What is U0573?
The Diagnostic Trouble Code (DTC) U0573 indicates a communication error between different modules in the vehicle, particularly within the control systems. This code is triggered when a control module receives an invalid message from another module. For instance, in many vehicles like the 2015-2020 Ford F-150, this can lead to performance issues, as various systems depend on accurate information from each other. A common scenario is when the transmission control module (TCM) fails to communicate effectively with the engine control module (ECM), which can affect engine performance, fuel efficiency, and even safety features like traction control. Drivers may notice symptoms like the check engine light illuminating, erratic shifting, or even loss of power in some cases. Ignoring this code can lead to more severe issues, including potential damage to the transmission or engine components, which can escalate repair costs significantly. Therefore, it’s crucial to address the U0573 code promptly to ensure the vehicle operates smoothly and safely.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0573 is present:
- Check engine light stays on constantly, indicating a persistent issue that requires attention.
- Erratic shifting occurs during acceleration, which may feel like the transmission is slipping or switching gears unexpectedly.
- Fuel economy decreased by 10-15%, leading to increased operating costs as the vehicle struggles to manage fuel efficiency.
- Dashboard warning lights may illuminate, including stability control or traction control alerts, indicating potential safety feature malfunctions.
- Unresponsive or delayed throttle response when accelerating, which could pose safety risks in busy driving conditions.
Possible Causes
Most common causes of U0573 (ordered by frequency):
- The most common cause is a faulty control module connection or wiring issue, occurring in about 40% of cases. This often involves corroded or loose connectors that disrupt communication.
- Another likely cause is software glitches within the control modules, which can result from improper updates or failures during module programming.
- A third cause could be low voltage or weak battery connections affecting the performance of control modules. Regular battery maintenance can prevent this.
- Less common but serious causes include module failure due to overheating or physical damage, which can lead to expensive repairs.
- A rare cause could be electromagnetic interference from aftermarket accessories, which can disrupt signals between modules.
