Warm EM
Investigate why Electric machine is warm. Look for bad connections in the cables/connectors for the temperature sensor
What you'll see
Linear reduction of propulsion torque from MGS starts at 160degC and ends at 180degC
System reaction
Max allowed AC current is reduced linearly. Yellow OBD
Diagnostic depth
Evaluation Condition When sensor is connected and not short circuit. Set Condition Set if motor temperature is above predefined level. Limits: Event is set at MotorHighWarningLevel deg celcius where reduction of AC current starts. At MotorReductionEndHighLevel °C AC current is reduced to 0. If MotorReductionEndHighLevel is 0 reduction is in-active. Clear Condition Cleared if motor temperature is below MotorHighWarningLevel-1 °C.
Too low coolant flow (externally or internally caused) Too high coolant temperature Heated by surrounding Motor temperature sensor failure Internal hardware failure Wrong look-up table for sensor is used
