Open array " scanner not responding "

HI,
I have a M92654-S 4kw open array radar. I receive a warning alert on my display
"Scanner not responding"
I verified good 12 volt power at the radar pedestal array unit. (12.38 volts)
I ran an ohms test with results below.

Video pins 1&2 white and black wires reading 45.9 kohms

Azimuth pins 12&13 violet/purple and gray reading 9.38 kohms

Trigger pins 4&7 orange and yellow reading 9.39 kohms

Data I/O pins 6&10 green and blue reading 182.8 to 183.2 ohms

I verified the readings with 2 multi meters. Are these considered good connections?
I measured readings at plug display cable end and at scanner connection inside pedestal.
Is there something else I should look for to remove the display warning?
Thanks in advance,
Dan
