Fault 64: M/G Temperature Sensor Failure

InfoCenter Display:
Fault Description
Temperature sensor failures were detected within the motor/generator controller.
Circuit Description
There are 3 separate temperature sensors located inside the motor/generator. They are:
•
Field effect transistor (FET) temperature
•
Motor temperature
•
Logic board temperature
Conditions for Setting the Fault
If the FET and motor temperature sensors fail, this fault is reported.
Recommended Service Actions
Step 1: Verify that the fault repeats.
1. Clear the system faults from the InfoCenter. Refer to
2. Operate the machine.
Pass The fault did not repeat. Go to
Note:
