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.
To effectively diagnose the non-functioning cruise control in your 2012 Toyota FJ Cruiser, begin with the simplest solutions before progressing to more complex diagnostics. Start by checking the fuse associated with the cruise control system; a blown fuse is a common and easily fixable issue. If the fuse is intact, utilize an intelligent tester to assess the system's electronic control module (ECM) and check for any diagnostic trouble codes (DTCs) that may indicate specific problems. Next, test the brake switch, as an improperly functioning switch can interrupt the cruise control's operation; you can do this by holding the brake pedal up while attempting to engage the cruise control. Additionally, observe the instrument panel for the cruise control light; if it’s absent, further investigation into the wiring may be necessary. To differentiate between types of cruise control issues, try activating the constant speed feature, which can help isolate the problem. Finally, perform sensor diagnostics by cycling through cruise functions and checking the speed sensor, as these components are crucial for the cruise control's functionality. By following this structured approach, you can systematically identify and address the issues affecting your vehicle's cruise control system.
When it comes to the non-functioning cruise control in a 2012 Toyota FJ Cruiser, understanding the urgency of the situation is crucial for both safety and driving comfort. While a malfunctioning cruise control system may not pose an immediate safety risk, neglecting the issue can lead to more significant problems down the line. For instance, if the cruise control is not engaging due to a blown fuse or a faulty brake switch, these minor issues can escalate into more complex electrical or mechanical failures if left unaddressed. Additionally, the inconvenience of not having cruise control during long drives can lead to fatigue and discomfort, impacting your overall driving experience. Therefore, it is advisable to assess the symptoms promptly and consider repairs, especially if you frequently drive on highways or long distances. Regular maintenance checks can help identify potential issues early, ensuring that your vehicle remains in optimal condition and enhancing your driving comfort and safety.
