Hyster H16XMS-12:
ERROR E1921

Hi!

We recently change the DPF filter to our forklift Hyster H16XMS-12 because this part was damage and need to be replace, but after the change, the instrument display show the Error E1921.

I search in the "Cummins Engine Fault Code Guide" and found the error: Aftertreatment Particulate Filter Differential Pressure - Data Valid But Above Normal Operating Range - Moderately Severe Level

What do you recommend us to do to fix this error? I appreciate any help you can give us.
