Reasons Why Your Land Rover’s HDC May Fail From Certified Technicians in Chattanooga

Reasons Why Your Land Rover’s HDC May Fail From Certified Technicians in Chattanooga

Land Rover is known for their expertly-engineered vehicles which deliver unparalleled performance in city, rural, and off-road driving. This causes Land Rovers to experience their own unique set of problems. As a Land Rover owner, you may be familiar with the HDC feature, which is the Hill Descent Control. If this part fails, it can put you and your passengers in danger. Let’s take a closer look at this important component.

The Function of the Hill Descent Control

Hill Descent Control (HDC) is a feature first debuted in Land Rover’s Freelander model. The HDC was designed to enhance Land Rovers as off-road vehicles. It combined an innovative traction control system with the engagement of its Anti-Lock Braking System (ABS). Consequently, the Freelander is the first model to showcase the HDC’s ability to provide smooth, controlled descent using a similar mechanism to cruise control. The HDC elevated the Land Rover brand to the highest status among off-road vehicles of their class.

The groundbreaking technology allowed the ABS to control the speed of each descending wheel individually in order to control the effects of sudden acceleration. Wheels that were being affected more strongly by uneven terrain and friction could be slowed to better control the descent of the entire car.

Causes of HDC Failure in Land Rovers

While this ground-breaking technology allows for greater security and confidence while maneuvering a Land Rover downhill while off-road, it also puts a great deal of responsibility on this system. If HDC fails in a Land Rover, a driver would suddenly have much less control of their car on a potentially-dangerous off-road path. Many drivers count on this system to get them out of precarious driving conditions. If this system fails, injuries could occur, and your Land Rover may need a tow for repairs.

In order to prevent HDC failures, Land Rover has created a number of messages that will notify you that the HDC needs servicing.

For example, if you are traveling at speeds above 30mph or your brake system is overheating, the HDC will not be available for you to use. This prevents you from relying on the HDC in a situation where it would fail and put you at risk. Once conditions are favorable again, such as you have slowed down or have waited until your car’s system cooling has reduced the temperature of your brakes, then you will be able to engage HDC and use it for an off-road descent.

In order to operate, HDC needs to use low gears, but the system can also be used in gear one, drive, and reverse. A message to change to an appropriate selection will appear so that you do not try to engage the technology with the wrong gear.

These types of messages will allow you to troubleshoot and figure out what conditions need to change to properly use HDC in your off-road driving. If you receive the message “HDC Fault System Not Available,” it’s important that you have your Land Rover inspected by the appropriate specialist immediately to address the problem.

Each of the messages are programmed to appear for your safety while driving your Land Rover. So, if you see the warning messages, it’s important that you don’t try to continue to use HDC or drive down any steep off-road paths while relying on the system. Instead, stay on smooth roads and bring your car in to be serviced as soon as possible.

Dear Valued Customers,

After conferring with State and local officials and based on the relatively small number of personal interactions involved in our daily operation we have decided to continue to function and will be open regular hours. We aim to provide safe and reliable service to our customers, thus implementing measures that limit exposure to novel COVID-19 / SARS-CoV-2 will aid in meeting and maintaining our safe service aim. Pursuant these aims, to ensure that vehicles are the safest possible during this COVID pandemic, in addition to limiting access to the inside of our shop, we are chemically treating (diluted sodium hypochlorite, aerosol cleaners) every vehicle. Additionally, we are quarantining vehicles for one day when the vehicle is dropped off for repair and before it is returned to the customer. When scheduling service for vehicles, the customer is to park in one a numbered spaces beyond the gate. Upon arriving at the shop, park the vehicle in that designated area, turn off the air conditioning system, then place keys in the after-hours drop box (white door by the garage door). Upon service completion, the vehicle is returned to the designated spot by a technician, re-cleaned, and re-quarantined for one day before release to the customer.

We are here to support all of our clients as best we can for as long as we can. Don’t hesitate to call the shop with questions.
