What is C0E73?

DTC C0E73 is a diagnostic trouble code that indicates a malfunction in the vehicle's communication network, specifically related to the control module for the electric parking brake system. This code is commonly found in various models of vehicles, including the 2016-2019 Ford Escape, 2017-2020 Honda CR-V, and some Toyota models. When the C0E73 code triggers, it typically signifies that the vehicle's onboard diagnostic system has detected an issue with the signal between the electric parking brake control module and other related components. For car owners, this can lead to several real-world implications, such as the inability to engage or disengage the parking brake effectively, which can pose safety risks, especially on inclines. Additionally, vehicles may exhibit a warning light on the dashboard, prompting immediate attention. Ignoring this code can lead to further complications, such as complete failure of the electric parking brake system, which may require more expensive repairs down the line. Regular diagnostics using tools like the GeekOBD APP can help monitor and address these issues promptly, ensuring your vehicle operates safely and efficiently.
