Is there E11 error?
Yes
Machine is turned off.
1) Resistance value is measured between
the 3rd and 4th pins of the KN1 socket which
has been removed from the card. Resistance
value is approx. 1.5 Ohm. There should not
be open circuit or short circuit
2)Again, the resistance value is measured
between pin 1 and pin 2 ends of the KN1
socket and there should not be any open
Are both measurement
values correct?
