Land Rover Repair: 2004 Range Rover HSE HDC INACTIVE, range rover hse, obd ii scanner

Question
Hello, I am getting the following messages on my 2004 Range Rover HSE:  HDC INACTIVE as well as the ABS light is on.  Also, I believe that it also said my Suspension is INACTIVE.  Can you tell me what this might possibly mean?

Answer
It means there is a problem with one or more of the sensors that monitor wheel rotation.  With that malfunction the antilock brakes and the hill descent control are disabled.  Take the vehicle to a dealer or a specialist with the T4 or Autologic system and have them read the faults and discuss repair options.  You will not be able to access those systems with a generic OBD II scanner.

Good luck,
John Elder Robison
