Code C124F 2017 GMC Sierra Description
The C124F diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the lateral acceleration sensor circuit, specifically reporting low voltage. The lateral acceleration sensor is a crucial component of the vehicle's stability control system, also known as the electronic stability control (ESC) or traction control system. This sensor measures the vehicle's lateral acceleration, which is the force acting on the vehicle from side to side during cornering or sudden maneuvers. The sensor provides important data to the vehicle's computer system, allowing it to adjust braking and throttle inputs to help maintain stability and prevent skidding.
Common Causes of C124F 2017 GMC Sierra
- Faulty lateral acceleration sensor.
- Damaged wiring or connectors in the lateral acceleration sensor circuit.
- Corrosion or contamination in the sensor or circuit.
- Electrical issues such as a blown fuse or relay affecting the sensor circuit.
- Software or calibration issues with the vehicle's stability control system.
Symptoms of C124F 2017 GMC Sierra
- Illumination of the traction control or stability control warning light on the dashboard.
- Increased tendency for the vehicle to skid or lose traction during cornering or sudden maneuvers.
- Reduced effectiveness of the stability control system in maintaining vehicle stability.
- Erratic behavior of the vehicle's stability control system, such as unexpected braking or throttle adjustments.
How to Fix C124F 2017 GMC Sierra
- Begin by conducting a thorough visual inspection of the lateral acceleration sensor, wiring, and connectors to check for any visible damage or contamination.
- Use a multimeter to test the voltage output of the lateral acceleration sensor and compare it to the manufacturer's specifications.
- If the sensor is faulty, replace it with a new, OEM (original equipment manufacturer) sensor.
- Repair or replace any damaged wiring or connectors in the lateral acceleration sensor circuit.
- Clear the DTC from the vehicle's computer memory using a diagnostic scan tool and perform a test drive to ensure the issue has been resolved.
Cost to Fix C124F 2017 GMC Sierra
The typical repair costs for addressing a lateral acceleration sensor circuit low voltage issue can vary depending on the specific cause of the problem and the labor rates in your area. In general, replacing a faulty lateral acceleration sensor can cost between $150 and $300, including parts and labor. However, additional costs may be incurred if wiring repairs or other components need attention. It's recommended to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on your vehicle's make and model. Keep in mind that diagnostic time and labor rates can vary, so it's advisable to inquire about these factors before proceeding with the repair.
