What is C1472?
The diagnostic trouble code (DTC) C1472 refers to a fault in the vehicle's body control module (BCM), specifically indicating a communication issue between the BCM and other control modules. This code is most commonly found in vehicles like the 2015-2020 Ford F-150, but may appear in various models across the Ford lineup. When the C1472 code is triggered, it often results from a failure in the wiring harness, poor connections, or a malfunctioning BCM. This can lead to various electrical issues, such as problems with power windows, locks, or even the vehicle's lighting systems. In real-world terms, this could mean that you may experience intermittent functionality in features that rely on the BCM, potentially affecting your overall driving experience. Ignoring this code can lead to further complications, including complete failure of electronic components or systems that rely on the BCM, which could be both inconvenient and costly to repair. Therefore, understanding and addressing the C1472 code promptly is crucial for maintaining the reliability and safety of your vehicle.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1472 is present:
- The check engine light remains illuminated continuously, indicating a persistent issue that needs attention.
- Power windows may operate intermittently, leading to frustration when trying to adjust them.
- The vehicle's locking system might malfunction, causing doors to lock or unlock unexpectedly, which can compromise security.
- Dashboard warning lights may flicker or fail to illuminate properly, impacting the driver’s awareness of vehicle status.
- Electrical accessories such as headlights or interior lights may behave erratically, affecting visibility and safety.
Possible Causes
Most common causes of C1472 (ordered by frequency):
- The most common cause of the C1472 code is a faulty body control module (BCM), which occurs in about 40% of cases. This can happen due to manufacturing defects or wear over time.
- A second common cause is damaged wiring or poor connections in the wiring harness, accounting for around 35% of issues. Exposure to moisture or abrasion can lead to corrosion and eventual failure.
- A third possible cause is software issues within the BCM, which can occur in approximately 15% of cases. Regular updates and diagnostic checks can help mitigate this risk.
- Less common but serious causes include short circuits in other electronic components, which can lead to widespread failures and significant repair costs.
- A rare cause could be interference from aftermarket electronic devices, which may disrupt the normal operation of the BCM.
