Code U05AA Dodge Description
The Auxiliary Coolant Pump is a smart device that contains a LIN Bus communication module and a coolant pump. To maintain a desired charge air temperature, the PCM sends a pump speed command over the LIN bus to the internal Auxiliary Coolant Pump. The internal Auxiliary Coolant Pump module controls the pump speed/coolant flow rate using Pulse-Width Modulation (PWM). The Auxiliary Coolant Pump assembly monitors for internal system circuit and performance failures. If a fault occurs the Auxiliary Coolant Pump module sends the fault information to the PCM through the dedicated LIN Bus. The PCM processes the information received, then sets the correlating fault.
