Are you experiencing issues with the cruise control of your Jaguar? Jaguar’s Adaptive Cruise Control or ACC is one of the technologically advanced features that make highway driving comfortable and secure. While a conventional cruise control system merely sustains a set speed, ACC controls the Jaguar’s speed to maintain a safe distance from the car in front. It can also bring your car to slow motion or even a complete halt in traffic congested areas.
However, like any other advanced system, there are some problems that may arise with the use of ACC over time. Some of the signs that may indicate that your Jaguar’s ACC needs attention include; fluctuating between the speed adjustments, inability to detect vehicles and warning messages. Below are the common ACC problems and their solutions.
Common Problems With Jaguar Adaptive Cruise Control
- Sensor malfunctions: The primary function of ACC is to use radar sensors and cameras to detect traffic ahead. These sensors can be blinded by dust or other particles, or adverse weather conditions, and as such provide wrong information. In some cases, the sensor may be defective in detecting the objects leading to disengagement or improper functioning of the system.
- Fails to Maintain Speed or Distance: Some owners have complained that the ACC of their car cannot maintain a proper distance or its speed is not well regulated. This can be attributed to a faulty sensor, a bug in the software or a flaw in the braking or throttle control systems.
- Warning Messages and System Errors: If the ACC system fails to work, the car’s dashboard may display messages such as “Adaptive Cruise Control not available.” This may be attributed to the radar system, the electronic control module, or software variations that should be analyzed for diagnostics.
- Disengagement Problem: Some Jaguar drivers have reported that the ACC system disengages abruptly while they are on the road. This can be attributed to interference of the sensors, a loose connection in the electronic circuit, or a calibration issue.
- Lack of Effectiveness in Some Circumstances: Jaguar’s ACC system may not be efficient in areas with poor visibility such as when it is raining, foggy or snowing. It can lose the ability to detect vehicles properly due to poor visibility and or obstructions of the sensors and it may disengage or function intermittently. Jaguar owners should know that ACC is not a replacement for safe driving, especially during bad weather.
How To Solve Common Jaguar Adaptive Cruise Control Issues
- Check the Radar Sensor and Front Camera: A simple wiping of the radar sensor and front camera can also help fix the ACC issue. To clean the front grille and windshield, use a soft cloth or a wipe to wipe off the dirt, dust or bugs.
- Turn the Jaguar Off and On: Switching the Jaguar off and on again may help to fix the ACC system. Attempt this first before consulting a professional.
- Look for Warning Lights: If any warning light is on in your dashboard, consult the Jaguar owner’s manual for possible solutions. By using an OBD scanner, you will be able to understand the cause of the message easily.
- Check for Physical Damage: If your Jaguar has been involved in an accident, even a small one, the ACC sensors could have moved or been damaged. They can be realigned by a professional mechanic if needed or replaced as a whole.
- Software Update: Jaguar, like many car manufacturers, updates its software from time to time to enhance the car’s performance. You can visit a Jaguar service center to know if your ACC system requires an update on the software.
