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.
When diagnosing a cruise control issue in a 2012 Dodge Durango, it's essential to adopt a systematic approach that begins with the most straightforward checks before progressing to more complex diagnostics. Start by ensuring that you are engaging the cruise control correctly, as improper usage can often be the culprit. Next, inspect the relevant fuses, particularly the 10A fuse F82 in the Power Distribution Center, to confirm they are intact. A malfunctioning horn can indicate broader electrical issues, so test it to rule out any electrical faults. The brake light switch is another critical component; it should activate the tail lights and deactivate the cruise control when the brake pedal is pressed. Use a multimeter to test its functionality, as a faulty switch can prevent cruise control from engaging. Employing a professional-grade diagnostic tool can provide insights into the system's status, allowing you to check for error codes and monitor switch inputs. Additionally, assess the condition of the control module, speed sensors, and throttle actuation, as these components can also affect cruise control performance. Lastly, ensure that the traction control system is not interfering with cruise control functionality. By following this structured diagnostic approach, you can effectively identify the root cause of the issue and determine whether further professional assistance is necessary.
When dealing with cruise control issues in a 2012 Dodge Durango, it's essential to understand the common problems that may arise. One frequent culprit is a faulty brake light switch, which plays a crucial role in deactivating the cruise control when the brake pedal is pressed. If this switch malfunctions, it can prevent the cruise control from engaging properly. Additionally, the cruise control switch or the buttons on the steering wheel may wear out over time or become damaged due to spills or cleaning agents, leading to operational failures. Another area to investigate is the vehicle's fuse; specifically, the cruise control is linked to a 15 amp fuse located in the Totally Integrated Power Module (TIPM). A blown fuse can easily disrupt the system. Furthermore, issues with the ABS or speed sensors can also hinder cruise control functionality, often accompanied by warning lights on the dashboard. Lastly, electrical problems or integration issues between various vehicle systems can complicate matters, making it beneficial to use an OBD scanner to diagnose any underlying faults. By systematically checking these components, DIYers can effectively troubleshoot and potentially resolve cruise control issues in their Durango.
While the malfunctioning cruise control in a 2012 Dodge Durango may not seem urgent from a safety standpoint, it is essential to recognize that neglecting this issue could lead to more significant problems down the line. The convenience of cruise control is often taken for granted, but its absence can make long drives less enjoyable and may indicate underlying issues that warrant attention. For instance, a faulty brake light switch, which is a common culprit for cruise control failures, can also compromise the functionality of your brake lights, posing a safety risk to you and other drivers. Additionally, problems with speed sensors or ABS sensors can affect your vehicle's stability and traction control, further emphasizing the need for timely diagnosis and repair. Therefore, while you may not need to rush to a mechanic immediately, it is advisable to investigate the root cause of the malfunction to prevent any potential safety hazards or costly repairs in the future. Taking proactive steps, such as checking the fuse, brake light switch, and steering wheel buttons, can help ensure your vehicle remains safe and reliable.
