CUSTOMER CONCERN The check-engine light is on with DTCs U019F, P26D0, and P26CA for the electric engine-coolant pump communication and power circuits. CAUSE The gray power wire in the electric coolant-pump harness was rubbed through by a pump mounting bolt approximately six inches from the connector, leaving the circuit open. CORRECTION Repair the damaged gray electric coolant-pump power wire, secure the harness away from the mounting bolt, clear DTCs U019F, P26D0, and P26CA,

CUSTOMER CONCERN The electric engine coolant pump runs continuously and DTCs U019F and P26CA reset in the PCM. CAUSE The electric coolant-pump connector wiring had a circuit fault, preventing normal communication and pump shutdown control. CORRECTION Repair the electric engine coolant-pump connector wiring, clear DTCs U019F and P26CA, and verify commanded pump speed, shutdown, and cooling-system operation.
