Drive Motor A Coolant Pump Control Circuit Range/Performance

Where it lives

For P0CC2, the description names the pump as the part involved.

Check these first

• A starter/generator coolant pump that is not moving coolant as commanded
• A coolant pump that runs at the wrong speed
• Air trapped in the starter/generator cooling system
• A failed starter/generator control module

What to do next

1. Command the starter/generator coolant pump on with a scan tool
2. Watch starter/generator coolant temperature change with the pump on
3. Check the cooling system for trapped air and low coolant
4. Test the coolant pump control circuit for open and short faults
5. Replace the coolant pump if temperature change stays out of range
6. Clear the code and retest
