How much does it cost to fix a 2017 Toyota 86 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 troubleshoot the non-functioning cruise control in a 2017 Toyota 86?

When troubleshooting the non-functioning cruise control in a 2017 Toyota 86, start with the simplest solutions before moving on to more complex diagnostics. Begin by checking the cruise control fuse; a blown fuse is a common issue that can easily be resolved by replacing it. Next, verify the functionality of the cruise control switch, as a malfunctioning switch can prevent the system from engaging. It's also essential to inspect the brake pedal switch, since a faulty switch can disable the cruise control as a safety precaution. Additionally, examine the vehicle speed sensor to ensure it is accurately sending signals to the cruise control module, as any discrepancies here can lead to operational issues. Finally, if the problem persists, consider using a diagnostic scanner to check for error codes that may indicate specific faults within the cruise control system. By following these steps, you can effectively diagnose and potentially resolve the cruise control issues in your Toyota 86.

What are the common problems that could cause the cruise control to stop working in a 2017 Toyota 86?

When troubleshooting cruise control issues in a 2017 Toyota 86, it's essential to understand the common problems that may lead to its malfunction. One of the primary culprits is a faulty brake pedal switch, which can inadvertently signal the system to disengage, preventing proper operation. Additionally, a malfunctioning speed sensor can disrupt the system's ability to maintain a constant speed, as it relies on accurate readings to function effectively. Another potential issue is a blown fuse; checking and replacing the fuse associated with the cruise control system can often resolve the problem. Throttle control issues, such as a sticky throttle or problems with the throttle position sensor, can also interfere with the cruise control's performance. Furthermore, the Electronic Control Module (ECM) plays a critical role in managing various vehicle functions, and any issues with it can lead to cruise control failure. Lastly, wiring problems, including faulty connections, can hinder communication between components, resulting in a non-functional cruise control system. By systematically addressing these common issues, you can effectively troubleshoot and restore the cruise control functionality in your Toyota 86.

How urgent is it to repair the non-functioning cruise control in a 2017 Toyota 86?

When evaluating the urgency of repairing the non-functioning cruise control in your 2017 Toyota 86, it's essential to recognize the potential safety risks associated with this issue. A malfunctioning cruise control system can lead to erratic vehicle behavior, such as unexpected acceleration or deceleration, which poses a significant hazard on the road. Additionally, the absence of this feature can detract from your driving comfort, especially during long trips, as it requires constant foot pressure on the accelerator, leading to fatigue. Furthermore, neglecting this repair can impact your vehicle's resale value; prospective buyers often look for well-maintained features, and a functioning cruise control system is typically expected. Therefore, while it may not be the most critical repair, addressing the cruise control issue promptly is advisable to ensure your safety, enhance your driving experience, and preserve the value of your Toyota 86.
