High Speed EM
â–¶ How to fix
Investigate why the EM is achieving high speeds
What you'll see
Linear reduction of propulsion torque from MGS starts at 3400rpm and ends at 3500rpm.
System reaction
Max allowed accelerating AC current is reduced linearly. Yellow OBD
Diagnostic depth
Detection
Evaluation Condition When a valid speed signal is available. Set Condition Uses first order low-pass filtered speed (same as ActualSpeed). Speed is above ModeratelyHighSpeedStartLevel. Clear Condition Uses first order low-pass filtered speed (same as ActualSpeed). Speed is below ModeratelyHighSpeedStartLevel.
Possible cause
Speed limits are set too low for the application Shaft speed is increased externally
