum115 warning (code?) light

LarrySTN · Jan 21, 2020

I'm not sure where to ask, here or Case or IH, but I've got a warning/stop light showing shortly after starting the engine, any help on diagnosing, reading trouble code, will be greatly appreciated.
Again it's a Case/IH maxxum 115. Thanks Much.

A picture of the symbol would be helpful. The 2 most often seen upon startup are water in fuel & dirty air filter.

Does it look like part of a triangle with an arrow pointing down?

Larry: Don't you just love this new fangled stuff ! lol.

Yes, SETX, it does.

Yes, Mike, it's great, the tractors computer decides to throw a code light.....call the dealer. Too bad ag equipment doesn't fall under the same rules as
over the road vehicles.

code 115, Engine Speed Sensor signal is failed (no signal at engine controller pin A17)

Forget previous comment. Wish we could edit.

Does this 115 use DEF? If so, that could be a engine rpm
Signal saying it?s about to cut rpms. Along with the STOP light.

Add fresh DEF and run it till she clears. If you don?t start these newer tractors with DEF weekly and run at 1000 to 1500 rpm the 3 filters get clogged.

Also, Case IH knows they have a bad batch of DEF tank sensor. Should be covered.

This unit is pre-DEF
