Di450 C13FA code

[krm]

I'm thinking the print head is failing. Code comes and goes. I reset all connectors to pwb-b and removed the thumb screws securing PH. Does any one remember the LD1 - LD2 adjustments for this code? Do you lower or higher the values? Will this or other solution rectify this code? Or is the PH needing replacement?
Thanks for your input.

Service bulletin says to lower both LD1 and 2 by 10

Thank you Darren! I could not remember and the service manual is lacking on explaining this adjustment. It is worth a try before replacing the PH. That thing is pricey.
Thanks.
