C1168 DTC Code: Causes, Symptoms, and Potential Solutions

If you own a vehicle and have encountered the C1168 Diagnostic Trouble Code (DTC), you may be wondering what it means and how it can be resolved. This article will provide you with a thorough understanding of the C1168 DTC code, including its causes, symptoms, and potential solutions. So, let’s dive deep into this topic to get a better grasp of what this code entails.

What is the C1168 DTC Code?

The C1168 DTC code is an OBD-II (On-Board Diagnostics) code that indicates a fault in the ABS (Anti-lock Braking System) fluid pressure motor relay circuit. When this code is triggered, it suggests a malfunction in the ABS system, specifically related to the fluid pressure motor relay. The ABS system plays a crucial role in ensuring your safety on the road by preventing wheel lockup during hard braking.

Possible Causes of C1168 DTC Code

Now that we know what the C1168 DTC code represents, let’s explore some of the possible causes behind its occurrence. Understanding the root causes can help in identifying the necessary steps to resolve the issue effectively. Here are a few potential causes:

  1. Faulty ABS Fluid Pressure Motor: A malfunctioning ABS fluid pressure motor can lead to the triggering of the C1168 DTC code. This vital component is responsible for maintaining the appropriate pressure within the braking system.

  2. Electrical Wiring Issues: Problems with the wiring connected to the ABS fluid pressure motor relay can also result in the C1168 DTC code. Loose connections, short circuits, or damaged wiring may disrupt the signal transmission and trigger the code.

  3. Defective ABS Control Module: The ABS control module, which oversees the proper functioning of the entire ABS system, may be defective. A malfunction in this module can lead to the activation of the C1168 DTC code.

Recognizing Symptoms of C1168 DTC Code

Now that we’re familiar with potential causes, it’s important to recognize the symptoms associated with the C1168 DTC code. Identifying these signs can help you mitigate the issue promptly and ensure the safety of your vehicle. Here are some symptoms that may indicate the presence of the C1168 DTC code:

  • Illuminated ABS Warning Light: One of the most noticeable signs of the C1168 DTC code is the illumination of the ABS warning light on your vehicle’s dashboard. This light is specifically designed to alert you of any issues with the ABS system.

  • Decreased Braking Performance: A malfunctioning ABS system may adversely impact your vehicle’s braking performance. If you notice a reduction in braking efficiency or experience unusual braking behavior, it could be a result of the C1168 DTC code.

  • Intermittent ABS System Operation: In some cases, the ABS system may work only intermittently or fail to engage altogether due to the C1168 DTC code. This irregular operation can pose safety risks, especially during emergency braking situations.

How to Resolve the C1168 DTC Code?

Resolving the C1168 DTC code requires proper diagnosis and appropriate actions to rectify the underlying issue. While it’s recommended to consult a professional mechanic for a thorough examination, here are some potential solutions that might address the problem:

  1. ABS Fluid Pressure Motor Replacement: If the ABS fluid pressure motor is determined to be faulty, replacing it with a new one can eliminate the C1168 DTC code. It is crucial to ensure that the replacement motor is compatible with your vehicle’s make and model.

  2. Repairing Electrical Wiring: If the issue lies within the electrical wiring, repairing or replacing faulty wires can resolve the problem. A complete inspection of the wiring system should be conducted to identify any loose connections, damaged insulation, or short circuits.

  3. ABS Control Module Replacement: In the event of a defective ABS control module, replacing it can be an effective solution to eliminate the C1168 DTC code. However, reprogramming or reconfiguring the new module might be necessary for optimal performance.

Frequently Asked Questions (FAQs):

Q: Can I continue driving my vehicle with the C1168 DTC code?

A: It is generally not recommended to continue driving with the C1168 DTC code present. This code indicates a malfunction in the ABS system, which may affect your vehicle’s braking performance and compromise your safety on the road. It is advised to address the issue promptly by seeking professional assistance.

Q: How much does it cost to fix the C1168 DTC code?

A: The cost of resolving the C1168 DTC code may vary depending on factors such as the cause of the issue, the necessary replacement parts, and local labor rates. It is recommended to consult with a trusted mechanic for an accurate estimate based on your specific vehicle and location.

Q: Can I reset the C1168 DTC code on my own?

A: While it is possible to reset the DTC codes using an OBD-II code reader or scanner, it is crucial to understand that merely resetting the code will not fix the underlying problem. The C1168 DTC code is a symptom of an actual issue, and resetting it without addressing the cause may lead to the code recurring shortly after.

In conclusion, the C1168 DTC code signifies a fault in the ABS fluid pressure motor relay circuit. Understanding the potential causes, recognizing the symptoms, and taking appropriate measures to resolve the issue are vital for maintaining the safety and optimal performance of your vehicle. It is highly recommended to consult a professional mechanic for a thorough diagnosis and efficient resolution of the C1168 DTC code.
