Common Questions

What does C017C mean and how does it affect my car?

The C017C code signifies a malfunction in the wheel speed sensor circuit, which is crucial for the proper functioning of your vehicle's ABS. If this code appears, it can lead to compromised braking performance, especially in emergency situations, and may require immediate attention to ensure your safety while driving.

What are the most common causes of C017C and how much does it cost to fix?

Common causes of the C017C code include a faulty wheel speed sensor, damaged wiring, or issues with the ABS control module. Repair costs can vary widely, with sensor replacement typically ranging from $150 to $300, while ABS module replacements can be upwards of $600.

Can I drive my car with C017C or should I stop immediately?

It's not advisable to drive your vehicle with the C017C code active, as it indicates potential issues with your braking system. Continuing to drive can lead to decreased braking effectiveness, increasing the risk of accidents. It's best to have it diagnosed and repaired as soon as possible.

How can I diagnose C017C myself using GeekOBD APP?

To diagnose the C017C code using the GeekOBD APP, start by performing an OBD2 scan to identify the code and any freeze frame data. Next, check the live data for the wheel speed sensor readings to see if they are consistent. You can also use the app to clear the code and monitor for reoccurrence during a test drive.

What vehicles are most commonly affected by C017C?

The C017C code is commonly found in vehicles like the 2015-2019 Chevrolet Silverado, 2016-2019 GMC Sierra, and other GM models from this era. These vehicles may have recalls or technical service bulletins related to ABS performance, so it's worth checking with a dealer.

How can I prevent C017C from happening again?

To prevent the C017C code from reappearing, regularly inspect the wheel speed sensors and their wiring during routine maintenance. Keeping the brake system in good working order, including proper cleaning and protection from road debris, can help avoid future issues.

What is C017C?

The C017C diagnostic trouble code (DTC) indicates an issue with the vehicle's wheel speed sensor circuit. This code is common in vehicles like the 2015-2019 Chevrolet Silverado. When the onboard diagnostic system detects that the wheel speed sensor is providing inconsistent data, it triggers this code. Essentially, the wheel speed sensor monitors the rotation speed of the wheels to ensure proper functioning of the anti-lock braking system (ABS) and traction control. If the sensor fails or its wiring is damaged, the ABS may not function correctly, which can compromise safety. As a result, you might notice issues like the ABS warning light illuminating on your dashboard. In practical terms, driving with this code may lead to reduced braking efficiency, particularly in emergency situations. Thus, it's crucial to address this issue promptly to maintain vehicle safety and performance. Ignoring the C017C code could also result in additional repair costs down the line, as related components may become damaged if the underlying issue is not resolved.

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

Symptoms

Common symptoms when C017C is present:

  • The ABS warning light remains illuminated on the dashboard, indicating a fault in the braking system.
  • You may experience a noticeable reduction in braking efficiency, especially during sudden stops.
  • The vehicle may also exhibit erratic behavior during acceleration, such as skidding or loss of traction on slippery surfaces.
  • In some cases, the traction control warning light may also activate, indicating a related issue.
  • You might notice irregularities in the speedometer readings, especially if the wheel speed sensor is malfunctioning.

Possible Causes

Most common causes of C017C (ordered by frequency):

  1. The most common cause of the C017C code is a faulty wheel speed sensor, which has a likelihood of around 70%. This can occur due to wear and tear or exposure to road debris.
  2. A second potential cause is damaged wiring or connectors, which can lead to poor electrical connections. This is often due to corrosion or physical damage, making up about 15% of cases.
  3. Another cause could be a malfunctioning ABS control module, which can lead to incorrect sensor readings and is less common but still possible.
  4. Less common but serious issues include brake system malfunctions that can stem from previous accidents or poor maintenance.
  5. A rare possibility is software glitches in the vehicle's onboard computer, leading to false codes being triggered.
