What is C0C4A?

The DTC C0C4A trouble code indicates a problem related to the control module in certain vehicles, particularly seen in models like the 2016-2020 Ford F-150 and other Ford vehicles. This code means that the vehicle’s diagnostic system has detected an issue with the 'Chassis Control Module' or a related circuit. When this code is triggered, it often leads to various symptoms such as warning lights on the dashboard, potential loss of vehicle functions, or even a decrease in overall performance. The C0C4A code can arise from several factors, ranging from wiring issues and faulty modules to software glitches. If left unaddressed, this code can lead to more significant issues like erratic electrical behavior or failure of vehicle systems, which could potentially compromise safety. Therefore, it’s crucial for vehicle owners to understand this code and take immediate action to diagnose and resolve the underlying problems. Regular scans using tools like the GeekOBD APP can help catch this code early, allowing for timely repairs and maintenance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0C4A is present:

  • Check engine light illuminates or flashes consistently, indicating an issue that requires attention.
  • Loss of power assist in steering or brakes, making the vehicle more challenging to control in certain conditions.
  • Erratic behavior of electrical components, such as windows or locks, which may work intermittently or fail completely.
  • Decreased fuel efficiency, possibly due to the vehicle running less efficiently when the module is malfunctioning.
  • Unusual noises or vibrations during operation, which could signal deeper issues with the vehicle's control system.

Possible Causes

Most common causes of C0C4A (ordered by frequency):

  1. Faulty Chassis Control Module (CCM) - Approximately 40% likelihood; this module may fail due to moisture ingress or electrical faults.
  2. Wiring issues or bad connections - About 30% of cases; damaged wiring can disrupt signals to and from the control module.
  3. Software glitches - Roughly 20%; outdated software may lead to communication failures between modules.
  4. Corrosion in connectors or terminals - 10%, can lead to intermittent faults.
  5. Less common but serious - Short circuits or damaged sensors, which could lead to significant repair needs.
