Code P1489 on a Chrysler 300M indicates a problem with the cooling fan relay circuit. This code typically means that the engine control module (ECM) has detected an issue with the operation of the cooling fans, which could be due to a faulty relay, wiring issues, or a malfunctioning fan motor. Addressing this code usually involves inspecting the relay, wiring, and the fans themselves to ensure proper operation.
