Disconnect the thermal sensor harness from connector CN5 on the cooler board.
2.
Measure the resistance between cables 511 and 512 in socket connector 5XS5
disconnected from CN5. The resistance should vary according to the table below
depending on the measured temperature from the thermal sensor.
If the measurement specification is
not
met, replace the thermal sensor.
