The dreaded adaptive dynamics fault

I have just got the adaptive dynamic fault. I have inspected the leads on all 4 shocks, they all look ok. As my old scanner did little as far as diagnostics, I purchased the Icarsoft LR V3 to attempt to narrow the problem to one corner. The scanner only gives me code "C1B14-1C" "PERMANENT SENSOR SUPPLY 1". Does anyone have a clue where I should look with this information??

In the workshop manual there's a file called diagnostic codes to look up codes. Download from Wiki (scroll to bottom of the page) 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Thanks Dr. Rob! It appears to be a code for power supply for the lower accelerometer or transducer. Wonderful... Now can anyone with more knowledge than I tell me where to go from here?

The system uses 3 accelerometers. The easy one to access is on the right rear side of the spare wheel well and is also the easiest to damage so start there. I think the others are hidden behind body panels. 2012 TDV8 Vogue (L322)

Have you had the spare wheel out or jacked up the car to get a wheel of the ground?

I ask because the code you give is showing in the WM (link)

https://drive.google.com/file/d/0Byv5LFgQZ...yXSlJt_k7A

as C1B14-1C

is for height sensors

the next one C1B15-1C is for accelerometers.

If you haven't done either then it is quite possible it is the front damper wiring. It does sometimes appear to be OK but my be broken inside the sheath giving a fault.

I may be well out but HTH. Cheers

Hi. I fitted two new solenoids and soldered the wires. No problem since. They're cheap Smile Ken ----------------

As I've just purchased this "big brother" to my '11 Jag XKR back in October, I haven't done anything but change the oil and the wipers. I've had some time today to read as much literature as possible on this issue (and many others) Smile my fullfat folder is growing quite large and I will be using this new found knowledge for the CD player, the front cigar lighter receptacles and the rear entertainment quirks. From what I have found, C1B14-1c relates to Sensor supply 1
Lower lateral accelerometer or pressure transducer supply circuit: short circuit to other circuit or ground.
Lower lateral accelerometer fault
Pressure transducer fault

One other thing, the air will go out of the front shocks overnight. This was ocurring before the AD fault.
I will be checking for leaks.

So.. my mistake! The definition 0f DTC c1b14-1c that I had read over earlier pertaining to the accelerometer was from a 2006 RRdocument. RJFF directed me to the google docs RRWM from 2014 and it says this DTC is for the height sensors. I won't ask why... but why??? Thanks for the insight. Anyone with knowledge of best methods for testing will be my next best friend! Cool
