What is C04D5?

The Diagnostic Trouble Code (DTC) C04D5 is specific to certain vehicles, primarily affecting models like the 2016 to 2020 Ford Explorer, among others. This code indicates a problem within the vehicle's electronic control system, specifically related to the chassis control module. When this error code is triggered, it typically signifies that the system has detected an issue with the vehicle's stability control features, which can compromise handling, traction, and overall safety. Real-world implications of C04D5 include potential malfunctions in features like ABS (Anti-lock Braking System) or traction control, which are crucial for safe driving, especially under adverse conditions. Drivers may notice that their vehicle feels unstable during sharp turns or when accelerating on slippery surfaces. Ignoring this code can lead to further damage and costly repairs down the line. Therefore, it is essential to address the C04D5 code promptly to ensure the safety and reliability of your vehicle.

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

Symptoms

Common symptoms when C04D5 is present:

  • Check engine light stays on constantly, indicating a fault that needs attention.
  • Vehicle stability feels compromised, especially during cornering or acceleration, leading to driver discomfort.
  • Increased stopping distance or ABS warning light activation, which can pose serious safety risks.
  • Unusual noises from the chassis area while driving, suggesting potential component failure.
  • Decreased fuel efficiency, potentially due to the malfunctioning electronic control systems.

Possible Causes

Most common causes of C04D5 (ordered by frequency):

  1. The most common cause of the C04D5 code is a faulty chassis control module, with a likelihood of about 60%. This can occur due to electrical faults or internal component failures.
  2. A second common cause is damaged wiring or poor connections in the chassis control system, which can lead to intermittent faults and is responsible for around 25% of cases.
  3. Another possible cause is software glitches within the vehicle's onboard systems, which can usually be resolved with a software update at the dealership.
  4. Less commonly, faulty sensors related to traction control can trigger this code, leading to safety features becoming ineffective.
  5. In rare cases, water intrusion into the chassis control module due to poor sealing can cause system failures.
