What is C0C49?
DTC C0C49 is a diagnostic trouble code that indicates a malfunction in the vehicle's battery management system, specifically related to the control module's communication with the battery monitoring sensor. This code typically appears in vehicles equipped with advanced energy management systems, such as the 2015-2018 Ford F-150. When this code is triggered, it may suggest that the battery is not being monitored correctly, which can lead to various issues, including poor battery performance, unexpected vehicle shutdowns, or difficulty starting the engine. It’s crucial to address this issue promptly, as it could lead to more extensive electrical problems if left unresolved. Drivers may notice that their vehicle's electrical components, like lights and infotainment systems, may function erratically. Furthermore, a vehicle experiencing this code might have reduced fuel efficiency due to the battery not being optimally managed, leading to unnecessary power draw from the engine. Overall, understanding the implications of DTC C0C49 can help car owners take timely action, ultimately ensuring their vehicle remains reliable and safe on the road.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0C49 is present:
- Check engine light stays on constantly, indicating an issue with the vehicle's battery system.
