I have a 2015 hyster 280HD2 with a check engine light. This forklift has a cummins engine and I was told it should have a odb port. I researched manual and used the key switch to try to obtain codes ,however the screen says clear and okclr. I am unable to get any codes. I have taken off the fuse box panel and no port plug or wires for me to plug in a scanner. we do have a new snap on scanner with the cummings software installed. Just no luck trying to get a code to see what is wrong. The forklift came in 2 quarts low I added oil , the oil gauge still blinks when engine light is on.the operator's manual mentioned abut the needle has to be in the middle if too high or low it will have a code. I changed the filter and needle is still a little off from center. 285 hours the forklift has, and oil was changed 35 hours ago.
