Check these first

• A failing drive motor B
• Wiring problems between the motor and the power electronics
• A power electronics module fault
• A high voltage battery with low state of charge or cell imbalance

What to do next

1. Read drive motor B phase W current on a scan tool
2. Inspect the phase W wiring to the power electronics
3. Check the high voltage battery state of charge and cell balance
4. Test the power electronics module
5. Replace the module if phase W output is wrong
6. Clear the code and retest
