Recently had to take the jeep in to be serviced for Motor Electronics Coolant Pump 'B' Control Performance code (POC74) that set off my check engine light.
Was determined by Jeep engineers that although the dealership diagnostic came back showing the pump seemed to be working, being this was the second time light came on and having warranty coverage the pump was ordered and replaced.

More specific information on this code found here:
