Does anyone have a picture, or can tell me exactly where the sensors are for this system.
I have the warning on the dash. Cleared once before by pulling the fuse and the refitting. Perhaps coincidence. Now on constantly and my code reader cannot see it.
Battery is maintained constantly on CTEK so I know that is not the problem.
Only other thing I've done recently is remove the undertray to check for a leak so perhaps I may have disturbed something when refitting, as this is when the warning became permanent.

Thanks in advance for any useful information.

 

Maybe this helps X150_2006-2009_Adaptive_Dynamics.pdf

You really need to scan the car with an IDS or SDD, or maybe one of the other aftermarket scanners that can see B, C and U codes.

Without codes, you are kind of shooting in the dark.

 

I have just fixed mine without a code reader. I had the permanent yellow triangle on the dash.
The system is quite simple. There are four sensors, one at each wheel and three accelerator sensors. This goes into a control module behind the rear seat that then sends the voltage to each shock absorber.

Get the wiring diagram and have a look. I traced mine to a faulty suspension height sensor. At the control module , 5 volts is sent out to power the sensors and a signal is returned. On mine, 2.8v was coming back from three sensors but one was at zero.

I unplugged the module and checked the resistance between ground and the signal from each sensor. Three were about 470k ohms and the faulty one 30 ohms. To make sure it was not a wiring short, i disconnected the faulty sensor and measured again. Thai time the resistance went to infinity. I then measured the sensor it self and saw the low resistance there too so I knew it was faulty.

I also checked each actuator coil from the shock absorber and these all read about 2.8 ohms and all the same so i knew these were fine.

One final thing I did was unplug the faulty sensor , bridge an output from a good sensor to the faulty ones input on the control module, then start the car.

I got no yellow triangle and was able to select winter and dynamic mode which I wasn't able to do when it was faulty

I finally got a second hand sensor from a XF and fitted it and all came good.

So it can be done with no code reader , it just takes a lot more time to do but is more satisfying.

If you need help, just ask as you do have to be handy with a multimeter

 

Thanks guys, gives me something to be going on with.

Thanks Cambo but mine is a 5.0L version.

 

Oops I read the 2009 bit but missed the 5.0L, here try this one 2010_XK_Dynamic Suspension.pdf

 

Thanks Cambo that's exactly what I was looking for.

 

This is an advanced level troubleshooting lesson! Well done.

 

Or if you had a code reader which reads chassis codes it would have told which sensor was open circuit

But old school trouble-shooting shouldn't be shunned either

 

You kids and your fancy toys...I use a map and compass instead of my gps. And cans with a string instead of a phone.

The one thing that really bums me out is my ice maker stopped working. Constantly filling old school ice trays is below average. I need your trick reader on that task darnit.

All in good fun!

 

Just had this come on my 2010 XKR did clear once but perm active

scanned with sdd which is saying code U043A92 invalid date from suspension control module B

Was going to re programme module but thought better of it as car is under jag warranty at present

Where did you got to with your Jimbo?

 

Having finally got round to removing the back seats to get to the module, voltage checks pointed to the front right height sensor being faulty.

Disconnected the arm and operated the sensor by hand and found it to be very ratchety.

Purchased a new one, fitted and now everything is back to normal.

Now back to having some fun.

 

m20nuts couldn't have said it better. I recently had the exact same scenario and it also was traced to ride height sensor, as he stated. That's where I would look first.

 

Thanks for all the information!!


Im having this problem as well but a little different,


ABS not available, DSC not available, Adaptive Dynamics not available.


Also it says my front right tire pressure is low, but I checked it by hand
and it is normal.


Where should I start? I have a multimeter, but do not have proper diagnostic tool.


Guidance please.

 

To be honest, start with charging the battery and try again. If the faults remain then the next place to look would be the wheel sensors.

 

Battery voltage is sat, but i'll give it a charge anyway,

there was some heavy rains i drove through lately, i'm thinking
one of my height sensors might have been wetted

 

The height sensors are pretty much waterproof but it wouldn't hurt to check the connectors. It's the ABS warning that makes me think first of the battery and second of the wheel sensor.

 

That makes sense! i will inspect the wheel speed sensors,
snap some pictures,

thanks

 

What a jewel of a contribution to Jaguar and its owners.
Its the sort of stuff they could put in the repair manual for dealer.
As in check here first.

 

I inspected all 4 wheel speed sensors, everything looks good,
after that I managed to get JLR SDD working, and did a full scan on my vehicle
Heres what I came up with:

I'm pretty clueless on what to do next.. help!

-Control module output power A Lost communication
with instrument cluster control module
-Front left wheel speed sensor
-Antenna circuit
-Front right height sensor
-Steering angle sensor
-Invalid data received from the suspension control module B
-Invalid data received from ABS control module Invalid data received from ABS control module
-Front left wheel speed sensor
-Control module microprocessor B Park aid ignition Number plate lamps

Thanks in advance!

 

First thing now you have them recorded is to clear the lot, go for a 30 min drive and then see what comes back.

From your list I would say your front left wheel sensor and front right height sensor are causing your problems.
