  • 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.

How much does it cost to fix a 2017 Ram 1500 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.

What are the initial diagnostic steps to take when the cruise control isn't working on a 2017 Ram 1500?

When your cruise control isn't functioning on a 2017 Ram 1500, it's important to approach the diagnosis methodically. Begin by checking the fuse associated with the cruise control system, as a blown fuse can easily disrupt its operation. Next, inspect the cruise control switch to ensure it is working correctly; a faulty switch can prevent the system from engaging. Following this, verify the speed sensors, as they play a crucial role in the cruise control's functionality; if they are malfunctioning, the system may not activate. Additionally, examine the wiring connections for any signs of looseness or damage, as these can also hinder performance. Finally, consider using a diagnostic scanner to check for any error codes that may provide insight into specific issues affecting the cruise control system. By systematically addressing these areas, you can effectively troubleshoot and potentially resolve the cruise control malfunction on your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2017 Ram 1500?

When troubleshooting cruise control issues in a 2017 Ram 1500, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake light switch, which can prevent the cruise control from engaging since it is designed to deactivate when the brake pedal is pressed. Additionally, issues with the speed sensor can disrupt the system's ability to maintain a constant speed, leading to failure. A blown fuse in the cruise control circuit is another simple yet often overlooked problem that can halt functionality; checking and replacing the fuse may quickly resolve the issue. Furthermore, a malfunction in the throttle control system, particularly with the throttle position sensor, can hinder the cruise control's performance. Lastly, problems with the Electronic Control Module (ECM), which oversees various vehicle functions including cruise control, can also lead to operational failures. By systematically addressing these potential issues, you can effectively troubleshoot and restore the cruise control system in your Ram 1500.

How urgent is it to address the malfunctioning cruise control in a 2017 Ram 1500?

When it comes to a malfunctioning cruise control system in your 2017 Ram 1500, the urgency to address the issue cannot be overstated. A faulty cruise control can lead to unpredictable vehicle behavior, such as sudden acceleration or deceleration, which significantly increases the risk of accidents on the road. Ignoring these symptoms not only jeopardizes your safety but also that of other drivers and passengers. Moreover, delaying repairs can exacerbate the problem, potentially leading to more extensive damage to the vehicle's electronic systems, resulting in higher repair costs down the line. Therefore, it is crucial to have the cruise control system inspected and repaired by a qualified mechanic as soon as possible to ensure your vehicle operates safely and reliably. Taking prompt action not only protects you but also helps maintain the overall integrity of your vehicle.
