How much does it cost to fix a 2012 Land Rover LR2 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 initial checks should I perform for cruise control issues in a 2012 Land Rover LR2?

When troubleshooting cruise control issues in your 2012 Land Rover LR2, start with the simplest checks to efficiently diagnose the problem. Begin by testing the cruise control buttons on the steering wheel to ensure they are operational, as these are crucial for activating the system. Next, observe the dashboard light associated with the cruise control; it should illuminate when the system is engaged, indicating that the control unit is receiving the correct signals. Following this, inspect the vacuum lines connected to the cruise control module, particularly on the passenger side, for any signs of leaks or damage that could disrupt functionality. Additionally, assess the vacuum pump and the wiring between the Cruise Control Electronic Control Unit (ECU) and the vacuum pump, as any faults here can prevent the system from working properly. Lastly, confirm that all speed control switches are correctly connected and functioning, as these components play a vital role in maintaining the desired speed. By systematically performing these checks, you can effectively narrow down the potential causes of the cruise control malfunction and determine the next steps for repair.

What common issues cause cruise control failure in a 2012 Land Rover LR2?

When dealing with cruise control failure in a 2012 Land Rover LR2, it's essential to understand the various common problems that could be at play. One of the primary culprits is the cruise control amplifier, which can malfunction and disrupt the entire system. Additionally, faulty vacuum hoses are often overlooked; these hoses are crucial for maintaining the necessary pressure for the cruise control to function properly. If there are leaks or blockages in the vacuum lines connected to the cruise control module, this can also prevent the system from engaging as intended. Furthermore, unresponsive cruise control buttons on the steering wheel can lead to operational failures, making it difficult to activate or adjust the cruise control settings. Lastly, issues with the brake switch or the electronic control unit (ECU) can significantly impact the cruise control's functionality, as these components are integral to the system's operation. By understanding these common issues, DIYers can effectively diagnose and address cruise control problems in their Land Rover LR2.

How urgent is it to address the non-functioning cruise control in a 2012 Land Rover LR2?

Addressing the non-functioning cruise control in a 2012 Land Rover LR2 is crucial for maintaining both safety and optimal vehicle performance. Ignoring this issue can lead to significant inconveniences, especially during long drives where cruise control is invaluable for reducing driver fatigue and maintaining a steady speed. A malfunctioning cruise control system may also indicate underlying problems that could affect other vehicle functions, such as acceleration and speedometer accuracy. Moreover, the potential for safety risks increases if the cruise control system fails while driving, particularly on highways or during extended trips. Therefore, it is essential to promptly check for common issues, such as blown fuses, and to investigate any faults in the control module that monitors the speed sensor signal. By addressing these concerns quickly, you can ensure a safer driving experience and prevent further complications that could lead to costly repairs down the line.
