The most common reasons a Ram C/V cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a Ram C/V cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

Troubleshooting Cruise Control Issues in a Ram C/V

When troubleshooting cruise control issues in a Ram C/V, it's essential to adopt a systematic diagnostic approach. Begin by checking the brake pedal sensor, as this component plays a crucial role in the cruise control system's functionality. If the sensor is malfunctioning, it may prevent the cruise control from engaging. Next, verify that the cruise control system is activated and that the speed limit is correctly set; sometimes, the issue can be as simple as an incorrect setting. Inspecting the control module, sensors, and switches is also vital, as failures in these areas can lead to erratic speed behavior. Additionally, check for blown fuses related to the cruise control system, as a blown fuse can disrupt its operation. Assess the condition of the brake pedal and throttle body, ensuring they are functioning properly, as their performance directly impacts cruise control functionality. Finally, if the problem persists, using a diagnostic scanner can help identify specific issues by providing error codes and insights into the speed sensor's operation. By following this structured approach, you can effectively diagnose and resolve cruise control problems in your Ram C/V.

What Could Cause the Cruise Control to Malfunction in a Ram C/V?

When troubleshooting cruise control malfunctions in a Ram C/V, it's crucial to identify the common problems that may be at play. A faulty control module is often a primary suspect, as it governs the cruise control system's operations. Sensor issues, particularly with the throttle or speed sensors, can also disrupt functionality, leading to erratic behavior or complete failure. Wiring problems, such as frayed or loose connections, may prevent the system from receiving the necessary signals. Additionally, the brake pedal sensor plays a vital role; if it malfunctions, it can mistakenly signal that the brakes are engaged, disabling the cruise control. Checking for blown fuses is another important step, as these can cut power to essential components like the cruise control switch and speed sensor. Lastly, defective parts, including the cruise control switch, throttle control system, or vacuum lines, can contribute to the issue. By methodically examining these areas, you can effectively diagnose and resolve cruise control problems in your Ram C/V, ensuring a smoother driving experience.

Why is the Cruise Control Not Working in a Ram C/V?

When your Ram C/V's cruise control system fails, it’s crucial to understand the potential risks and consequences of ignoring the problem. A malfunctioning cruise control can not only lead to an uncomfortable driving experience but also pose significant safety hazards. For instance, if the brake pedal sensor is faulty, it may not disengage the cruise control when you need to slow down, increasing the risk of an accident. Additionally, issues with the throttle actuation or control module can lead to erratic speed fluctuations, making it difficult to maintain a safe driving speed. Neglecting these symptoms could result in more severe damage to the vehicle's systems, leading to costly repairs down the line. Therefore, if you notice any signs of cruise control malfunction, such as unresponsiveness or erratic behavior, it’s essential to diagnose and address the issue promptly to ensure your safety and the longevity of your vehicle.
