Low Temperature EM
â–¶ How to fix
Ensure that no SC or a beginning of a SC in the cables for the EM temp sensor
What you'll see
No driver-visible symptom recorded.
System reaction
Max allowed AC current is reduced linearly.
Diagnostic depth
Detection
Evaluation Condition When sensor is connected and not short circuit. Set Condition Event is set if motor temperature is below predefined level. Limits: Event is set at MotorLowWarningLevel deg celcius where reduction of AC current starts. At MotorReductionEndLowLevel °C AC current is reduced to 0. If MotorReductionEndLowLevel is 0 reduction is in-active. Clear Condition Event is cleared if motor temperature is above predefined level.
Possible cause
Cold EM. Intermittent SC in temperature sensor or cables.
