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.
To effectively diagnose the non-functional cruise control in your 2002 INFINITI I35, start with the simplest checks to avoid unnecessary complications. Begin by inspecting the fuses related to the cruise control system, as a blown fuse can often be the root cause of the problem. Next, verify that your brake lights are functioning correctly; they should illuminate when the brake pedal is pressed and turn off when released, as faulty brake lights can interrupt the cruise control operation. Consulting the service manual for the cruise control system will provide you with valuable symptom charts and diagnostic steps tailored to your vehicle. Additionally, use an OBD-II scanner to check for any trouble codes that may indicate underlying issues, especially if the check engine light is illuminated. Finally, assess the cruise control sensor, as its proper functionality is essential for the system to operate effectively. By following these initial steps, you can systematically identify and address the issues affecting your cruise control system.
Repairing the non-functioning cruise control in your 2002 INFINITI I35 should be treated as an urgent matter, as neglecting this issue can lead to several inconveniences and potential safety risks. While the immediate impact on vehicle performance may seem minimal, the inability to maintain a constant speed can result in increased driver fatigue, especially during long trips. This constant manual speed adjustment not only detracts from the overall driving experience but can also lead to erratic acceleration, which poses a risk to both the driver and other road users. Furthermore, a malfunctioning cruise control system can negatively affect fuel efficiency, leading to higher fuel costs over time. Therefore, addressing this issue promptly is essential to ensure a safer, more comfortable, and economical driving experience in your INFINITI I35.
