Description
The main Drive Interface (DI) is limiting torque to other drive units while one drive unit is engaged in spindown learning calibration routine, which selects either drive unit rotor learning (rotor flux and/or rotor offset) or resolver learning (error table) routines.
Potential Impact
Only the drive unit engaged in spindown learning calibration responds to torque requests, limiting torque available from other drive units and power while driving.
Set Condition
A drive unit reports it has entered spindown learning calibration state to the main Drive Interface (DI) while the vehicle is in Service Mode.
Clear Condition
Spindown learning calibration routine completes and vehicle enters Neutral (N).
