What is C0AE6?
The diagnostic trouble code (DTC) C0AE6 signifies an issue related to the vehicle’s hybrid battery management system, particularly in models such as the 2016-2020 Ford Fusion Hybrid. This code often indicates that the battery control module (BCM) has detected a fault within the hybrid battery system. In practical terms, this means the vehicle might experience issues related to power delivery, fuel efficiency, and overall hybrid performance. When this code triggers, it usually results in the check engine light illuminating on the dashboard. Failing to address this code could lead to diminished fuel efficiency and even potential failure of the hybrid battery system, which can be costly to repair. It’s essential for vehicle owners to understand that this code often points to deeper issues within the electric battery management system, including possible faults in the battery cells or connections. Addressing these issues promptly can prevent more severe damage and higher repair costs in the future.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0AE6 is present:
- The check engine light stays on constantly, signaling a potential hybrid system issue.
- The vehicle may experience unexpected power loss during acceleration, making driving feel unresponsive.
- Fuel economy may decrease by 10-20%, indicating the hybrid system is not functioning efficiently.
- Unusual noises may come from the engine compartment, suggesting electrical or mechanical issues.
- The vehicle's electric-only mode may not engage, limiting the efficiency of hybrid operation.
Possible Causes
Most common causes of C0AE6 (ordered by frequency):
- The most common cause is a failing battery module, which can occur in about 60% of cases. This may be due to age or temperature exposure.
- A second common cause is a faulty battery management system sensor, which may miscommunicate battery health and status, affecting performance.
- A third potential cause is loose or corroded battery connections. Keeping connections clean and tight can prevent issues.
- Less commonly, the battery control module itself may fail, though this is more serious and could require replacement.
- A rare cause is software glitches within the vehicle's control systems, which can sometimes be resolved through software updates.
