The most common reasons a Mitsubishi Eclipse Cross 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 Mitsubishi Eclipse Cross 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.

Troubleshooting Cruise Control Issues in a Mitsubishi Eclipse Cross

When troubleshooting cruise control issues in a Mitsubishi Eclipse Cross, it's essential to adopt a systematic diagnostic approach. Begin by checking the simplest components, such as the control module, sensors, and switches, as these are often the most common culprits for malfunction. If these elements appear to be functioning correctly, inspect the throttle for any actuation problems that could be impacting the cruise control system. Pay particular attention to the adjustment of the switch located near the clutch pedal bracket, as improper alignment can lead to cruise control failure. Additionally, ensure that all related components, including the clutch and brake switches, ABS, tail light circuit, clock spring, cruise control stalk, engine module, and body module, are in good working order. By following this methodical approach, you can effectively identify and resolve the issues affecting your cruise control system, making your DIY troubleshooting efforts more efficient and successful.

Troubleshooting Cruise Control Issues in a Mitsubishi Eclipse Cross

When troubleshooting cruise control issues in a Mitsubishi Eclipse Cross, it's crucial to understand the common problems that may arise. One frequent culprit is a malfunctioning control module, sensor, or switch, which can disrupt the system's functionality. Additionally, throttle actuation problems can prevent the cruise control from engaging properly, leading to frustrating driving experiences. Low transmission fluid levels or a faulty transmission control module can also contribute to these issues, as they affect the overall performance of the vehicle. If your Eclipse Cross is equipped with a turbocharged engine, be aware that rough idling or poor acceleration can further complicate cruise control operations. For those experiencing difficulties with adaptive cruise control, it's important to note that the system may slow down unnecessarily when no vehicle is detected ahead, which can be annoying for other drivers. Moreover, if the Forward Collision Mitigation (FCM) radar is blocked, the adaptive feature may shut off intermittently, necessitating a switch to regular cruise control. By being aware of these potential issues, you can take the first steps toward diagnosing and resolving cruise control malfunctions in your Mitsubishi Eclipse Cross. If the problems persist despite your efforts, consulting with a professional who specializes in Mitsubishi vehicles may be the best course of action.

Why is the Cruise Control Not Working in a Mitsubishi Eclipse Cross?

When the cruise control in your Mitsubishi Eclipse Cross is malfunctioning, it’s crucial to address the issue without delay. Ignoring symptoms such as an unresponsive control module or a burnt-out brake light can lead to more significant problems, including potential safety hazards while driving. For instance, if the cruise control system is not functioning correctly, it may cause erratic vehicle behavior, which can be dangerous on the road. Additionally, components like the clutch switch or throttle actuator, if left unchecked, could lead to costly repairs down the line. By taking the time to troubleshoot and resolve these issues—whether it’s readjusting a switch or replacing a faulty sensor—you not only enhance your vehicle's performance but also ensure a safer driving experience. Remember, timely intervention can prevent minor issues from escalating into major repairs, making it essential to act swiftly when faced with cruise control problems.
