Defect temperature sensor
(reference 1image 5-34) which
measures the temperature at the
secondary side of the SMPS.
Replace the temperature sensor.
Code 7701: “Power supply secondary temp short” (Error)
Situation
Solution
Damaged wire unit of the
temperature sensor (reference
1 image 5-34 and image 5-33).
Repair or replace the wire unit.
Defect temperature sensor
(reference 1 image 5-34) which
measures the temperature at
heatsink of the secondary side of the
SMPS.
Replace the temperature sensor mounted on the heatsink of the secondary side of the
SMPS (reference 1image 5-34).
Code 7702: “Power supply primary DCDC temp low” (Error)
