What is C0D97?

The Diagnostic Trouble Code (DTC) C0D97 typically indicates a fault within the vehicle's electronic systems, particularly related to communication issues with the control modules. This code is often encountered in models like the 2015-2020 Ford F-150, where it suggests discrepancies in data exchange between different modules such as the Powertrain Control Module (PCM) and Body Control Module (BCM). When a vehicle throws a C0D97 code, it can lead to various operational issues, including erratic behavior of vehicle systems, failure of certain functionalities, or even complete system shutdown in extreme cases. Car owners may notice symptoms like the engine light illuminating, malfunctioning electrical components, or unexpected vehicle handling. Ignoring this code can lead to further complications, making it essential for drivers to address it promptly to ensure vehicle safety and performance.

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

Symptoms

Common symptoms when C0D97 is present:

  • The check engine light stays on constantly, signaling a persistent issue that needs addressing.
  • Engine hesitates during acceleration, making the vehicle feel sluggish and unresponsive.
  • Fuel economy decreased by 10-15%, indicating possible inefficiencies in the engine management system.
  • Electrical accessories like power windows or locks may malfunction intermittently, causing inconvenience.
  • Strange warning messages appear on the dashboard, often linked to various vehicle systems.

Possible Causes

Most common causes of C0D97 (ordered by frequency):

  1. The most common cause is a faulty wiring harness or connection issue, which can occur in about 60% of cases. This can lead to signal loss between modules.
  2. A software glitch in the control module accounts for about 20% of cases. This can often be resolved with a software update from the manufacturer.
  3. Corrosion at terminal connections can cause communication failures, and preventive measures include regular inspections and cleaning.
  4. Less common but serious causes include failure of the BCM or PCM, which can lead to significant repair costs and downtime.
  5. Rarely, interference from aftermarket accessories can affect module communication, which can be avoided by ensuring compatibility.
