P2D26Coolant Pump E Control Circuit Performance/Stuck Off

P2D26 indicates that the engine control module (ECM) has detected a performance fault in the electrical control circuit for the engine coolant pump, specifically that the pump is stuck off or not responding as commanded. The ECM monitors the circuit for expected current draw or feedback when the pump is activated, and when the signal does not match the commanded state, it sets this code and may illuminate the check engine light.
