What vehicles are most commonly affected by C0EAB?
C0EAB is frequently seen in models such as the 2015-2019 Ford Escape and the 2016-2018 Lincoln MKC, among others. Be sure to check for any recalls related to the EPS system.
How can I prevent C0EAB from happening again?
Regular maintenance checks and keeping an eye on steering fluid levels can help prevent C0EAB. Ensuring that your vehicle's electrical system is in good health is also crucial.
What is C0EAB?
The C0EAB diagnostic trouble code (DTC) typically indicates an issue with the vehicle's electric power steering (EPS) system, specifically related to communication errors within the EPS control unit. This code can arise in various vehicle makes and models, particularly in certain Ford and Lincoln vehicles from the late 2010s to early 2020s. When C0EAB is triggered, it suggests that the EPS control module is not receiving or sending data as expected, which can lead to a range of performance issues. Drivers may experience steering difficulty, a lack of power assist, or even complete loss of steering assist. This code often pairs with other related codes, which can give further insight into the underlying issue. In practical terms, if you see C0EAB, it's crucial to address it promptly to avoid potential safety hazards while driving. Ignoring it may lead to increased wear on steering components and could result in a costly repair if not diagnosed early. Proper diagnostics and timely repairs are essential to ensure your vehicle's steering system is functioning correctly and safely.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0EAB is present:
- The check engine light or power steering warning light remains lit on the dashboard, indicating a potential steering issue that requires attention.
- Heavy steering or difficulty in turning the steering wheel, often noticed during low-speed maneuvers, which can make driving stressful and tiring.
- Unusual noises from the steering column or electric power steering pump, such as grinding or whining sounds, which may indicate internal component failure.
- Intermittent loss of power steering assistance, where the steering feels normal at times but suddenly becomes very heavy during certain driving conditions.
- Erratic steering response, where the vehicle does not respond as expected to steering input, which can compromise driving safety.
Possible Causes
Most common causes of C0EAB (ordered by frequency):
- The most common cause of code C0EAB is a faulty electric power steering control module, which has a likelihood of around 60%. This module can fail due to electrical shorts or physical damage.
- Another frequent cause is wiring issues, such as frayed or corroded wires in the EPS system. This problem can occur from exposure to moisture or from wear and tear over time.
- A third potential cause is low power steering fluid levels, which can lead to overheating of the EPS system. Regular maintenance checks can help prevent this issue.
- Less common causes include software glitches in the EPS control module, which can sometimes be resolved with a simple software update from a dealership.
- A rare but serious cause of C0EAB can be a complete failure of the electric power steering pump, necessitating a full replacement of the steering system.
