What is C0E92?
The diagnostic trouble code (DTC) C0E92 indicates a communication error between the vehicle's Body Control Module (BCM) and other modules, most commonly seen in vehicles like the 2015-2020 Ford F-150. This code typically arises when the BCM fails to receive or send data correctly, leading to a variety of electrical issues that can affect the vehicle's performance and functionality. For example, you might experience problems with your vehicle's lights, door locks, or other electrical components since the BCM manages these systems. If you're seeing the C0E92 code, it can manifest as a warning light on your dashboard, indicating that there's an issue. Ignoring this code can lead to further complications such as malfunctioning accessories or safety features, making it crucial to address it promptly. The implications can be real-world and immediate, as a malfunctioning BCM can compromise your vehicle's security features, affecting your overall driving experience and safety. Therefore, understanding the implications of the C0E92 code is essential for keeping your vehicle in optimal condition.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0E92 is present:
- The check engine light remains illuminated, signaling a need for diagnostics.
- Electrical components, such as power windows or locks, may become unresponsive or work intermittently.
- You may notice unusual behavior in dashboard lights, such as flickering or failing to illuminate correctly.
- The vehicle may experience difficulty starting, potentially due to BCM communication failures.
- Inconsistent operation of safety features like airbags or traction control can occur.
Possible Causes
Most common causes of C0E92 (ordered by frequency):
- The most common cause of C0E92 is a faulty Body Control Module (BCM), which accounts for about 60% of cases. This could be due to manufacturing defects or wear and tear over time.
- Another frequent cause is damaged wiring or connectors within the BCM circuit, which may lead to poor communication between modules.
- Corrosion at connection points can also trigger this code, especially in older vehicles subjected to harsh weather conditions. Regular inspections can help prevent this.
- Less common, but serious, could be a failure in related modules that communicate with the BCM, leading to widespread issues that require more extensive diagnostics.
- A rare cause might be software glitches within the BCM that necessitate a firmware update to rectify.

Diagnostic Steps
Professional C0E92 Diagnosis Process
Follow these systematic steps to accurately diagnose C0E92. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform an initial visual inspection of the BCM and its wiring for any visible damage or corrosion (5-10 minutes)
Step 1: Perform an initial visual inspection of the BCM and its wiring for any visible damage or corrosion (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to run a full OBD2 scan to retrieve all codes and any freeze frame data to understand the context of the fault (10-15 minutes)
Step 2: Use the GeekOBD APP to run a full OBD2 scan to retrieve all codes and any freeze frame data to understand the context of the fault (10-15 minutes).
Step 3: Step 3: Conduct component testing on the BCM and associated wiring using a multimeter to check for continuity and proper voltage (20-30 minutes)
Step 3: Conduct component testing on the BCM and associated wiring using a multimeter to check for continuity and proper voltage (20-30 minutes).
Step 4: Step 4: After potential repairs, run a system function test to verify proper operation of the BCM and clear any stored codes (10-15 minutes)
