C1113 DTC Code: A Comprehensive Guide


When it comes to troubleshooting vehicle issues, Diagnostic Trouble Codes (DTCs) play a crucial role. These codes help identify specific problems within a vehicle’s systems, aiding mechanics in providing accurate diagnoses and efficient repairs. In this article, we will delve into the details of the C1113 DTC code, exploring its meaning, causes, symptoms, and possible solutions.

Understanding the C1113 DTC Code

The C1113 DTC code refers to a specific fault in the Electric Power Steering (EPS) function of a vehicle. EPS systems, commonly found in modern vehicles, provide assistance to the driver in steering the vehicle. When this DTC code is triggered, it indicates an issue within the EPS system, requiring immediate attention to ensure optimal vehicle performance and safety.

Common Causes of C1113 DTC Code

Several factors can contribute to the occurrence of the C1113 DTC code. It is essential to identify the root cause accurately to determine the appropriate steps for resolving the issue. Here are some common causes of the C1113 DTC code:

  1. Faulty Power Steering Control Module: The power steering control module, responsible for managing the EPS system, can develop internal faults or malfunctions, leading to the triggering of the C1113 DTC code.

  2. Wiring or Connection Problems: Frayed, damaged, or loose wiring within the EPS system can disrupt the communication between various components, resulting in the C1113 DTC code.

  3. EPS Motor Malfunction: The Electric Power Steering motor, which assists in steering control, may experience issues such as motor failure or excessive resistance, leading to the C1113 DTC code.

  4. Sensor Issues: Faulty sensors within the EPS system, including position sensors or torque sensors, can cause the C1113 DTC code to appear.

Symptoms of C1113 DTC Code

When a vehicle displays the C1113 DTC code, it often exhibits specific symptoms that can help identify the underlying issue. Recognizing these symptoms can aid in a faster and more accurate diagnosis. Here are common symptoms associated with the C1113 DTC code:

  • Steering Wheel Hard to Turn: One of the primary signs of a C1113 DTC code is increased resistance when attempting to turn the steering wheel. The steering may feel heavier and require more effort than usual.

  • EPS Malfunction Indicator Lamp: The vehicle’s dashboard will display the EPS malfunction indicator lamp or the power steering warning light when the C1113 DTC code is detected. This serves as a visual cue that an issue exists.

  • Strange Noises: The EPS system may emit unusual noises, such as grinding or whining sounds, when the C1113 DTC code is present. These noises can indicate problems with the motor or other components.

It is crucial to address these symptoms promptly to prevent further damage and ensure safe driving conditions.

Resolving the C1113 DTC Code

Resolving the C1113 DTC code involves a systematic approach aimed at identifying and rectifying the root cause. Depending on the exact problem, repairs may range from simple fixes to component replacements. Here are some potential solutions for addressing the C1113 DTC code:

  1. Diagnostic Scan and Reset: The first step is to perform a diagnostic scan using a suitable scan tool to retrieve the specific DTCs present, including the C1113 code. Once identified, the codes can be reset, and the vehicle can be test-driven to ensure the issue does not reoccur.

  2. Inspect and Repair Wiring: A thorough inspection of the wiring and connectors related to the EPS system is necessary. Look for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring or connectors as needed.

  3. Power Steering Control Module Replacement: If the power steering control module is determined to be the cause of the C1113 DTC code, it may need to be replaced. Ensure the replacement module is compatible with the vehicle’s make and model.

  4. EPS Motor Replacement: If the EPS motor is faulty, replacing it with a new or refurbished unit can resolve the C1113 DTC code. Proper calibration and initialization of the new motor are crucial for optimal performance.

Frequently Asked Questions (FAQs)

  1. Q: Can I continue driving my vehicle with the C1113 DTC code present?

    • A: While it might be physically possible to drive the vehicle with the C1113 DTC code, it is strongly advised against doing so. Continued driving without addressing the issue can lead to further damage and potentially unsafe driving conditions.
  2. Q: Can I clear the C1113 DTC code myself using an OBD-II scanner?

    • A: Yes, you can use an OBD-II scanner to clear the C1113 DTC code. However, it is crucial to identify and rectify the root cause before clearing the code. Simply resetting the code without addressing the underlying issue may result in its immediate reappearance.
  3. Q: How much would a typical repair for the C1113 DTC code cost?

    • A: The cost of repairing the C1113 DTC code can vary depending on factors such as the specific cause, the extent of the problem, and the vehicle’s make and model. It is recommended to consult with a qualified mechanic or service center to obtain an accurate cost estimate.


The C1113 DTC code serves as a powerful diagnostic tool, alerting vehicle owners and mechanics to potential issues within the Electric Power Steering system. Understanding the causes, symptoms, and potential solutions associated with this code is crucial for maintaining vehicle performance and safety on the road. If you encounter the C1113 DTC code, it is advisable to consult a professional mechanic to diagnose and resolve the issue effectively.
