Hi all

I am currently getting a hdc fault followed by special programmes disabled and suspension lowered.

I have tried removing the battery and charging it

This fault has only come in since I have replaced the lower wishbone. Vehicle was fine before this.

Does anyone have any other suggestions to try or does it need plugging in?

Many thanks

David

Welcome.

Did you have a full alignment after the wishbones were fitted? Was the Steering Angle Sensor (SAS) calibrated (If not, then I highly suspect this is the issue)?

Additionally, have you checked stuff like the height and ABS sensor wires that could have been disturbed?

Oh, and best to fill in your vehicle profile (if you think you have, check you've selected the colour).  Visiting from DISCO3.CO.UK

I did the wish bones so no alignment yet

And how do I calibrate the steer angle sensor?

Thank you

It needs a diagnostic tool to calibrate it, but you also need to get the alignment done ASAP.  Visiting from DISCO3.CO.UK

is there anyway to physically check the abs sensors or does it need plugging in for this ?

Needs to be plugged in to read the data from them, but you could check for physical damage to the wiring etc. I think it highly likely that the issue is the SAS and/or alignment though.  Visiting from DISCO3.CO.UK

okay thank you I am going to get it plugged in tomorrow and hopefully sorted

Hi , i had the same problem, start the car up and do full left lock , and then full right lock, also check brake pad wear sensors...
ensure tracking is also set up as well

I have the same problem
changed the battery no joy on that
brake peddle switch no joy
full left and right lock no joy..
next task is the unit under the passenger wheel arch, unplug it and checking for rusty pins...
let me know what your outcome is plz...

The steering angle sensor needs calibrated using a diagnostic machine, not by working the steering lock to lock

Had the same problem, changed the brake light switch under the dash and all was well again  RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED
EVERY POSSIBLE SOFTWARE UPDATE INCLUDING - BLUTOOTH UPDATE, SATNAV ON THE MOVE, CLOCK ON DASH, 3 CLICK FLASH, GEARBOX RESET, COMPRESSOR UPDATE AND SUSPENSION LOWERED,
BLACK CODE RE-MAPPED, AUTOBIOGRAPHY'D, NEW EXIDE BATTERY, NEW DENSO ALTERNATOR

A blown brake light bulb can throw an HDC error too. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I have the new updated LED'S on the rear,
