Caterpillar NRDR30:
Code ED

Hi Folks,
I was blocking and chaining the mast for a hyd hose replacement.
Code Ed showed up.
It will not clear with a key recycle. Operator states it`s been doing that
off and on for a while, always cleared with a key recycle.
Inspected connectors and tested wire harness between display and VM,
No opens or shorts, terminals look OK.
This one is 2GL01577, they have another, 2GL01744.
I`d like to swap parts but the Service Manual note says replacing the
display requires special procedures, contact Material Handling Associates.

Can I swap the display or VM for diagnostics without causing issues?

Thank you
