The most common reasons a 2010 Mitsubishi Eclipse 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.

How much does it cost to fix a 2010 Mitsubishi Eclipse 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.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

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 steps to diagnose the cruise control issue in a 2010 Mitsubishi Eclipse?

When diagnosing a cruise control issue in a 2010 Mitsubishi Eclipse, it's essential to adopt a systematic approach that begins with the simplest checks before progressing to more complex diagnostics. Start by inspecting the cruise control fuse to ensure it is intact, as a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel for any signs of damage or malfunction, as these controls are critical for operation. Following this, check the speed sensors, which are vital for the cruise control system to function correctly. Utilizing an OBD-II scanner can help identify any error codes that may indicate specific problems within the system. Additionally, ensure that the brake pedal switch is operational, as it is designed to disengage cruise control when the brakes are applied. Inspecting the vacuum lines for leaks or damage is also crucial, as these can significantly affect performance. Finally, test the cruise control module to confirm it is communicating effectively. If these steps do not resolve the issue, seeking assistance from a professional mechanic with experience in Mitsubishi vehicles may be necessary for a thorough diagnosis and repair. This methodical approach not only helps in identifying the problem but also saves time and resources in the troubleshooting process.

What are the common problems that could cause the cruise control to stop working in a 2010 Mitsubishi Eclipse?

When dealing with a malfunctioning cruise control system in a 2010 Mitsubishi Eclipse, it's essential to understand the common problems that may be at play. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging or disengaging properly. Additionally, a blown fuse can disrupt the entire cruise control operation, so inspecting the fuses is a crucial step. Another potential issue is vacuum leaks, which can interfere with the system's functionality, making it vital to examine the vacuum lines for any signs of wear or damage. The speed sensor also plays a critical role; if it's defective, it can lead to inaccurate speed readings, causing the cruise control to malfunction. Furthermore, the brake light switch should be inspected, as a faulty switch can prevent the cruise control from engaging when the brake pedal is pressed. Lastly, issues with the throttle cable, such as fraying or stretching, can hinder the system's ability to maintain a constant speed. By systematically checking these components, DIYers can effectively diagnose and resolve cruise control issues in their Mitsubishi Eclipse.

How urgent is it to address the non-functioning cruise control in a 2010 Mitsubishi Eclipse?

When it comes to a non-functioning cruise control in a 2010 Mitsubishi Eclipse, the urgency of addressing the issue cannot be overstated. While it may not seem like an immediate emergency, neglecting this problem can lead to significant safety risks and inconvenience. A malfunctioning cruise control system may indicate deeper issues within the vehicle's electronics or mechanical components, which could affect other critical systems. This is particularly concerning as it may compromise the overall safety of the vehicle, especially during long drives where maintaining a steady speed is crucial. Furthermore, the inability to utilize cruise control can lead to driver fatigue and decreased fuel efficiency, making long trips more taxing. Therefore, it is advisable for DIY enthusiasts to investigate the root cause of the malfunction as soon as possible, whether through troubleshooting common issues or consulting a qualified mechanic. By addressing the problem promptly, you not only enhance your driving experience but also ensure the safety and reliability of your Mitsubishi Eclipse on the road.
