What is C0E90?
DTC C0E90 is a diagnostic trouble code that typically indicates a problem with the vehicle's network communication, often associated with a malfunction in the Body Control Module (BCM) or a related system. This code is particularly common in 2015-2018 Ford F-150 trucks but can also appear in other vehicles with similar electronic systems. When your vehicle's onboard computer detects a failure in communication between modules, it triggers the C0E90 code, signaling that there's a disruption in how these systems interact. This can lead to a variety of symptoms, including irregularities in lighting, issues with power windows, or even problems starting the engine. Ignoring this code can lead to more severe electrical system failures over time, making it crucial to address. Drivers may notice that certain electrical components are not functioning as expected, which can significantly impact the vehicle's overall operation and safety. To properly diagnose this code, a comprehensive inspection of the vehicle's electrical connections, software updates, and module integrity is essential.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0E90 is present:
- The check engine light remains illuminated, indicating a persistent issue that requires attention.
- Drivers may experience intermittent failures of electrical components, such as power windows that operate erratically.
- Reduced functionality in dashboard indicators, making it difficult to read vehicle performance metrics accurately.
- Unusual noises from the vehicle's electrical system, such as clicking or buzzing, which can signal deeper issues.
- The vehicle may have difficulty starting, especially after prolonged inactivity, indicating potential BCM or battery issues.
Possible Causes
Most common causes of C0E90 (ordered by frequency):
- The most common cause is a faulty Body Control Module (BCM), accounting for approximately 60% of C0E90 occurrences. This module manages various electrical functions, and its failure can disrupt communication.
- Another common cause is damaged wiring or connectors, which can lead to poor electrical connections and signal loss. Inspecting the wiring harness for frays or corrosion is essential.
- Software issues, including outdated firmware in the BCM, can also cause communication failures. Regular software updates can prevent this problem.
- Less common but serious issues include short circuits in the electrical system, which can lead to significant damage if not addressed promptly.
- A rare cause might be a faulty ignition switch, which can prevent proper power distribution to the vehicle's electrical systems.
