What is C0F87?
The diagnostic trouble code (DTC) C0F87 indicates a communication error between the Body Control Module (BCM) and the Powertrain Control Module (PCM). This code is particularly prevalent in 2015-2018 Ford F-150 models and signifies that the BCM has detected a malfunction in the data communication network. The implications of this code are significant, as proper communication between these control modules is crucial for various vehicle functions, including lighting, climate control, and engine operation. When C0F87 is triggered, drivers may experience issues like erratic electrical behavior, malfunctioning lights, or even problems with the engine's performance due to improper signals being transmitted. In essence, this code can lead to a cascade of operational issues that impact the overall functionality of the vehicle. If left unaddressed, the communication error can lead to more severe problems, including potential safety risks while driving. Thus, understanding and addressing the C0F87 code promptly is essential for maintaining your vehicle's reliability and safety on the road.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0F87 is present:
- Check engine light illuminates and remains on, indicating a persistent issue that needs diagnosing.
- Electrical systems malfunction, such as headlights flickering or dashboard lights behaving erratically, which can be distracting and unsafe.
- Vehicle performance issues, including hesitation during acceleration or unexpected stalling, which can create dangerous driving conditions.
- Decreased fuel economy, potentially by 10-15%, due to the engine not receiving accurate information from the sensors.
- Inconsistent climate control operation, where the air conditioning or heating may not respond correctly to adjustments.
Possible Causes
Most common causes of C0F87 (ordered by frequency):
- Faulty wiring or poor connections in the communication network (60% likelihood), which can often be visually inspected for damage or corrosion.
- Defective Body Control Module (BCM) (25% likelihood), which may require replacement if it fails to communicate properly with the PCM.
- Software glitches in the PCM or BCM (10% likelihood), which can sometimes be resolved through software updates.
- Less common but serious cause: Short circuits in the vehicle's wiring harness (3% likelihood), which can lead to severe electrical issues and should be diagnosed immediately.
- Rare cause: A malfunctioning fuse that affects the BCM's operation (2% likelihood), which can be a quick fix if identified.
