The most common reasons a Acura TL cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.

How much does it cost to fix a Acura TL 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.

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.

If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.

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.

A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.

Troubleshooting Cruise Control Issues in an Acura TL

When troubleshooting cruise control issues in your Acura TL, it's essential to adopt a systematic diagnostic approach. Begin by checking the cruise control switch on the steering wheel, as a faulty switch can prevent the system from engaging. Next, inspect the fuses located near the driver's foot area to rule out any blown or damaged fuses that could disrupt functionality. If these initial checks do not resolve the issue, proceed to clean the pickups on the front half shaft driveshaft, ensuring they are properly connected. If the cruise control light activates when you press the SET button, this indicates that the system is receiving some input; however, you should still test the cruise throttle cable actuator by examining the wiring for any faults. Additionally, verify the signals entering the controller to confirm that communication is intact. If the actuator appears to be malfunctioning, it may require replacement. Finally, if all else fails, consider replacing the controller, which is accessible behind the dashboard lower cover. By following this structured approach, you can effectively diagnose and potentially resolve cruise control issues in your Acura TL.

What Could Cause the Cruise Control to Malfunction in an Acura TL?

When dealing with cruise control malfunctions in an Acura TL, it's essential to understand the common problems that may arise. One of the primary culprits is a faulty cruise control switch located on the steering wheel, which can prevent the system from engaging properly. Additionally, issues with the control module, throttle sensor, or other related components can disrupt the functionality of the cruise control. Throttle sensor failures are particularly common and can lead to the system not responding as expected. Furthermore, problems with the signals sent to the controller or actuator can also contribute to malfunctioning cruise control. Lastly, a broken filament in the clock spring contact under the steering wheel may hinder the electrical connections necessary for the cruise control to operate. By identifying these potential issues, DIYers can effectively diagnose and address the root cause of their Acura TL's cruise control problems.

Why is the Cruise Control Not Working in an Acura TL?

When the cruise control in your Acura TL fails, it’s crucial to address the issue without delay. Ignoring symptoms such as unresponsive controls or erratic behavior can lead to safety risks, especially during long drives where maintaining speed is essential. A malfunctioning cruise control system may indicate underlying problems, such as a faulty control module or a defective brake pedal switch, which could compromise your vehicle's overall functionality. Additionally, issues like a blown fuse or throttle actuation problems can escalate if not resolved, potentially leading to more significant repairs and costs. By diagnosing and fixing these issues promptly, you not only enhance your driving experience but also ensure your safety on the road. Therefore, if you notice any signs of cruise control failure, it’s advisable to investigate the cause and take action before the problem worsens.
