What Does The HDC Do In Land Rovers?

by schearerswpadmin December 5, 2018

Land Rovers feature the HDC, which stands for Hill Descent Control system. A driver-assistance system, the HDC allows for controlled hill descent in rough terrain without the driver having to do any braking. When the HDC is turned on, the vehicle will use the anti-lock braking system during descent to control the speed of each wheel on the vehicle. The driver can use cruise control to adjust the speed to a level that is comfortable. If the driver applies the brake pedal, the HDC system will be overridden.

The HDC was originally developed by Land Rover for use in the Freelander because it doesn’t have the lower range gears that are usually provided for four-wheel drive vehicles. When the HDC was first introduced, some people complained that the set speed was too fast for a controlled descent in conditions that were difficult or challenging. However, the technology used in the HDC was state of the art, and with the traction control system allowed the Freelander to stand out in its division in the 1990s. Later, the HDC was implemented in the Range Rover and Discovery where it was combined with low-range gears and traction control, so it could have the set speed reduced for extra control.

How Does Hill Descent Control Work?
HDC allows you to safely and smoothly descend hills when in rough terrain without having to apply the brake pedal. You can turn HDC on if you are traveling at 50 miles per hour or less, but it will only work when going 31 miles per hour or less. You can use HDC when the vehicle is in drive, reverse, or any gear. When you engage the gearbox in drive, the vehicle will automatically select the gear that is most appropriate.

After you have set the HDC, the target speed will be shown by a green marker on the speedometer. When HDC is turned off while in operation, the light will flash, and the system will fade out until the vehicle speed slowly increases. If HDC has been turned on and the vehicle is traveling faster than 31 miles per hour, then HDC will be suspended. There will be a message appear in the message center and the HDC light will flash. If the vehicle goes faster than 50 miles per hour, HDC will disengage and the HDC light will go off.

Other HDC Details
If the brake pedal is applied while HDC is turned on, the driver might feel a pulsation through the brake pedal. HDC will resume after the brake pedal is released. If the vehicle was operating with HDC on and then the motor is turned off, HDC will automatically turn off after the ignition has been turned off more than 6 hours. Each gear has a predetermined maximum speed while HDC is in operation. Vehicle speed will only increase when the vehicle is on a slope that is steep enough to increase vehicle momentum. There is a predetermined minimum speed for each gear as well. If there is a problem detected in the HDC system, the message center will indicate HDC Fault System Not Available and the HDC assistance will gradually fade out.

HDC Problems
If your vehicle’s HDC system is not functioning properly, you should have it inspected by a qualified Land Rover automotive technician. You shouldn’t attempt a steep descent if the HDC is not working or if it is displaying a warning message. Sometimes the problem could be a simple fix, but it could be something more problematic that requires a more in-depth fix. The mechanic will be able to troubleshoot the problem and determine the proper fix. With a scan device, the technician will get codes that give him or her an idea of the problem and can troubleshoot from the information that is provided.

what people say about us

Excellent & timely service – keep up the great job!! =D

Excellent service. Work done on time as promised.

Just got back from having a turn signal bulb replaced… For $133… Bulb is available for $7.98 online, but the intensive training required to unscrew the old bulb and screw in the new one must have been very costly indeed. Was looking for a new place to go for service on my GTI. Got a postcard saying “you don’t have to go to the dealer” As horrible as the dealer is, I very certainly would have been much better off. Oh, and they charged me $80.00 for the bulb! I said that’s some real markup on that and they told me it was 65% markup as they bought it for $25.00… Unbelievable.

You always take good care of my daughters car. Fast reliable and honest service.

Very Professional and Through in their Work. They have my Trust in their recommendations.

Always professional. I’m a 7 year customer. I’ve had several vehicles serviced here and I’ve never had to worry that the work wasn’t done properly.

You are always very helpful to me. Had my car ready on time , the time I said needed it. No loaner cars available but so good of Rayanne and Christie to get me back and forth. Thank you so much.

Thank you for polite and professional service!

Work nicely done at a reasonable price – made recommendations for (necessary!) additional work I hadn’t considered. Left one wire disconnected, but that was promptly and properly corrected. Thanks!

Service at Schearers is always meticulous and professional. The work for which I brought my car in was done well, and an inspection of potential future problems was also undertaken, enabling me to plan for future maintenance to keep my car running smoothly. I am satisfied, as always, with the quality of work and the professionalism of everyone I encountered at Schearers.

Excellent service as usual. Work was done in a timely fashion at a reasonable price. I really like the loaner car arrangement. Mike was very nice to schedule service on the same day and get the necessary parts quickly. Samantha provided a coupon from the internet. Thanks

Friendly service and fair pricing.

Very personable owner/ family. Made us feel comfortable. Explained everything that was necessary for our car upkeep. Prices better than other foreign car dealerships. Car was completed in a timely manner. Will recommend to friends. Thank you

I wish I had found them earlier! Great company and very talented group of mechanics, specializing in German cars. They do excellent work and you’ll save a lot of money over the dealer.

Great service. I would recommend this service center to every one. Very professional and courteous. Always get the job done right.

Polite, helpful staff and professional service always!

Great experience! From the first call I made and spoke with Kristy to Mike walking me through and explaining what he was going to do. Mike also did an evaluation and let me know what to expect regarding services my car will need in the future. Exceptional customer service from beginning to end, including Samantha taking my payment. I told Mike, I am a customer for life! Well done Scherrers!! Jim Rowlands

The headlight lens cleaning was great. Thanks for suggesting.

Shearer’s yet again provided exceptional service! I am always informed of any maintenance requirements, reasons for, and associated costs before any actions are taken.

I highly recommend Shearer’s to service your car!

Always very nice and accommodating being that I live in Vermont. Will definitely have them maintain my sons car for the next 2 years while he attends school in PA.
