What is C07C5?

DTC C07C5 refers to a specific communication error within the vehicle's electronic control unit (ECU), particularly concerning the steering angle sensor or the steering column control module. This code is prevalent in models like the 2015-2018 Chevrolet Silverado and GMC Sierra 1500. When you see this code, it means that there's an issue with how the vehicle's systems communicate regarding steering inputs. In simpler terms, the car may not be able to correctly interpret the driver's steering commands, potentially leading to erratic handling or a loss of power steering assistance. This can make driving more challenging and, in some cases, unsafe. If ignored, it could lead to further complications such as increased wear on the steering components and other related systems. It's crucial to address this code promptly to ensure safe vehicle operation. The problem may stem from wiring issues, sensor failures, or software glitches, and should be diagnosed by a qualified technician. Regular checks and maintenance can help in preventing such issues, ensuring that your vehicle remains reliable and safe on the road.

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

Symptoms

Common symptoms when C07C5 is present:

  • The check engine light remains illuminated, indicating a potential issue with the vehicle's steering system.
  • Drivers may experience steering wheel stiffness or resistance, making it difficult to maneuver the vehicle, especially at low speeds.
  • There may be noticeable fluctuations in power steering assistance, leading to inconsistent handling during turns or lane changes.
  • The steering angle sensor may provide incorrect readings, resulting in unexpected vehicle behavior such as drifting or wandering.
  • In some cases, the vehicle's traction control system may be disabled, increasing the risk of loss of control in slippery conditions.

Possible Causes

Most common causes of C07C5 (ordered by frequency):

  1. The most common cause is a faulty steering angle sensor, which accounts for about 60% of cases. This sensor can fail due to wear or electrical issues, leading to incorrect steering input readings.
  2. Another common cause is damaged wiring or connectors in the steering column. These issues can occur due to wear and tear or environmental factors, and they can disrupt communication between the sensor and the ECU.
  3. Software glitches in the steering control module can also trigger the C07C5 code. Regular software updates and diagnostics can help prevent these problems.
  4. Less frequently, a malfunctioning power steering pump may cause symptoms similar to this code, but this is a less common source of the issue.
  5. Rarely, issues with the vehicle's main ECU or other related control modules can lead to communication errors, potentially requiring more extensive diagnosis and repair.
