Hey guys I need some help. I'm at my whits end.
2010 XK coupe 5.0L
my car just turn over 90k miles and I decided to replace my struts because I felt it was about time and the dynamic button never seemed to do anything sense I owned the car.
I installed 4 new struts. Belstein (green) in the rear and jaguar (belstein black) in the front. Everything went smoothly with no problems. After I moved the car ADAPTIVE DYNAMIC FAULT came up on my gauge cluster.
when i used a matco scanner it shows code C110F-64 RR damper solenoid. After doing dome diagnostics, I find out that is the plug that is in the top of the strut. To test if this was the problem i extended the wires for the RR sensor and the LR strut and swapped the plugs (R on L, L on R) cleared the code and moved the car. Same code came up so i k how it's not the strut.
All 4 strut solenoids measure 5.9 volts. With the control module unplugged and the car parked on a decline the front struts measured 3.2 ohms and the rear measured 5.5 ohms.
All fuses tested good. I've inspected the wires for the RR and they are perfect.
The only thing that I can think of is that the control module went bad when I changed out the struts. I dont know how that would have happened. Thoughts?
I would like to fix this and have a dynamic suspension. It's always been firmer than what I think it should be but if I could at least bypass it to turn the light off I'd be willing to except that.
i think if i take it to the dealership they wont know how to fix it and charge me a lot of money for virtually nothing.

 

If your rear struts are measuring 5.5 ohms, then they are likely to be first generation (07-09) CATS units.
2 to 3.5 ohms in the resistance is normal for '10 and newer Adaptive units.

I measured it previously over a month ago and I think it was around 3 ohm. I think the difference is because it's on a decline but I'm not sure. Over the weekend I will measurements on flat ground to see if I see a difference.

 

Resistance of a coil is resistance of a coil. Strut compression should have nothing to do with it.
Sorry.

 

What's the part numbers??

I know it's a long shot but can the module for the 2010 be swapped out for a 2007-2009 I highly doubt but worth looking at before you remove and swap over .

I know it's too late now but I've written on previous forums to always plug in the new strut (regardless of manufacture) to see if they are faulty before installing, make sure you do this if you need to swap them out again .

As suspected, not the correct shock.

Clever name is correct that is for the 4.2 xk/r. (Rear strut)

Can you also provide the part number for the front shocks so we can also check for you .

 

Won't hurt to double check, but with a resistance measurement of 3.2 ohms, the fronts are spot on for a 2010.

The fronts are C2P17670

If they were the wrong struts, why wouldn't both show a code?

 

I ordered my rear struts from autohausAZ. They have a different number listed for the 07-09 models. They have 20-114428

 

Vince knows his stuff he's correct the fronts are for the 5.0

The reason there are two part numbers is one is for the xk (black) the other is for the xkr (green) obviously were talking about the rears here (4.2)

 

I thought the old cars had one number and the new cars have a different number.
I also assume that the different part number are because jaguar part numbers are different than the aftermarket part number even though they are the same part.
i emailed belstein to see if they have feedback. It still doesnt make sense that the fault is only on one side.

 

Just experienced this very thing after a shock replacement. Check the connections on all the sensors that feed the system, if just one is loose, you 'll get that fault.

 

Point made. Do both rear struts measure 5.5ohms?

I am really tossing educated guesses here, but based on the service manual, and noting the part number you list, it isn't correct.
The number for the rears I came up with searching for 2010 with adaptive was C2P17674 while 2009 and earlier show C2P11466.

BOL

 

Apparently how far the suspension is compressed has a major impact on the ohm readings. With the car in the same location, the RR (which is the fault code) is 2.6 oh . LR is 12.6 ohm. LF 1 ohm. RF 6 ohm

 

I'm scratching my head here, because in my understanding, this should not be possible.

• Are you testing the shocks disconnected from the car?
• What is the quality of your Ohmmeter? (Note, ohm meters require an internal battery. Is it good?)
• Were you (-cough-) wearing your glasses?

Adaptive shocks will always measure between 2 - 3.5 Ohms or the Adaptive Damping Control Module will issue an adaptive fault.

 

I have a fresh battery in my fluke meter. Im definitely reading the meter correctly. (Stereo installer for 15 years) shocks are still connected to the computer when I measured. Do I need to disconnect the module to measure? When I apply weight to the suspension, the measurement fluctuates +/- 0.2 ohms

 

Ah, there we go (whew!)
Yes, you are to measure the shocks while disconnected.

 

With the module unplugged, front are both 2.8 oh . Rear are 5.2 ohm
